The fluid-transfer coupling can be connected under full system pressure by rotating the female threaded heavy-duty ductile cast-iron wing nut or brass hex nut onto the mating male threaded tip.

The unit features a steel interchange and internal parts are brass and stainless steel with the body and top outer shells electroless-nickel-plated steel. A brass-body tip and poppet are combined with a steel valve for corrosion resistance. The coupling features minimum air inclusion during connection and minimum fluid spillage during disconnection.
