Our steam couplings consist of "Boss" ground joint seal couplings and "DIN" steam hose fittings to BS EN 14423 made of plated or stainless steel and brass alloys. They are supplied with corresponding "Boss" clamps with gripping fingers and safety clamps.
Steam couplings are sealed with metal-to-metal face or rubber sealing rings. Maximum working temperature +120°C (248°F) for hot water and +210°C (410°F) for steam.
Sand holes are deadly to pressure steam applications. Our made Boss couplings by investment casting for greater mechanical intensity and proved so through Xray penetration tests performed by renowned testing company SGS.
