1.5:1 Shrink Ratio Adhesive Lined -45°C to 105°C

GPFS Adhesive-lined Heat-Shrinkable Tubing for Automotive Oil-pipe Protection

GPFS adhesive-lined Heat-Shrinkable Tubing is specifically designed for Automotive Oil-pipe Protection, providing preventive protection to brake line, fuel line, hydraulic line and other metal pipelines which are subject to bending or clamping during manufacturing, installation or operation.

Shrink Ratio: 1.5:1

Semi-rigid outer layer – mechanical damage prevention

Adhesive inner layer – seals against moisture & prevents corrosion

Easy installation – adhesive will not separate from pipeline

Operating temperature: -45°C to 105°C

Shrink temperature: 120°C
