High-Temp Fluoropolymer Composite Hose

Fluoropolymer lined composite hose with stainless steel inner wire, and either galvanized steel (4131) or stainless steel (4134) 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 is available for aggressive chemical transfer applications. Working pressures of up to 250 psi (17 bar) and temperatures of up to 160 degrees C (320 F).
