In an article recently published by InsideHPC.com, Minnesota-based CPC (Colder Products Company), a provider of connection solutions for fluid handling, explained the correct connection terminations (either barbs for tubing or threaded joints) to ensure safe liquid cooling of high-performance computing (HPC) applications.

The article explained that quick-disconnect couplers with barbed terminations work best with flexible tubing and outlined several variations: triple barb, locking barb, and compression. “Barbed terminations grip the inside of tubing by expanding over the hose barb termination and then relaxing to its original diameter, creating a leak-free connection,” the article said.

Threaded port connections were a second option, particularly for machined ports in the liquid cooling loop. The different threaded terminations include SAE straight thread O-ring (ORB), NPT (National Pipe Thread), G/BSPP (British Standard Pipe Parallel), and R/BSPT (British Standard Pipe Taper).

The article concluded, “All terminations mentioned above are available in quick disconnect (QD) couplings, which allow fast, secure, repeated connections and disconnections during service and use.”
