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.
Use adapters for supplying your manifold. They have a lever-activated shut-off valve, which must be closed for a coupling to be separated. To connect, push two adapters together with a quarter twist, then press the lever to open the valve and start the flow.
UN/UNF (SAE Straight) threads are also known as O-ring boss threads.
BSPP male threads have a gasket to protect against leaks.
Barbed fittings require a pinch clamp when used with pressures above 70 psi. When used below this pressure with our Coolant Hose for Electronics, no clamp is needed. The more you pull on these fittings, the tighter the hose will grip.

Coolant Hose for Electronics
- Temperature Range: -40° to 280° F
- Material: Peroxide-Cured EPDM Rubber
- Color: Black, Blue, or Red
- Compatible Hose Fittings: Minimal-Spill Quick-Disconnect Hose Couplings for Coolant
Blue for cold and red for hot—this hose is color coded so you won’t mix up your coolant supply lines. It’s also available in black. Use it in data centers to connect servers to a cooling manifold. Made of peroxide-cured EPDM, it withstands temperatures up to 280° F. The cover meets UL 94 V-0 for flame retardance.
When used below 70 psi, you don’t need a hose clamp to attach a coupling to this hose. The more you pull on the coupling, the tighter the hose will grip. For higher pressures, use a hose clamp.
