Marine Break-Away Couplings

Marine versions of Safety Break-Away Couplings are designed to be installed within lengths of hoses. The coupling is assembled with a length of hose attached to each side.

This coupling incorporates the same internal mechanism as our Industrial Coupling, with additional features that provide increased resistance to torsional and bending forces, particularly important when used in the unpredictable marine environment. Marine Safety Break-Away Couplings are designed to release by inline pulling.

Typical applications include ship to offshore platform, ship to ship product transfer and bunkering operations.
