Product overview

REPL RIHTA Heavy Wall Heat Shrink Tubing (Coated)

REPL RIHTA Heavy Wall Heat Shrink Tubing (Coated) are hot melt adhesive lined heatshrinkable tubes used for environmental sealing of plastic and paper insulated cable joints rated up to 36kV.
RIHTA Part Numbers: 12/4, 16/5, 20/6, 30/8, 40/12, 55/16, 80/20, 100/30, 120/ 34, 140/37, 160/50, 180/60.

These tubes are made from thermally stabilised, cross linked, UV and weather resistant polymeric material and have a nominal shrink ratio of 3:1 and an unlimited. The tubes can be supplied in an uncoated form – with no adhesive layer (RIHTU) depending on the application.
