Blunt Needle Assemblies Are Useful for Industrial and Non-Medical Applications

A blunt needle assembly provides many useful applications when used in industrial and non-medical industries. The kinds of needles used by these types of businesses are normally non-sterile, because the processes where they are being used do not require sterile needles. The blunt tip is often desired over a sharp tip, because it helps to lower the risks of accidents, like poking through the skin. A blunt tip also helps prevent damaging other materials in the areas where they are being used. For instance, the needles may be part of your processes to fill ink cartridges. You want to make sure the needle can fill up the cartridge, but not be sharp enough to pass through the plastic chambers where the ink is contained within the cartridge.

Arts and Crafts Businesses Use Blunt Needle Assemblies for Creating Products

Small businesses which make their own arts and crafts products by hand often use blunt needle assemblies. Common applications include using the needles for applying glues, paints and adhesives. The needle assemblies are designed to be used with squeeze bottles, as well as syringes. The gauge of the needle, as well as the wall thickness, determines how effectively glues, paints and adhesives will flow through the tubing. Depending upon the types of products you produce, you might need to use multiple gauge sizes and wall thicknesses. You may also use custom and secondary processes in situations where you have specific requirements. Another option you can consider, to secure a variety of dispensing needles, is to obtain them in lab assortment kits.

Hypodermic Tube Is Offered in a Variety of Wall Thicknesses and Sizes

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.

Certain Sizes of Straightened Wire Can Be Inserted Through Hypodermic Tubing

Straightened wire is available in sizes designed to fit inside hypodermic tubing. The diameter of the wire determines which gauge of hypodermic tubing the wire will fit through correctly. For example, if the wire has a diameter of 0.022 inches, it can be inserted through 20 gauge hypodermic tubing. Passing the wire through hypodermic tubing helps protect it from getting bent. You may also use this method for applications and processes that require securing the wire at the ends where this added support is required to make the connection.

Guide Wire Assemblies Are Available Using Straightened Wire and Hypodermic Tubing

You can use straightened wire to build your own guide wire assemblies or have them custom built to fit your specific requirements. 36 inch lengths of wire are designed to be used with 30 inch lengths of hypodermic tubing to create the assemblies. These are the standard lengths available to order when you intend to build your own assemblies or cut them to your specifications on your own. In order to cut the wire and hypodermic tubing, you will need to have access to the correct cutting tools. Another option offered is to have each piece of wire and tubing custom cut and finished to your exact lengths required for your processes, should you lack the proper tools or do not want to spend time performing this extra step. Other secondary operations which you are able to take advantage of with this product include precision bending, cleaning and wire forming.

Cut FEP Shrink Tubing with an Overlap for Making Repairs

FEP shrink tubing is offered in standard four foot lengths. Prior to using the tubing, you need to cut it to the desired length for the area to which it is going to be applied. Before cutting the tubing, you should measure the location to determine the exact size required. For instance, you may be using the tubing to make a repair to the protective coating on an electric wire. If the area where the coating is cracked or missing is four inches, you would want to cut your FEP tubing to a length of six inches. By cutting the tubing slightly larger, it will create overlap at each end of the damaged location on the wire and help to ensure the wire is properly resealed. In situations where you use a specific length of tubing on a regular basis, you might want to consider ordering large quantities already custom cut to your desired sizes.

FEP Shrink Tubing Is Suited for Most Types of Applications and Environments

You can use FEP shrink tubing for a variety of applications and purposes in locations where extreme heat is not an issue. You are able to use this tubing just like other kinds of heat shrink tubing for wire splicing, electrical insulation, moisture and corrosion protection and bundling of wires and cables. FEP has a shrinkage temperature around 420 degrees Fahrenheit, plus or minus 20 degrees. This makes FEP tubing suited for environments where temperatures do not exceed 400 degrees Fahrenheit. In cases where temperatures exceed this amount, you will want to use PTFE heat shrink tubing, instead, because it has a much higher shrinkage temperature.

Thin Wall Stainless Steel Tubing Is Used When Working With Thick Fluids

Precision delivery of thick fluids and liquids can be accomplished by using thin wall stainless steel tubing. Because the inner diameter of the tubing is larger than regular wall, it allows fluids to flow better and at a faster rate. You might need to use this style of tubing for processes and applications where glues, adhesives, lubricants and greases are being applied to specific locations on parts and components. Delivery methods include using syringes, bottles and automated machinery. Depending on your exact processes, you may also need to have the tubing custom cut to size or bent at a specific angle in order to reach the area of application.

