Fluoropolymer (PTFE or ECTFE) lined composite hose assemblies with a standard T316 stainless steel inner wire and a galvanized steel outer wire with chemically engineered 100% resistant barrier layers embedded in the hose wall to prevent aggressive chemical attack and leakage.
Hose assemblies are capable of pressurization and full vacuum with threaded or flanged end connections for the arduous marine service conditions and suitable for aggressive chemical transfer applications. Working pressures of up to 250 psi (17 bar) with conformance to EN 13765:2010 and temperatures of up to 100 C (212 F).
MarineMaster® Fluoropolymer Composite Hose Type 1171GGF, 4171SGF and 4174SSF
This type is recommended for heavy duty marine transfer service where a chemical resistance of PTFE lining is required. It is designed to handle liquid chemicals and acids not compatible with standard heavy duty polypropylene hoses and is suitable for dock, barge and ship transfer applications. A stainless steel outer wire is available for applications that need to withstand corrosive environments of petrochemical vapors and rigorous handling as used on a maritime vessel.

Specially designed end fittings have been developed for use with Willcox Composite hoses that have a unique leak-proof sealing face and specially machined helical spiral shank which engages into the corresponding internal helix wire when secured into the hose by either crimping or swaging the external ferrules.
Pressure based on safety factor 4:1. Dimensions and weight are approximate and are subject to change. For additional technical data such as pressure drop, max. flow rates and tensile strength, please consult Titeflex US Hose engineering. Increased operating temperatures will reduce working pressure of the assemblies. Fitting pressure rating may limit working pressure of the assembly. Rated working pressure is @ 70°F (21°C).
