Adapter fitting providing a smooth transition from plastic to metal. Features threaded galvanized steel body and plastic spigot.

This adapter  provides a smooth transition from plastic to metal. While the threaded end screws to a steel pipe or a metallic pipe fitting, the plastic spigot at the other end may be welded to a polyethylene pipe using different types of electrofusion fittings as per DIN 8075. This fitting uses a combination of elastomeric seals and significant interferences to ensure a leak-free design. The joint, designed to be stronger than the polyethylene pipe, exceeds pullout requirements.


Materials of construction: Body and expansion sleeve: galvanized carbon steel; Plastic adapter: HDPE; O-Rings: NBR
