About this item

  • 【4:1 super performance】: a shrink ratio of 4:1 means that it shrinks to 4 times its original diameter and allows a tight seal. It is currently the new product with the highest shrinkage rate on the market.
  • 【More inner adhesive】: our heat shrink tubes contain a special inner adhesive that overflows after shrinking the hose and connects firmly to the cable to ensure a tight connection and at the same time play the role of waterproof and dust-proof insulation to achieve effective protection.
  • 【Premium material】: our heat shrink tubes are made of high-quality, flame-retardant polyolefin material, which has the advantages of good electrical insulation, good tightness and corrosion resistance, which ensures a long service life and reliable performance.
  • 【Easy to use】: these heat shrink tubing are easy to use and can be shrunk in seconds. Simply cover the bare wire section with the heat shrink tubing and heat with a soldering iron or heat gun.
  • 【Technical data】: temperature min. - 55 °C, max. + 135 °C, shrink temperature 90 °C


Product Description

Heat Shrink Tubing
heat shrink connectors

Waterproof

4:1 Heat shrink tubing shrinks around wires and make a tight seal. As the glue flows, it squeezes the air out and fills any gaps between the wire and the tube, which makes the connection waterproof.

4:1 super performance

Heat activated adhesive inner layer

This is a waterproof shrink tube with an inner adhesive layer. When heated, the shrink tube shrinks and the inner adhesive layer melts. When it cools, it forms a hard seal. The heat-activated adhesive adheres firmly to the wire.

I'm using this for connections on outdoor solar lights and for the last few months it has really worked well. It REALLY shrinks up and fits tightly.

This heat shrink does the job well. It’s much stiffer than expected. The cable doesn’t bend or flex very well at all now.If you want to maintain flexibility in the cable, get shrink without glue.

I used this for handles on my pliers and it worked excellent. I would recommend it. When heated it would shrink and grip the pliers like I wanted.

This is very heavy duty shrink tubing that shrinks down to 4x it's original size. It's got glue on the inner wall which can seal joints from water and debris. Once shrunk it is very durable and can withstand abrasion. I love this stuff. Highly recommend it!