Non-Sterile Thin Wall Stainless Steel Tubing Is Used for Industrial and Medical Applications

Non-sterile thin wall stainless steel tubing is designed to be used for industrial applications and certain medical applications which do not require sterilization. It is common for the tubing to be attached to polypropylene luer hubs and made into dispensing needles with a blunt tip for certain processes. The needle assemblies are able to be attached to a syringe or bottle for easier delivery. For instance, in dental offices, this type of delivery system is often used with various liquid materials used to make molds, dentures, implants, veneers and tooth-colored fillings, as well as for procedures used to whiten teeth and supply fluoride treatments. Using the needle assemblies allows for precision delivery to create the desired product in the correct size and shape, and to  ensure the proper amount of fluid is used.

The Size of Mesh Openings Determines the Effectiveness of Nylon Mesh Screen

When using nylon mesh screen, the effectiveness of filtration is directly related to the size of the mesh openings. In order to achieve the desired filtration results, you should select screen that has openings smaller than the particles you want to remove. In situations where there are multiple particle sizes, you may choose to use several layers of screening in order to remove larger particles, first, and smaller ones as they pass through each layer.

Other Processes besides Fluids and Liquids Can Use Nylon Mesh Screen 

While nylon mesh screen is commonly used for applications involving fluids and liquids, it can also be used in for other processes. For example, this product is frequently used in insect research, in order to contain the insects during a study. The screen allows the insects to receive air, but keeps the insects in their desired locations and prevents them from escaping.

Different Wall Sizes Are Offered on 2:1 PTFE Shrink Tubing

PTFE shrink tubing with a 2 to 1 ratio is available is different wall sizes. You can choose from standard wall, thin wall and light wall, depending upon your needs and requirements. For example, with AGW size 20, the minimum expanded inner diameter is 0.060 inches and the recovered inner diameter is 0.039 inches for all three wall sizes. However, the thickness of the recovered wall will vary, with regular wall being 0.016 inches, thin wall being 0.010 inches, and light wall being 0.006 inches, plus or minus 0.003 inches.

Recovered Wall Sizes of PTFE Shrink Tubing Are Less If They Are Restricted 

The recovered wall size of PTFE shrink tubing can be less if the tubing is restricted in some manner during shrinkage. This is true regardless of whether you use standard wall, thin wall or light wall tubing. One cause for restrictions in the recovered wall size is when the tubing is placed around wire that has a larger diameter than the recovered wall diameter.

Several Industries Use PTFE Tubing for Various Purposes

Industries which use PTFE tubing include automobile manufacturers, chemical processing plants, medical equipment manufacturers and electrical supply manufacturers. The reason this kind of tubing is used by all of these industries is because of its useful properties. PTFE is able to withstand extreme temperature conditions, both hot and cold. PTFE also is resistant to corrosion from many types of liquids, including water and chemicals, and makes a great insulating material.

PTFE Tubing and PTFE Shrink Tubing Are Made from Teflon® but Perform Differently 

PTFE tubing is not the same as PTFE heat shrink tubing. While both materials are made from Teflon®, they perform differently. Heat shrink tubing reduces in size when the correct level of heat is applied. On the other hand, regular Teflon® tubing does not shrink. If a large amount of heat is applied, it will melt. The amount of heat required to melt Teflon® tubing is around 650 degrees Fahrenheit. Because of the high melting point, this makes using Teflon® tubing ideal for extreme conditions and environments.

Self-Tapping Screws Are Not Considered Stainless Steel Machine Screws

Some people easily confuse self-tapping screws with stainless steel machine screws. However, self-tapping screws are not considered machine screws because of the processes used to manufacture the screws. Both products are made from stainless steel and are miniature, but those are the only similarities. Self-tapping screws have small flat heads and are type BA. They include a gimlet, or sharp point for self-taping through various materials. They are used for fastening processes which use thin plastics, metals or wood.

Stainless Steel Machine Screws Are Available with Different Heads and Sizes 

Stainless steel machine screws are available for applications where the screws are applied through various materials with holes that are already pre-drilled and pre-tapped. There is a wide range and selection offered with different screw heads including slotted fillister, slotted pan head, Phillips flat head, Phillips pan head, and slotted pan head. The lengths and sizes available range from #0000-160 to #8-32. The head and drive styles do vary based upon the size.

Industries Use Hypodermic Tubing for Different Applications and Purposes

Hypodermic tubing is used for a variety of applications and purposes. Some industries use this product as part of guide wire assemblies. Other business operations use tubing to deliver fluids to specific locations during production processes. The tubing can also be custom cut to specific sizes and attached to polypropylene luer hubs to create needle assemblies. Other custom finishing processes like bending, beveling and deburring are offered in order to create the tubing to fit your needs and requirements

Hypodermic Tubing Is Available in Three Different Wall Sizes 

There are three different wall sizes available in hypodermic tubing, which include regular wall, thin wall and extra thin wall. As the wall sizes become thinner the inside diameters of the tubing increase. However, it should be noted that the gauge sizes do not change, nor does the outer diameter change. Using thinner walled tubing can help resolve issues, when working with thicker fluids, or anytime fluid flow rates need to be increased.
