* How to use it?
- 1. Wrap the cable wire with the tube, then use a heat gun heating it evenly until the wire was wrapped tightly.
- 2. Don't touch the tube until it becomes cool.
- Kindly Note:Make sure temperature of your heat gun is up to 212℉(100℃), then glue inside will soften and seal the connection.
Quick 4:1 Shrink Ratio: When heated, the heat shrink tubing shrinks to 1/4 of its original size, providing an even tighter seal. Shrink Temperature: 80-120°C (176°F-248°F), ensuring your wires are instantly connected.
Dual-Wall Adhesive Lined Heat Shrink Tubing: During heating, the outer heat shrink tubing tightly contracts, while the inner adhesive layer melts, sealing the connection area. This creates a tight and long-lasting seal, providing excellent protection.
Better Protection: The cable sleeves offers excellent electrical insulation, strong sealing, anti-friction, and high-temperature durability. It is also resistant to aging and has good toughness.
Widely use: Our 4:1 wire shrink wrap tubing is widely used in the power, electronics, telecommunications, marine and automotive industries. It is the good choice for insulation, sealing, and various cable-related applications.
The dimensions in the description refer to the size before shrinking, which is the diameter of the heat shrink tubing in its unshrunken, round state.
