Cryogenic Couplings from MannTek are designed for safe, fast, and spill-free transfer of cryogenic liquids. With a simple push-and-turn action, these couplings automatically open the valve, creating a secure, tight-seal connection that minimises leakage, reduces downtime, and ensures maximum operator and environmental safety. Built for extreme low-temperature applications, they are ideal for LNG, liquid nitrogen, oxygen, and other cryogenic processes where reliability and performance are critical.

Description

Cryogenic Couplings are designed for the safe transfer of nitrogen and LNG products at extreme temperatures ranging from –163°C to –196°C. Prioritising safety, reliability, and ease of use, they are ideal for demanding industrial and energy applications where precise and secure connections are essential.

The system consists of a hose unit and a tank unit, allowing efficient and secure loading and unloading operations. Manufactured to meet ISO TS 18683 and ISO 21593 standards, the couplings are constructed entirely from stainless steel and fitted with PTFE seals to ensure maximum durability and leak prevention.

Perfect for handling ultra-low-temperature liquids, these couplings provide reliable performance for LNG, nitrogen, and other cryogenic applications.
