Product Description

Polyolefin Heat Shrink End Caps
Model Number: SB-WRSFM

Heat shrink end caps are a simple yet effective method for sealing cable ends, pipe, conduit or other similar objects.

 

Features

• 2:1 shrink ratio   

• Superior resistance to weathering

• Resistant to common fluids

• Standard adhesive liner provides coated hot melt adhesive resists continuous operating temperature

• Shrink temperature: start at 110ºC, and fully recovered at 130ºC
