Cryogenic Couplings – for LNG and Nitrogen Products

Cryogenic Couplings

EWFM Cryogenic Couplings have been designed specifically for use with nitrogen and LNG products which operate at temperatures of -163°C and -196°C. Ease of use, safety and reliability are of highest importance when handling temperatures as lows as these which what the cryogenics offer. It is made up of two parts, the hose unit and the tank unit.

Dry Cryo­genic Cou­plings are according to ISO TS 18683 and ISO 21593. This makes them suitable for the loading and un­load­ing of cryo­genic liq­ue­fied gases. Due to the temperatures being handled during a cryogenic process, this coupling is only available in stainless steel with PTFE seals.

For more designs, please head to our Coupling page where you can find a range of Manntek, engineered and API couplings.
