SK/Metric couplings for concrete pumping - RM® Reliable Manufacturer

Couplings particularly suitable for working pressures from 85 bar up to 130 bar. Mainly used for concrete pumping booms as they allow the rotation of pipes. SK/Metric couplings are also suitable for both horizontal and vertical concrete distribution pipelines.
