Liaison m/f 3 pieces PVC for gluing

PVC Pressure Union

The 3-piece couplings are the ideal fittings for joining PVC pipes as they do not contain any metal parts and the outer diameter is smaller. These fittings allow the creation of detachable joints between different pipe sections.

The 3-piece couplings consist of two coupling sleeves, a nut and a gasket.

The connection sleeves are manufactured with smooth ends, in this case with a socket connection (female) and a socket connection (male). Complying with the standards and with the possibility of adapting to other components. They incorporate an EPDM gasket between the two sleeves to ensure watertightness, so there is no need to use PTFE tape.

With these couplings, multiple combinations of different types of plastics can be made. We have two sizes of 50 mm diameter and 63 mm diameter to choose the one that best suits your installation.

Thanks to the PVC-U materials that compose it, it can be used in water, chemical and waste pipelines, among other sectors.
