3-piece mixed PVC coupling gluing and threading male with gasket

3-Piece Mixed Coupling

The 3-piece fittings are ideal 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 an O-ring.

The connection sleeves are manufactured in smooth terminations, in this case with connections for gluing (female) and for threading (male). Complying with standards and with the possibility of adapting to other components. They incorporate an EPDM O-ring between the two couplings 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. In addition, we have three sizes available so that you can adapt your installation:

• 50 x 1 1/2"
• 50 x 2"
• 63 x 2"

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