PTFE Tubing and PTFE Heat Shrink Tubing Are Different Materials

Some people might confuse PTFE tubing with PTFE heat shrink tubing. However, these are two distinct products. The only similarity between the two is that both materials are made using Teflon. Both are used in situations where you need good electrical insulation or have biocompatibility requirements. But heat shrink Teflon tubing is used when  there is a connection involved, as well as in areas that receive high stresses or high levels of vibrations, for example.

You Need to Know AWG Sizes to Select PTFE Tubing

You will need to be familiar with AWG sizes when selecting PFTE tubing. AWG is the abbreviation for American wire gauge, and is the standardization used for selecting the right type of wiring, based on gauge size. An AWG size can be determined using either millimeters or inches. For example, an AWG size of 10 is the equivalent of 0.1019 inches or 2.588 millimeters. The exact computations needed to convert millimeter or inches to AWG can be complicated. Luckily, there are conversion charts available to provide assistance to select the right AWG size.

Nylon Mesh Screen Openings Are Often Given in Microns

In order to determine the size of mesh opening you require for your nylon mesh screen, you will need to convert it to microns. Microns are a unit of measure, and are sometimes called micrometers. They are recognized by a symbol that looks like a small letter “u”. Many people use inches to determine the mesh opening. This can easily be converted to microns when you know how to perform some simple computations, or you can use a conversion tool instead.

How to Convert Nylon Mesh Screen Openings from Inches to Microns

To convert nylon mesh screen openings from inches to microns, you start by taking the equivalent of a one inch measurement, which is 25,400 microns. Then, divide the micron amount by the appropriate inch measurement. For example, if you need an opening that is ¼ inches, you would divide 25,400 microns by 4. If you need a 1/8th opening, you divide 25,400 microns by 8. On the other hand, if you need a 1 ½ inch opening, you multiple 25,400 microns by 1.5 inches. We also have a conversion calculator available on our nylon mesh page that will convert microns and inches both ways.

There Are Different Ways to Secure Stainless Steel Machine Screws

Stainless steel machine screws can be used in multiple ways, depending on where they are being installed. You can use them on their own to fasten together two or more individual pieces. In this situation, the screw hole may or may not already be pre-tapped. Another method is to pass them through an untapped hole, which is slightly larger than the screw. You then secure two or more pieces together, tightening the screw through a nut.

Inches Are Often Used as Lengths for Stainless Steel Machine Screws

The length of stainless steel machine screws is commonly given in inches. This is because most organizations within the United States use the English measurement of units, rather than the Metric system. It is possible to convert metric measurements into inches. You can either use a conversion tool or perform your own calculations, as long as you know whether to multiply or divide.

Straightened Wire Can Be Customized to Fit With Your Application

There are a variety of different applications and uses for straightened wire. This type of wire can be custom cut to specific lengths to fit in the area you require. It can be used by itself or can be passed through various types of tubing, such as hypodermic tubing or Teflon tubing. Other types of customizations some people require with this wire include bending, wire forming, and cleaning.

Working with Multiple Sizes and Types of Straightened Wire Requires a Storage Solution

It is ideal to have a storage method in place when working with multiple sizes and types of straightened wire. The easiest method is to store each type and size of wire in individual plastic storage tubes. You can label the outside of each tube to include detailed information about the wire, such as its length and diameter. You can also apply bar codes to the storage tubes when you use this type of system for inventory control and management.

You Can Order Standard or Custom Blunt Needle Kits

Several types of organizations use a wide variety of blunt needle sizes. One method for obtaining an assortment of needle sizes is to purchase them in a kit. Kits include a selection of different gauge sizes, ready to be attached to a syringe or other device. Standard kits include options for obtaining either ½ inch or 1-inch needles in assorted sizes. You can also custom order your kit, when other lengths are needed or you require specific gauge sizes.

 

What Processes Are Needed to Make a Blunt Needle?

