Minimal-Spill Quick-Disconnect Hose Couplings for Coolant



Reduce the risk of spills near electronics when connecting and disconnecting liquid cooling lines. Also known as double shut-off couplings, these couplings have a shut-off valve on both sides that stops the flow of coolant if they’re separated. Often used to connect servers to a cooling manifold in data centers, they comply with the performance specifications of OCP (Open Computing Project). To avoid mixing up your lines, choose blue couplings for cold supply and red couplings for hot return. A complete coupling consists of a plug and socket or two adapters (all sold separately).
Install plugs on manifolds and servers. They’re also known as nipples. Attach sockets to either end of a hose to connect your manifold to each server. To connect, push the plug into the socket until you hear a click. To disconnect, slide the sleeve on the socket forward until the plug is ejected.
UN/UNF (SAE Straight) threads are also known as O-ring boss threads.
BSPP male threads have a gasket to protect against leaks.
