Most researchers we work with don’t order a 60″ piece of hypodermic tubing from us because that’s exactly the size they need. They order it because it’s the industry standard, and they’ll figure out how to make it work for their application once it reaches the lab. But as the resource for R&D, that’s not good enough for us at Component Supply. We know there is a better way. That’s why our fabrication division exists. CS Custom Fab can cut, deburr and clean this material to our customers’ specifications with speed, affordability, and precision.
But we know our R&D friends are busy, and the extra steps of requesting a quote or sending a drawing are sometimes cumbersome – especially if you don’t know what you’re getting. So, we’ve decided to send you a sample of our straight and bevel cut hypo tube whenever you purchase any quantity of hypodermic tubing. We’ve always believed that it is our responsibility to put the best components in the hands of the brightest researchers and product designers so they can change the world. We just had to get these samples into your hands so you can see exactly what we do in CS Custom Fab that makes the work of our customers so much more efficient.
One more thing: we treat our stock cut pieces the same way: http://bit.ly/2BLHlix. These pieces are cut, deburred and cleaned just like our custom jobs but with no minimum. We look forward to hearing from you!
The mission of Component Supply is to be a resource for reseachers and product designers by connecting them with the components and knowledge they need to change the world.
At Component Supply, we pride ourselves on being a resource for research and development with our comprehensive offerings, short lead times and low minimums. But, sometimes that’s not enough. Most of our customers don’t need a 60” piece of hypodermic tubing, a 72” piece of wire or a linear yard of mesh. The material needs some secondary operation performed on it for their application.
That’s where CS Custom Fab comes in by specializing in the quick, efficient modification and fabrication of parts for both research and production. Our long history of working closely with researchers and developers enables us to understand how a modified component can streamline a design or process. We work with engineers who are designing products in the earliest stages of development, and we enjoy the challenges that come with adjusting their designs. We excel at developing efficiencies in production to keep up with increased demands. Our ability to draw from various products and the depth of material we have on hand allow us to meet the production needs of our customers. Component Supply’s Custom Fab engineers can help you work through an idea you are pursuing, provide insight into your drawings and produce quality products quickly.
At Component Supply, we understand the challenges facing research labs. Knowing the stress of budget constraints, fast-approaching deadlines and rising expectations in technological advancement, our Supply and Custom Fab divisions are assisting from the earliest prototyping stages through the transition into production. It’s just another way we fulfill our mission to connect researchers and product designers with the components and knowledge they need to change the world.
We have been supplying and working with hypodermic tubing since 1964. Whether it’s small quantities for researchers and developers, tubing for production or custom cutting or fabricating parts from hypodermic tubing, we have learned the needs of our various customers when it comes to standard lengths, tolerances and packaging.
In general, we know that most people do not need a 30-inch or 60-inch piece of hypodermic tubing. Most users will do something else with it either in-house, or they’ll have us make what they need. But regardless, customers buying standard lengths for production or R&D really do (and should) have some standards. For example, holding a +/-0.5-inch tolerance on a piece of tubing for 30 inches or 60 inches long should not be a challenge. In fact, holding a 1/8-inch tolerance shouldn’t even be a challenge. But, even though the need for grace is understandable in some mill operations, at the very least the tubing should come at least OD deburred on a buffer. This is a step that should be expected from customers. Many will argue that it is an unnecessary step that adds cost, but it is a service and benefit to the customer, even if they are going to process it anyway. It gives them a good, clean starting point to work from and allows tubing to be flush next to each other when such alignments are required for certain operations. Finally, the tubing should be packaged in a way that it is protected and can be well organized and identified. Some smaller sizes require shipping in a stiff poly tube, but we typically ship all our tubing this way for protection. Some of the larger sizes can be shipped in poly sleeves, but should be bundled in a way that the tubing is protected, and the bundle is rigid enough to prevent bending.
Naturally, we think our way of supplying it is the best way, especially after years of listening to what our customers appreciate. But, even though we believe this is the standard of what customers ought to expect from their supplier, there is always room to be better. So, if you have seen something done that made an impression or makes sense that we haven’t thought of when it comes to supplying hypodermic tubing, please don’t hesitate to let us know.

