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).
