Cryogenic Breakaway Couplings
Cryogenic Breakaway Couplings disconnect under excessive force, preventing spills and protecting equipment during the transfer of LNG, nitrogen, oxygen, argon, and other cryogenic liquids.
Material
Stainless Steel
Pressure
Between 0 to 25 bar

Ptfe
Engineered for extreme cryogenic conditions down to -196°C, these couplings act as the “weakest link” in hose lines or loading arms. Available in Breaking Pin (1”–8”) and Cable Release (2”–8”) versions, they automatically stop flow during drive-away incidents. Designed for high flow rates and minimal pressure drop, they ensure safe, reliable, and efficient cryogenic liquid transfer.
Description
Cryogenic Breakaway Couplings are engineered to prevent spillage and protect equipment during drive or pull-away incidents in tanker loading and unloading operations. Acting as the “weakest link” in a hose line or loading arm, these couplings automatically disconnect under excessive force, stopping the flow of cryogenic liquids and minimising product loss, downtime, and safety risks.
Designed for extreme cryogenic conditions, these couplings are suitable for liquefied gases such as LNG, nitrogen, oxygen, argon, and ethylene, with operational temperatures down to -196°C. They are widely used in the chemical, petroleum, and LNG industries around the world for safe and reliable cryogenic liquid transfer.
Cryogenic Breakaway Couplings are available in two variations: Breaking Pin (sizes 1”–8”) and Cable Release (sizes 2”–8”). The Breaking Pin version separates under a predetermined shear force, while the Cable Release type uses a tensioned cable to trigger disconnection, offering flexibility for different operational requirements.
These couplings provide high flow rates with minimal pressure drop, are durable under harsh conditions, and are designed to protect personnel, equipment, and the environment during cryogenic liquid handling.
