Boss® couplings are all-purpose hose couplings, universally recommended for steam hose connections. The spud part of the coupling serves as one half of a Boss® Ground Joint connection and is usually fixed to the equipment, the stem part that is clamped to the hose. The two halves are connected/disconnected by rotating the wing nut on the spud. When connected they achieve both a mechanical, and a pressure seal. A leakproof seal forms when the metal head of the stem makes contact with the polymer seat of the spud.
