contact with PTFE hose assemblies. PTFE hose assemblies may be braided with CRES
wire, polyester or para-aramid fibers. Hose assemblies may be equipped with aluminum,
CRES, titanium or nickel alloy fittings; and with fire resistant cover materials. All of these
constituent materials of PTFE hose assemblies must be compatible with all of the fluids
found in any particular application.
