applications the fluid may be replaced by a setting resin to resist long-term back pressure and relaxation of the copper membrane.

WRAS-approved Redman fitting, as barrier integrity is preserved in the joint area. Joints are rated for cold water at 16 bar, and the range of fittings includes elbows, couplers, flange adaptors, reducers, tees, flanged tees, repair joints and duck foot bends.

The fittings consist of an epoxy coated mild steel outer casing with an internal coaxial copper membrane, plus a polymeric coated (Rilsan) mild steel (stainless steel optional) insert. The joint is made by a purpose-designed hand pump used to inject a non-toxic biodegradable fluid through a nipple into the cavity between the mild steel outer and the copper inner. At 260 bar the copper insert is permanently deformed, forcing the PE pipe onto the insert, forming an end load resistant joint. Once the joint is made, the pressure may be released. For high pressure