 

A blunt needle is made using several different types of components. You will need a piece of hypodermic tubing in the proper gauge size, cut to length, with a blunt tip. Next, the tubing is attached to a polypropylene hub. This hub is often pre-threaded, so it can be easily attached to a syringe or bottle. Finally, any finishing touches are applied, like bending the tubing to create an angled needle.

Thin Wall Stainless Steel Tubing Is Finished Using Different Methods

There is a variety of methods used to finish thin wall stainless steel tubing. One method used is to cut the tubing into standard lengths, with no other finishing processes. Another method used is to cut the tubing to specific lengths and apply precise finishing processes. Finishing processes can include bending, beveling, cleaning and deburring the tubing.

 

The Inner Diameter Is Larger in Thin Wall Stainless Steel Tubing

 

Thin wall stainless steel tubing is ideal for situations where you want to pass a wire, cable or other smaller device through the center of the tubing. Since the inner diameter is slightly larger than regular wall tubing, you can achieve the proper clearance, without having to switch to a different gauge of tubing. When clearances seem a bit tight, even with a thin wall, another option is to consider extra thin wall tubing.

Super Elastic NiTinol Wire Is Used in Medical Settings

Super elastic NiTinol wire provides many useful benefits when used in medical industries. This type of wiring is able to transform and change shape at lower temperatures than shape memory NiTinol. For example, super elastic NiTinol can be used in place of stitches when closing up a wound. All that is required is that the wire be secured through a few sutures. The body will naturally heat up the wire, causing it to transform into its preformed shape, which tightens the wire and seals the wound.

 

Orthodontic Offices Can Use Super Elastic NiTinol Wire

 

Another medical setting that is ideal for super elastic NiTinol Wire is in orthodontic offices. This type of wiring can be included in the headgear and braces designed to move the teeth. The wire is first installed in its deformed state, and is heated using the ambient temperature of a person’s mouth. Once heated, the wire tightens as it attempts to return to its preformed shape. Using this type of wiring helps reduce the number of times braces and headgear have to be tightened as the teeth are moved.

FEP Shrink Tubing Provides Several Benefits over Other Types of Heat Shrink Tubing

FEP shrink tubing is just one of several different types that are available. It commonly comes in standard four feet sections, which you have to cut down to size. You can also obtain it in custom cut lengths when you lack the appropriate cutting tools. This particular type of shrink tubing is ideal for situations that require a lower shrink temperature than is needed with Teflon tubing. This tubing also provides optical clarity, greater flexibility, and high lubricity over PFA fluoroplastic tubing.

 

FEP Shrink Tubing Size Is Often Listed in Inches

 

The size of FEP shrink tubing is often given in inches and should not be confused with the tube’s length. This size is the diameter of the tubing, measure from one outside edge to the other outside edge. For situations where you are working with metric sizes, you will need to convert inches to millimeters or centimeters. You can find tools that perform the conversions automatically, or you can manually perform the conversion using the appropriate numbers. One inch is the equivalent of 0.393701 centimeter or 0.0393701 millimeters.

A Hypodermic Tube Is Able to Puncture Through Thin Layers

A hypodermic tube is commonly used to reach areas of the body just directly below the skin, but not normally much deeper. The tube is often part of a needle assembly, and used to draw blood or give injections. It can also be used to pass through other thin membranes and materials, when used in a laboratory or manufacturing setting. The small opening made by the tubing, often does not cause damage to the membrane or other material, while allowing liquids to be injected or removed.

Details You Should Know When Ordering a Hypodermic Tube

When ordering a hypodermic tube, you need to know several different details to get the correct type and size. First, you need to decide if you need 304 stainless steel, or 316 stainless steel. Next, you need to decide if you want the tubing cut to standard lengths or cut to custom lengths. You also need to know the gauge sizes you will require. Finally, you need to decide if you want the tubing included as part of needle assemblies or wire guide assemblies.
