Emergency release couplings (breakaway couplings)

Emergency release couplings – general information

Emergency release couplings (breakaway couplings) protect against the consequences of accidental, excessive pulling force applied to a flexible loading/unloading hose assembly connected to the piping on the system, when a tanker truck, which is being unloaded, drives away and the hose is still attached. This can cause the hose to burst and the conveyed substance to spill. In this situation, the emergency release coupling installed on the loading/unloading hose assembly disconnects, and the valves in both halves of the coupling close, preventing discharge of the product.
