Kingflex rubber foam insulation tube is made from the nitrile-butadiene rubber

Kingflex rubber foam insulation tube is made from the nitrile-butadiene rubber (NBR) and polyvinyl chloride(PVC) as main raw material and other high quality auxiliary materials through foaming, which is closed cell elastermic material，fire resistance, UV-anti and environmental friendly. It can be widely used for air condition, construction, chemical industry, medicine, light industry and so on.

Normal wall thicknesses of 1/4”, 3/8″, 1/2″, 3/4″,1″, 1-1/4”, 1-1/2″ and 2” (6, 9, 13, 19, 25 , 32, 40 and 50mm).

Standard Length with 6ft (1.83m) or 6.2ft(2m).
