Heat Shrink Tubing



Polyolefin 2:1 Tubing

Polyolefin 2:1 Tubing


Polyolefin 2:1 heat shrink tubing is the most basic type of shrinkable tubing on the market. It shrinks 50%, from 1" to 1/2", and it's rated for 125°C and 600 volts. It comes in at least 7 colors and can be sent to you as a spool or 4' lengths. If you want us to cut your tubing to length please visit out value added services section to get a price online.

Polyolefin 3:1 Tubing

Polyolefin 3:1 Tubing


Polyolefin 3:1 heat shrink tubing shrinks down farther than 2:1 tubing. It shrinks 67%, from 1" to 1/3", and it's rated for 135°C and 600 volts. It's UL and RoHS approved and has high resistance to abrasion, chemichals and oils. This tubing, along with the first two types, are also flame retardant.

Polyolefin 4:1 Tubing

Polyolefin 4:1 Tubing


Polyolefin 4:1 heat shrink tubing shrinks down farther than 2:1 and 3:1 tubing. It shrinks 75%, from 1" to 1/4", and it's rated for 135°C and 600 volts. The picture to the left shows why 4:1 heat shrink tubing is used. Many wire harnesses and cable assemblies need shrinkable tubing to shrink down to different levels which makes 3:1 and 4:1 tubing perfect for those applications.

Polyolefin 2:1 Adhesive Tubing

Polyolefin 2:1 Adhesive Tubing


Polyolefin 2:1 adhesive heat shrink tubing is the same type of shrinkable tubing as above with a line of glue around the inside of the tubing wall. It shrinks 50%, from 1" to 1/2", and the glue melts when heated and makes a much more secure connection once it dries. It only comes in black and it can only be sent to you as 4' lengths.

Polyolefin 3:1 Adhesive Tubing

Polyolefin 3:1 Adhesive Tubing


Polyolefin 3:1 adhesive heat shrink tubing shrinks 67%, from 1" to 1/3", and has glue on the inside wall. The glued connection is nearly impossible to remove once it dries, so be sure to check your application before heating the tubing and activating the adhesive. It only comes in black and it can only be sent to you as 4' lengths. If you want us to cut your tubing to length please visit out value added services section to get a price online.

Alpha Heat Shrink Tubing

Alpha Heat Shrink Tubing


Alpha FIT® heat shrink tubing is a brand name of tubing owned and manufactured by Alpha Wire. They design heat shrink tubing products that meet the exceeded needs of their Xtra-Guard® electronic cables. Tubing temperatures and voltages match electronic cable temperatures and voltages, but Alpha Wire typically exceeds those standards and manufactures their own tubing products for that reason.

Everything You Need to Know About Heat Shrink Tubing



Are you aware that there are instances where a fire is often caused by a house's faulty wiring system? These are instances where the electrical wires often get exposed to extreme heat or become prone to abrasions or short circuits. These accidents would have been prevented if heat shrink tubing was used to protect the electrical wires from exposure.

Heat shrink tubing is a mechanically expanded tube or tape that you can use to protect your electrical wires or some minor electrical parts from harsh environmental elements. You can also use it to bundle up the wires so that they won't get tangled. It is also a way for you to improve the insulation of the wires.

A heat shrink tubing is usually made of polyolefin or nylon, materials that shrink whenever they are heated. After they cool off, they return to their original relaxed state or diameter. There are different types of shrink tubing. They were all designed depending on the way you intend to use them.

Flouropolymer tube or PFTE is a type of shrinkable tubing that has a consirable amount of resistance to punctures and harmful chemicals. It also has a very low friction coefficient and has a wide range of operating temperature.

Viton is another type of shrink tubing which is notable for its the huge amount of chemical resistance it contains. Often used as a hydraulic equipment, it is very flexible and can operate at a very high temperature. These properties make the Viton one of the most effective shrink tubing whenever extreme temperature is a factor to consider.

Elastomeric shrink tubes can maintain very high flexibility even if they are subjected to very low temperatures. The tubes are highly resistant to chemicals such as petrol and diesel and can withstand the most severe environmental elements. It is also highly resistant to abrasion.

Adhesive Polyolefin shrinkable tubing is often used in the military, railway and aerospace industries. These type of tubes tend to shrink really fast and are highly flexible. They are also widely manufactured and are considered as the most commonly used type of shrink tubing. However, they are noted for their low resistance to UV light. Their resistance to ultraviolet rays is so low that only the black Polyolefin tubes were recommended for outdoor use.

Silicone rubber tubings offer excellent resistance to abrasion even if they are scraped. They are also flexible. Fluorinated ethylene propylene or FEP is another type of shirnk tubing which is considered as the cheaper alternative to PTFE. Polyvinylidene fluoride are usually recommended for high temperature usage.

Shrink tubings are usually available in a wide range of colors. This color coding system make it easier for people to color code their connections. Some shrink tubings come with thermoplastic adhesive that help provide better adhesion and sealing.
