The couplings used for the system are produced according to ISO 15875-5 standard requirements. The material used for the production is dezincification resistant brass enabling application of the couplings to the drinking water transfer.

Our screw-compression couplings are legibly marked, giving the nominal diameter, the carrier pipe wall thickness and pressure class (PN6 or PN10). The compact design of the couplings reduces the space required for their storage, while the innovative design enables simple assembling, without the need of the specialized hydraulic tools’ use. The couplings have taper thread as a standard feature complying with ISO 7 requirements.
