Liquid cooling (Everis)

Everis LQ8

Everis LQ8 is the largest CPC LQ series: couplings with 1/2" flow for cooling loops that move a lot of coolant, such as rack manifolds or the connection to a CDU. The valve disconnects without drips even under pressure, redundant seals protect the connected joint over long periods, and an audible click confirms engagement. Bodies are chrome-plated brass with EPDM seals for water-glycol, pressure range is vacuum to 8.3 bar and temperature -17 to 115 °C. Terminations: 15.9 mm (5/8") locking hose barb, SAE-12 and G3/4 male thread.

Frequently asked questions

When should I choose LQ8 over LQ6?: When the loop needs more flow: LQ8 is sized for 1/2" flow, LQ6 for 3/8". The low pressure drop keeps pump effort down.
Can LQ8 be disconnected under pressure?: Yes. Both halves shut on disconnection and nothing drips, so servers or manifolds can be swapped without draining the cooling loop.
Which coolants are intended?: The EPDM seal is designed for common water-glycol mixtures.
What is the locking hose barb for?: It holds reinforced tubing without an extra clamp. For a threaded joint choose SAE-12 or G3/4 male thread.
