Frequently Asked Questions:
Q: What’s the difference between LQC and UQDB/BMQC couplers?
A: LQC models use a screw-type connection for CDU applications under pressure. UQDB and BMQC couplers are blind-mate connectors for Direct Liquid Cooling, allowing quick, spill-free swaps even with some misalignment.
Q: Can these couplers be connected or disconnected under pressure?
A: Yes. Both LQC and blind-mate styles are built for hot-swap use while systems are pressurized.
Q: Does 4-STAR Hose make custom hose assemblies?
A: Absolutely. We fabricate assemblies to your exact design, performance ratings, and coolant specifications.
Q: Are CEJN OCP couplers cross-brand compatible?
A: Yes—they meet OCP standards, so they work with any compliant manufacturer’s products.
