Compression fittings with a cut ring, "monoblock" type, are dedicated to making dismountable connections made of cross-linked polyethylene pipes and multilayer pipes. They are used in heating, water and other installations (it is important that no aggressive working medium flows in them). In order to guarantee the perfect tightness of the connector, two o-rings were used. Fittings meet the requirements of EN 1254-3. NOTE - this fitting must not be poured into concrete or bricked up in building partitions!
