Ground joint couplings ("Boss" couplings) use a metal-on-metal ground-seat seal — no gasket, no O-ring — for high-pressure steam and air service up to 600 psi. Three-piece assembly: hose stem (male shank), wing nut, and male / female spud. Industrial standard since the 1920s for steam-line service in refineries, food plants, and process industries.
