RS PRO Blue, Red, White, Yellow No 3:1, Heat Shrink Tubing Kit 3mm Sleeve Dia. x Assorted Length

RS PRO Adhesive Lined, Flame Retardant Heat Shrink Kit

From RS Pro a portable heat shrink kit consisting of 75 pieces of high-quality adhesive lined or dual wall heat shrink tubing made from adhesive lined flexible, flame retardant polyolefin. The tubing contained in this versatile kit is in a range of colours and diameters to suit many different applications. The box itself is made from plastic with compartments inside for the different heat shrink tubing sizes and has a carrying handle on the top. This heat shrink kit is ideal for maintenance or repair technicians who require small quantities of various types of tubing.

What is Heat Shrink Tubing?

Heat shrink tubing is a type of extruded plastic tubing that can be cut to size and fitted over a wire or cable joint to protect and insulate the connection. When heated is applied the tubing shrinks permanently providing a protective seal. The amount it shrinks depends on its shrink ratio. When you buy the tubing it is in its expanded state, this expanded tubing has memory so when it is heated it returns to its original state

Features and Benefits of Adhesive Lined Flexible Polyolefin Heat Shrink Tubing

Flexible Polyolefin is a material derived from polyethylene and is one of the most commonly used insulating materials being both highly flexible, fast shrinking and durable. When heated it shrinks radially a third of its original diameter hence the ratio of 3:1. This heat shrink tubing has an inner adhesive lining, which, when heated, melts to form a watertight sealing around the joint. This type of heat shrink is also called dual wall heat shrink.

• Very flexible
• Adhesive lined for waterproof sealing
• Good adhesion to metals, polyolefin and PVC
• Flame retardant
• 3:1 shrink ratio, ideal for irregular shapes
• Operating temperature range of -55 to +125°C
• 110°C minimum shrink temperature
• Excellent electrical insulation properties
• Resistant to common fluids and solvents
• Excellent abrasion resistance

What is Heat Shrink Tubing Used For?

Heat shrink is very versatile and is used in both commercial and industrial applications for protecting, sealing and encapsulating cable joints and in-line components such as disconnect terminals and wire splices. It can also be used to carry out repairs on existing worn or torn cable or wiring insulation Applications include the following:

• Electrical insulation
• Environmental protection against moisture, dust, and chemicals.
• Mechanical protection to wires and small parts from abrasion
• Mechanical strain relief on cable and connector joints to prevent damage caused by flexing or bending
• Bundling and organizing harness wires, cable, and tubing
• Colour coded identification of cables, wires, and components

How to Use Heat Shrink Tubing

The diameter of the wire or cable is measured and the correct sized heat shrink tubing selected. A piece of the tube is cut to size which is long enough to cover the connection or joint after heating. This then slides onto the wire. After the cable or wire has been joined the piece of heat shrink shrinkable tube is moved over the joint and heated with a heat gun until it shrinks and forms a tight wrapping around the joint
