The ground joint hose coupling set is a three piece system featuring a hose shank, over-sized female swivel nut, and spud adapter. It is designed for compressed air, steam, or fluid service where higher working pressure, increased shank retention are required and a hammer type swivel nut is desired.
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 oversized 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.
