Parker's Hydraulic Quick Coupling Series H is a further development of the standard hydraulic coupling, with some new materials to stand up to heavy conditions. The body of the coupling is made of steel so that the coupling functions reliably even when subject to substantial lateral forces and high impulses. Series H is also available with pressure eliminator, i.e. connection is possible under static/residual pressure up to working pressure. An additional safety locking ring prevents unintentional disconnection.

The right plug for series H can be found under series T.
