Quick couplings
HSP DC Cupla
The Nitto Kohki HSP DC Cupla is a steel quick coupling with NBR seal for pressure-assisted mating (DC: Double-Check). The programme covers 12 items in plug (HP-DC) and socket (HS-DC) configurations in nominal sizes 2, 3, 4, 6, 66, and 8. The DC mechanism allows connection and disconnection under residual pressure without first depressurising the circuit.
