GRP Full Face Couplings

Special design internal surface coated with EPDM provides tightness under high pressures. The internal surface of Superlit GRP coupling is coated completely with EPDM material and when compared with the smilar systems, it guarantees safer joining tightness and leak proofing. Superlit GRP Pipes produced by Centrifugal Casting and Continious Filament Winding systems, have the same external diameters. Due to this reason, the same GRP Couplings can be used in the pipes produced both methods.
