Dry Disconnect Cam and Groove CouplingsDry Break or dry disconnect cam and groove couplings are designed to prevent spillage during connection or accidental disconnection. These couplings are beneficial in petroleum and chemical applications where a spill can be costly, add downtime, and can be an environmental hazard. A spring loaded sealing device snaps closed automatically if the valve becomes disconnected with the poppet open. These coupling sets, also known as Bayloc, incorporate the ease of a cam and groove coupling with the security of a dry disconnect. Loading hoses can be disconnected without draining, without of product, saving time and minimizing spills. Stainless steel or aluminum coupling bodies are available, both types have stainless internals and handle (SS /brass internals on aluminum male adapter).
