Comments Off on PTFE Tubing and Hoses Manufactured for Aerospace and Aviation

Installation of PTFE tube has become an indispensable activity for every organization to conduct operating activities smoothly and protect the web of wires from any kind of accident. Often, known as polytetrafluoroethylene, in the beginning the PTFE was used only in specific industries. However it was back in 1950, because going through its versatility, soon became an integral part of almost every industry especially in aerospace where it is used in filling fuel in aircraft, tubing hoses , hydraulic hose, protecting doors and making easy assembling of aluminum and other metals followed by complete protection from any kind of damage.
Interestingly, the use of the Teflon PTFE tubing in aircraft is not stagnated only upto the above mentioned activities but, is also used in various applications for instance in edges of wings mounted on the aircraft. The low coefficient of friction feature found in it, which makes the aluminum rod installed in wings flap and slat smoothly while landing. Moving ahead, the Teflon PTFE starts acting as sheet of protection at the time when an aircraft lands. In absence of this fluoropolymer plastic, it is possible that aluminum rod might break during landing when it is starts coordinately with other wings.
Teflon Tubing for Areospace applications
The Teflon PTFE tubing system is not only used in aerospace industry but as mentioned above it is also used in various other industries in different form depending upon their requirement. In this regard it would be important to talk about PTFE spiral cut tubing for aircraft which plays an important role to cover the wires and cables and also used in other industries because of features like heat resistance, protection from abrasion and insulation. In spiral format, the PTFE tubes becomes expandable moving in upward and downward direction protecting the bunch of wires from abrasion which might take place due to heat.
The flexibility of Convoluted PTFE Tubing makes the smooth movement of wires bounded in bunch in any direction at an ease without any damage. The integration of features like chemical resistant, heat resistant and moisture resistant makes them a perfect option for various industries.

Comments Off on Improvisation at Its Finest: The All-Purpose Heat Shrink Tubing!

We all know how heat shrink tubing can do wonders for any system where cables or wires need to be protected. Whether you need something to insulate bare wires, cover wire splices, color code wires or bundle together some badly sprayed out network cables – heat shrink tubing can be used for anything and everything.

But what if you’re not an electrician or a network installer, then what?

Is the use of heat shrink tubing only restricted to wire and cable related applications, or can you do much more with it?

To find the answer to this question, we reached out our ingenious Tef-Cap team and our simply amazing Tef-Cap customers. The uses they suggested left us in complete awe.

So we decided to share some of these heat shrink uses with our readers too—the homeowners, the handymen, the hobbyists, and everyone in between.

It’s improvisation at its finest!

Heat Shrink as Pencil Grips


One of our customers, who just so happens to teach occupationally impaired children, told us that he uses heat shrink tubing as a pencil grip. Because the children he teaches have difficulty with motor skills, they write with pencils that are larger in size than your average pencils. Hence, these pencils can’t be fit with standard grips. By cutting down heat shrinks in shorter lengths, he can slip them around the pencils and heat-shrink them into place. This makes it easier for his students to hold the pencils.

Heat Shrink for Curling Iron Repair

This use was suggested to us by one of our staff members who is very particular and conscious about the hair style she wears. She told us that recently the plastic grip on her curling iron came off. She tried to put it back, but couldn’t. Of course, she could not use the curling iron with a bare handle as it was quite risky, so she came with a genius idea. She used the heat shrink tubing to cover her curling iron’s handle, and the fix worked.

Heat Shrink for Glass Repair

Have you ever found yourself in a situation, where one arm of eyeglasses snapped and you just didn’t know what to do to repair the pair? Well, we could not help you at that time (sorry for that), but now we can. We’ve got a fix for you. If you ever find yourself in a similar situation again, simply get a heat shrink from your local store, slip it over the broken ends of your eyewear and eyewear arm, and shrink it to size. It may not serve as a permanent fix, but it buys you enough time. And yes, it would also save you from short-term blindness.

Heat Shrink as Furniture End Caps

That outdoor furniture in your patio, it has constantly being leaving rust rings on your patio floor for the last year or so. And you’re absolutely tired of cleaning these left behind marks again and again. Well, you can save yourself from the inconvenience by installing heat shrink tubing onto the feet of your furniture. Those rust rings aren’t coming back—trust us!

Do you have any unconventional use of heat shrink in your mind that you would like to share with us?

Fits Like a Glove: Buying the Right Size Heat Shrink Tubing

Comments Off on Fits Like a Glove: Buying the Right Size Heat Shrink Tubing

Imagine if buying a heat shrink tubing was as simple as buying a coat. You measure the object you want to cover and then buy a heat shrink to fit.

Unfortunately, it’s not.

Buying a right size heat shrink is much more complex than buying a right size coat. Because the tubing shrinks, when heated, does not retain the same dimensions it originally has pre-heating.

