Ground Joint Couplings are available in a larger size range than many other hose coupling styles.
The female swivel features a special coarse thread and over-sized hammer lugs that quickly seal the coupling tight against its special polymer seal (similar to a hammer union). Threaded spud adapters in male, female or double male wing nut thread allow for versatility in configuring hose systems from tool to compressor, manifold, and piping systems.
bolted interlocking clamps secure the ground joint hose coupling shank to heavy wire braid bull air hose, wire braid steam hose, or fluid transfer hose.
Using band type hose clamps will reduce the working pressure of the hose assembly and decrease shank retention.
