Introduction        
Soft polyolefin, flame-retardant, double-wall heat-shrinkable tube, seals and protects the connector back shell, branch line and the transition from connector to cable at high temperatures. High shrinkage rate, able to provide excellent protection for irregular shapes of various sizes.

 

Features        
Operating temperature: -55~125         
Minimum full shrinkage temperature: 110         
Shrink ratio: 3:1 & 4:1        
Environmental protectionRoHSELV compliant        
Color:Black
