Propress G
Range
General
Flow-optimised press connector system made of copper (99.9 % Cu-DHP), gunmetal or silicon bronze for copper pipes. Press connector for protecting the sealing element equipped with cylindrical pipe guide. Press connector from DN65 with stainless steel compression ring to ensure the mechanical strength of the connection. Suitable for concealed and pre-wall installations of manifold and riser pipes. The pressing force is located before and behind the sealing element seat.
