## Overview

Wirefy’s 190-piece heat shrink tubing kit features a market-leading 4:1 shrink ratio with dual-wall construction and adhesive lining for waterproof, abrasion-resistant insulation. Pre-cut in five common sizes, it’s UL certified and perfect for marine, automotive, and home electrical projects requiring durable, professional-grade wire protection.

## 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 4:1 shrink ratio tubing, which allows it to be used in significantly more applications compared to 2:1 and 3:1 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.

Review: 4:1 Shrink tubing - I ordered this product after research and reviews. Was not disappointed it’s really great stuff I’m a newbie in doing van electrics and solar install and wanted the wiring to be safely protected some may think it’s overboard but I wanted good coverage and sealing. This 4:1 heat shrink was so easy to use I did procrastinate on what size trying to work that out initially but once I got going it was fine I used a heat gun and then welding gloves to protect my hands. Anyway the result was just what I was hoping for and has given my cables of various thickness a really good wrap. Swift delivery and would have no hesitation in re ordering from this seller, many thanks.
