Chem PTFE GS / SS Composite hose
Used for chemicals and acids

Bencheng Chem PTFE GS / SS Composite hose

Note: PTFE GS= Galvanized steel SS= Stainless steel 316/304

Manufacture
Bencheng Chem PTFE GS and Bencheng Chem PTFE SS hoses are constructed from multi-layers of thermoplastic films which form a sealing and permeation barrier, supported by fabric layers for mechanical strength. The hose layers are held and tensioned by internal and external steel wire helices. All hoses meet international standards including EN13765, BS 3492(1987)AX + BX and BS5842(1980) and can be supplied with external swaged and factory-fitted end connections to the customers’ requirements.

Applications
Bencheng Chem PTFE GS & Bencheng chem PTFE SS hoses are chemically compatible and mechanically engineered for those chemicals and acids which do not affect the PTFE lining and the polypropylene coated steel / stainless steel inner wire.
