The Tweetop Press Elbow 16x16mm is made from high-quality pressed brass (CW617), with a nickel-plated exterior for surfaces not in contact with water. It features a full anti-diffusion barrier and stainless steel clamping rings, along with EPDM O-ring gaskets for a secure seal. Designed for hot and cold water installations, central heating, and surface heating (underfloor/wall), it ensures reliable connections using U-type press tools. The two integrated O-rings guarantee a leak-proof fit, making it suitable for use in wall and floor grooves, as well as ice water applications.
