Steam hose fittings, couplings, and clamps are parts that connect steam hoses to compatible equipment in steam systems. They can withstand high temperatures and pressures and are commonly used in steam hose assemblies for steam cleaning, steam heating, washdowns, and other high-pressure steam applications. They are also suitable for use in fluid-petroleum and chemical applications. Steam hose barbed fittings have raised ridges that grip the insides of hoses to hold them firmly in place. Steam hose ground-joint couplings and coupling spuds are barbed, threaded fittings and bushings that connect two lengths of steam hose, or a single length of hose to equipment with compatible threads. Steam hose clamps secure steam hose fittings to hoses to form a tight seal.