Let’s face it, bending a thin, little, hollow tube that’s smaller than a 1/16” diameter takes virtually no effort at all. The rub comes when you still want to be able to pass a gas or a liquid through that tube after it is bent.
Here’s the problem: Even though stainless steel hypodermic tubing is a full hard tube when you get down into the very small ODs like 0.013”- .032,” the tubes do not have enough tensile strength to remain at the radius they are formed. They spring back and you wind up having to bend them at a much smaller radius than your finished radius, thereby compounding your problems.
So, to start mitigating this problem, you need to address these three questions. How big? How steep? How long?
How big (or small) is the OD and ID of the tube I need to bend? Generally speaking, the larger the diameter, the easier the tube is to bend. However, the thinner the wall, the more likely the tube wall is to collapse while being bent.
How steep of an angle do I need to bend? Obviously the greater the angle of bend, the more difficulty you will have in maintaining the wall integrity. We recently did a job for a customer who needed a 135° bend (in essence a V shape.) In this job, the issue was not how to maintain the tube’s ID, but how to minimize and control the collapse of the tube walls during the bending process.
How long can the radius be? The compression/tension forces on the tube walls are exponentially reduced as the radius increases. So your success rate will significantly increase as the radius increases.
So, before you design your next project incorporating some little innocuous bent hypodermic tubing consider these three very inter-related issues, and if there’s anything we can do to assist your process, please contact us: firstname.lastname@example.org.

Looking at our product offering it is easy to see we are “heavy” in the area of tubing and fluid handling components. Within the world of tubing products we supply a lot of hypodermic tubing. I wanted to put together the reasons why this is the case because some of them may help buyers and users make good purchasing decisions, and at the same time I get to brag a little about what we have done here at Component Supply Company.
We have work very hard to offer the largest selection available of hypodermic tubing in stock with no minimum order quantity. On top of that, we can issue a material certificate for our tubing, even one 30 inch length, and ship it out the same day. This makes us unique from all other suppliers of hypodermic tubing. There are places you can purchase very small quantities; but not many and they are typically expensive, and I am not familiar with any that will, or can, provide a material certificate with chemical composition. Material certificates are not uncommon for certain suppliers, however. There are usually just large quantity requirements for purchase and shipping an order out the same day is not common for these companies. This is what makes us different from other suppliers on both the small quantity and production quantity side. If I had to sum it up, it would be that we provide material certs. for customers needing small quantities and we can ship production quantity orders the same day.
Our tag line is “The R&D Hardware Store”. We believe this is true, but it is a little deceiving. It is true in the sense that we do supply small quantities to researchers and product developers. However, it implies that is all we supply. In actuality, we supply large quantity hypodermic tubing orders at very competitive prices to hundreds of companies. We also custom fabricate parts by precision cutting, beveling and bending hypodermic tubing as well as produce custom needles. We handle this material so much on a daily basis that we have been able to listen to our customers to find out what is important and develop efficiencies so we can meet the expectations of both the R&D and production user of hypodermic tubes.
Whether you decide to use Component Supply as your hypodermic tubing supplier or not, keep these things in mind. If you need a small quantity and a material certificate, make sure the supplier is able to provide one and understands the difference between a material certificate and a certificate of conformance. If you are purchasing larger volumes find out what the turnaround time would be for the quantity you are looking for. All in all, most of the companies that supply hypodermic tubing are good companies. We are obviously proud of the services we can offer and the unique role Component Supply plays but, as you look around, you will find good quality and good service throughout this industry. That being said, we hope you still choose us.
Gauges are used as the measurement of the diameter for hypodermic tube. Unlike other measurements, where the size increases proportionate to the number, gauges actually decrease in diameter as the number increases. It is important to remember this when you are ordering your tubing, to ensure you receive the right size. For example, 10 gauge tubing has an outer diameter of approximately 0.133 to 0.135 inches, whereas 15 gauge tubing has an outer diameter ranging from 0.0715 to 0.0725 inches.
In addition to remembering the information about gauge sizes, you also need to determine the correct wall size to order. Hypodermic tube is available in three different wall options including regular, thin, and extra-thin. While the gauge size and outer diameters of each wall remains the same, the difference is the size of the inner diameter. As the wall becomes thinner, the inner diameter increases in size. Looking at 10 gauge tubing, you will notice the inner diameter of regular wall is 0.104 to 0.108 inches, thin wall is 0.112 to 0.116 inches, and extra-thin wall is 0.1165 to 0.120 inches.