As such, it’s common for buyers (especially, first time buyers) to make sizing mistakes when buying a heat shrink tubing, ending up with a purchase that just won’t fit into their application.

This piece will guide you on how to avoid sizing mistakes and buy a right sized heat shrink tubing for your application.

First things first…

Before we get into the nitty gritty of how to measure a heat shrink when purchasing one, it’s worth noting that heat shrink tubing is first made to the diameter it will be when it’s shrunk. After that, it is expanded and packaged for sale.

So when you buy a heat shrink tubing, its shrunk dimensions are already known; they’re stated on the specification sheet.

Having this explained, we can now move on to the actual measuring step.

Dimensions and Dimension Facts—You Should Know About!

When measuring a heat shrink tubing, there’re basically two types of dimensions you’ll be working with: i) Recovered dimensions and, ii) Expanded dimensions.

Recovered dimensions are the shrunken dimensions and expanded dimensions are the dimensions of the tubing in the stretched form.

On a typical heat shrink datasheet, you’ll find the following dimensions listed:

  • Recovered internal diameter
  • Recovered wall thickness
  • Expanded internal diameter

Let’s say you want to buy a heat shrink to cover a cable which has an outer diameter of 7 mm.

The heat shrink that you buy must have:

  • An expanded internal diameter greater than 7 mm
  • A recovered internal diameter of just under 7 mm

Please note that you won’t find the exact dimensions listed on a heat shrink tubing’s datasheet. They will always have some tolerance range which will be mentioned on the sheet. So make sure you keep that in mind.

What about the wall thickness?

It depends on the application in which you want to use the heat shrink. If wall thickness is really important for your application (for e.g. If you’re looking to insulate a piece of wire), we would recommend that you purchase a heat shrink tubing with the maximum recovered wall thickness.

Let’s take a look at another example.

Let’s say you want to buy a heat shrink tubing to insulate a cable wiring. The cable has a diameter of 7 mm. It has bare wires running through it which are 4 mm in diameter. Plus, the cable has a connector at each of its end, which has a diameter of 15 mm.

The heat shrink that you buy must have:

  • An expanded internal diameter greater than 15 mm
  • A recovered internal diameter of just under 4 mm

For wall thickness the rule is same as discussed above.

One more thing you should keep in mind…

A heat shrink tubing not only shrinks in diameter when heated, but it also shrinks in length. Although the change in length is minimal, usually 10% of the original expanded length. So if you need a heat shrink tubing to cover an object of length 2 meters, you should buy a heat shrink which is at least 2.2 meters long. You can later cut off the tailing end if you wish to.

And that is how you can buy the right size shrink tubing for your application that will fit like a glove.

Comments Off on Teflon Industrial Coating—Everything You Need To Know

Industrial coating refers to the application of protective material over wiring and other important equipment in order to ensure that it stays safe from harmful materials.

Teflon is one of the most commonly used materials when it comes to industrial coating. There are several benefits of using Teflon for industrial coating. Some of these benefits include:

Non stick surface

Teflon is extremely popular because of its non-stick feature. Sticky surface can be quite inconvenient especially if you are involved in the business of manufacturing cooking products.

It can completely ruin the product because of which these people prefer to buy products that have Teflon industrial coating. The liquid does not accumulate on the surface of the machine and instead just slides off.

You might want to know that the coefficient of friction on Teflon products also happens to be really low, because of which it is very easy for you to move machines.

Highly resistant

Another great feature of Teflon is the fact that it has high resistance to heat as well as water. This ensures that the material stays clean. It also prevents water from becoming saturated. You can simply wipe down the surface with a cloth. It does not take a lot of time and does not leave behind any kind of debris.

Teflon also has high resistance to heat. It can withstand the temperature of up to 260° Celsius. Due to its high resistance, Teflon is the ideal material in tasks, which involve use of excessive heat.

The process of industrial coating involves multiple steps, which include:

  • Primer
  • Full Coating
  • Sealant

You need to know that Teflon is an ideal sealing material. It is a strong electrical insulator and does not dissipate very easily. The level of frequency varies in different industrial applications because of which you need a highly resistant industrial coating material like Teflon.

It is not prone to chemicals

Chemicals can adversely affect the product. In some cases, they can also be quite dangerous. Teflon coating can be beneficial in this regard since chemicals do not easily affect it. It acts like a filter and prevents harmful elements in the chemical from causing any kind of damage.

You need to know that Teflon refers to multiple materials, which are all made of fluoropolymers. These include:

  • PFA
  • PTFE
  • FEP

All of these materials have different characteristics and you need to identify which one best fits your needs. Get in touch with us. We offer a wide collection of Teflon products, which include:
