Polypropylene lined composite hose with stainless steel inner wire, and either galvanized steel (4091) or stainless steel (4094) outer wire.
Engineered with 100% chemical resistant barrier layers embedded in the hose wall to prevent permeation and leakage. Available in sizes from 1” to 4” diameter, hose assemblies are conductive and capable of full vacuum. A diverse selection of end fittings are available. Working pressures of up to 250 psi (17 bar) and temperatures of up to 100 degrees C (212 F).

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).