The reason there are three different wall sizes is because some applications require a specific gauge of tubing. However, the rate at which fluids are able to pass through the tubing could be an issue. In order to make fluids and viscous materials flow easier, you are able to switch from regular wall, to thin wall or extra-thin wall tubing. The added increase in the inner diameters does help to increase flow rates.
Hypodermic tube is available in a variety of sizes ranging from 5 gauge to 36 gauge. This type of tubing also is supplied in three different wall sizes to fit with your specifications, including regular wall, thin wall and extra thin wall. Tubing comes standard in thirty and sixty inch lengths with secondary finishing services available to customize tubing to fit with your own specific requirements. In situations where you frequently use one, two or three inch lengths of this tubing, you are able to order it already cut to the desired length and keep a stock of it on hand. There is also one and two inch legs of tubing available already bent to a ninety degree angle. In cases where you use a variety of sizes and wall thickness, you are able to help keep them organized and undamaged by storing them in round plastic storage tubes.
Different Applications and Uses for Hypodermic Tube
Many different pharmaceutical and industrial processes use hypodermic tube for various applications and processes. For instance, one common use is to pass straightened wire through the interior of the tubing when it is being used as a guide wire assembly. Another purpose for the tubing is to have it cut to custom lengths and attach it to polypropylene luer hubs in order to create dispensing needles. Dispensing needles are used to deliver fluids, liquids, glues, and adhesives in desired quantities, depending upon the desired application or process. You are also able to use hypodermic tubing adapters along with standard compression fittings in order to connect this kind of tubing to plumbing circuits.
You can find a wide assortment of wall thicknesses and gauge sizes of hypodermic tube to fit your own specific requirements and needs. This type of tubing is offered in standard lengths of 30 inches and 60 inches. You are also able to have the tubing cut to custom lengths for processes where you require a large quantity of a specific size. Other options you might also obtain are custom bending, beveling and deburring. You are even able to have the tubing cut to length and attached to polypropylene luer hubs and made into needle assembles. It should be noted that bending processes are better suited for regular wall tubing than thin wall or extra thin wall tubing.
Hypodermic Tube Is Used for Special Functions in Certain Industries
There are certain industries which use hypodermic tube for special functions and purposes. Fishing supply manufacturers, henna artists, automobile manufacturing, aquarium supplies and tank manufacturers, printer ink jet cartridge manufacturers, food production operations and others rely on this type of tubing for fluid delivery. The tubing used in these businesses is designed to help with precision delivery of the various fluids and liquids in the correct locations. Combining the tubing with bottles, syringes or automated equipment allows for exact amounts to be used, and aids in reducing waste of these raw materials. For instance, henna artists need to ensure the correct level of ink is carefully applied in the right locations. Larger diameter openings can be used for situations where designs need to be fully filled in with ink, while still retaining control of how fast ink is released.
You have several different options for obtaining the hypodermic tube you require for your applications. For example, you might order a regular supply of short lengths of tubing such as one inch, two inch or three inch sections. Rather than having to order the tubing using custom cut finishing process for these sizes, you can find it offered in the quantities you require already precision cut, deburred and cleaned.
Hypodermic Tube Is Available in Small Sections with a 90 Degree Angle
You might have certain processes and applications which require your hypodermic tube to be bent at a 90 degree angle and be cut to a small length. In the past you may have had to use custom finishing services to have the tubing bent. However, you can now obtain it already prepared at this angle in both one inch and two inch leg sizes. In situations where you need larger leg sizes you are still able to order these to your specifications using secondary finishing services.
Sometimes it is necessary to customize hypodermic tube before it can be used. You might need to cut it down to specific sizes or you could require a unique angle to be applied. You are able to obtain these types of custom finishing processes whenever you order your tubing, as well as several others to fit your project’s needs and requirements.
You Can Order Hypodermic Tube in Lab Kits with the Sizes You Need
Depending upon the types of applications and purposes you use hypodermic tube you may require a variety of gauge sizes and lengths. You will find lab kits available featuring a wide assortment of the tubing you require, as well as the ability to order your own customized kits for your organization.
