Polypropylene lined composite hose assemblies with a polypropylene coated steel inner and a stainless steel (T304 or T316) outer wire with chemically engineered 100% resistant barrier layers embedded in the hose wall to prevent chemical attack and leakage.
Hose assemblies are capable of pressurization and full vacuum with a diverse selection of end fittings and materials where chemical attack or erosion of the outer wire might require the option of a stainless steel outer wire. Working pressures of up to 250 psi (17 bar) with conformance to EN 13765:2010 and working temperatures of up to 100 degrees C (212 F).
Chemiflex® Heavy Duty Polypropylene Chemical Hose Type PSP951

Specially designed end fittings have been developed for use with Titeflex US Hose 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).
