KBH high-performance solution with low temperature properties

The KBH breakaway couplings was particularly developed for low temperature applications / cryogenics and provides high flow rate with a maximum level of safety.

Using this breakaway coupling offers protection across the entire temperature range from -196 °C to +65°C.

Thanks to the breaking pins technology, the KBH separate the line at a defined tensile load.The two coupling halves are equipped with a non-return valve each that allows to close the line impermeably when it is separated and to exclude that the fluid escapes into the environment.
