As data centers expand to handle AI, IoT, and edge computing, liquid cooling has become essential for maintaining performance and efficiency. But cooling reliability depends on more than just fluid—it’s about connections you can trust. That’s where CEJN’s OCP (Open Compute Project) couplers set the standard for liquid cooling distribution units (CDU) and direct-to-chip (DLC) applications.
At Summers Rubber Company, we deliver more than components—we provide the technical expertise, inventory, and custom assemblies that keep your cooling systems running at peak reliability.
Why CEJN OCP Couplers Are the Benchmark
- Universal OCP Design
CEJN couplers are built on open, modular standards. That means seamless interchangeability with OCP-compliant products across multiple vendors—no compatibility surprises. - LQC Screw-to-Connect
Engineered for CDU service, the LQC allows connections and disconnections under pressure (up to 5 bar). Stainless-steel construction and dual O-ring sealing ensure leak-free performance and durability. - Blind-Mate UQDB & BMQC
Tailored for Direct Liquid Cooling, these couplers are spill-free and self-aligning—even with tolerances of ±1 mm or ±5 mm / ± 2.7°. They enable tool-free hot-swaps without interrupting operations.

FAQs
What’s the difference between LQC and UQDB/BMQC couplers?
LQC is a screw-to-connect solution ideal for CDU service under pressure. UQDB/BMQC are blind-mate designs for DLC applications, allowing spill-free connections even with slight misalignment.
Can these couplers be serviced under pressure?
Yes. Both LQC and blind-mate options allow hot-swaps without depressurizing the system.
Does Summers Rubber build custom hose assemblies?
Absolutely—we fabricate hose assemblies tailored to your application specs in-house.
Are CEJN couplers interoperable with other brands?
Yes. Their OCP-compliant design ensures cross-brand compatibility and easy integration into existing systems.
