CABLE JOINTING AND SEALING

Our advantages

Beyond expectations 

we are aimed at bring reliable cable jointing and sealing SOLUTIONS.

We are inspired to do great work because we truly believe in what we do and we put our heart and soul into it.

Dual wall flexible tube

HSDT heat shrinkable dual wall flexible tubing, are made from cross-linked polyolefin and hot melt adhesive. The tubes are highly flexible and flame retardant, and designed for the application where need both insulation and moisture sealing.

 

Color: black, red, blue, yellow, etc.
