## Description

Are you looking to fix a damaged wire, seal out moisture, or provide enhanced strain relief ? Wirefy adhesive heat shrink tubing is an easy to use solution for insulating and protecting wires, cables, connections and components. It can be used in a variety of of applications: marine and automotive wiring, outdoor and home repairs, RC hobbies, or giving your phone charging cable a second life.This is a moderately stiff dual wall heat shrink tubing with the internal adhesive layer. It is 3:1 shrink ratio tubing, which allows it to be used in significantly more applications compared to 2:1 shrink ratio tubing. When heat is applied, shrink tubing recovers and the internal adhesive layer melts. A small fillet of clear adhesive (about 1 mm wide) becomes visible at the end of the heated tubing. When cooled down it forms a rigid seal. Heat activated glue strongly adheres to wires or any other surface. This heat shrink tubing assortment comes organized in individual compartments to keep things neat and tidy.This electrical shrink tubing is UL listed and compliant with all relevant electrical standards: SGS, RoHS, Reach, and ISO9001. This wire heat shrink tubing is flame retardant.275 PCS Heat Shrink Tubing Kit Includes:-- 3/32" Heat Shrink Tubing - 70 PCS (15 Black, 15 Red, 15 White, 15 Clear, 10 Blue)-- 1/8" Heat Shrink Tubing - 50 PCS (14 Black, 14 Red, 8 White, 8 Clear, 6 Blue)-- 3/16" Heat Shrink Tubing - 75 PCS (25 Black, 25 Red, 10 White, 10 Clear, 5 Blue)-- 1/4" Heat Shrink Tubing - 45 PCS (15 Black, 15 Red, 6 White, 6 Clear, 3 Blue)-- 3/8" Heat Shrink Tubing - 25 PCS (8 Black, 8 Red, 4 White, 3 Clear, 2 Blue)-- 1/2" Heat Shrink Tubing - 5 PCS (5 Black)-- 3/4" Heat Shrink Tubing - 5 PCS (5 Black)

Review: a must to have on hand in the shop. Used for car wiring and to seal the ends with spade connectors to make a neat joint and protect the joint and reduce the chance of ingress. Also looks neater in engine bay - or wherever your using. Lots of different colours and size choice and inexpensive. Seal onto wire with a low flame on the blow lamp. But heat gun equally as good.
