Uses a special industrial plastic as the inner sealing layer, or a stainless-steel inner tube in the event of a rapid pressure decrease.
Composite rubber as the inner sealing tube, mainly composed of hydrogenated butadiene-acrylonitrile rubber with an excellent oil, seawater, thermal resistance, gas permeation prevention and more.
High strength fabric cloth as the inner cushion layer and protective layer
High strength steel wire as the skeleton layer
Glass fiber cloth as fire prevention layer
Composite rubber cover layer, made by chloroprene rubber, fire prevention, oil, abrasion, ozone, and aging resistant

Optional electric heating tracing feature
