Key Features

  • Ground Joint Hose Couplings are all-purpose hose coupling.
  • These Couplings are designed for compressed air, steam, or fluid hose service where higher working pressure and increased hose coupling retention are required.
  • A hammer type female swivel nut with coarse thread allows for quick attachment to equipment with a metal to metal contact. A spud adapter converts the coupling to pipe thread. 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 NPT, female NPT or double male wing nut thread allow for versatility in configuring hose systems from tool to compressor, manifold, and piping systems
  • Hammer type female swivel nut is also available in gasket seal version. But not interchangeable with metal to metal sealing hammer union.
  • 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.
