Black color Cable Accessories - Polyolefin Heat Shrink End Caps for the power network / grid
Model Number: SB-WRSFM
Heat shrink end caps are a simple yet effective method for sealing cable ends, pipe, conduit or other
similar objects.
Feature
● 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
