Everis BLQ4 is a CPC blind mate quick disconnect for rack-mounted liquid cooling, built to stay connected for long periods. Body and insert engage axially as the sled slides in and disconnect without dripping, even under pressure. Bodies are chrome-plated brass with EPDM seals, with G1/4, G3/8 (BSPP) or SAE male threads from 1/4" to 1/2", rated from vacuum to 8.3 bar at -17 to 115 °C.

How to choose Everis BLQ4
What matters when choosing: properties, comparison and typical applications.
Selection criteria
| Criterion | This series | Note |
|---|---|---|

| Termination | G1/4, G3/8 (BSPP), SAE 1/4", 3/8", 1/2" | G threads for European parts, SAE for US-style manifolds. |
| Body | Chrome-plated brass | For long-term and repeated use. |
| Seal | EPDM | For water-glycol mixtures. |
| Pressure | Vacuum to 8.3 bar | The BLQ2 is rated up to 13.8 bar. |
| Temperature | -17 to 115 °C | Applies to the EPDM version. |
Frequently asked questions
- What is the BLQ4 designed for?
- For rack cooling loops where sleds connect automatically when inserted. The friction-free valve is built for long periods in the connected state and for frequent connecting and disconnecting.
- Which thread should I choose?
- That depends on the mating part. G1/4 and G3/8 (BSPP) fit components with G threads, the SAE versions fit manifolds with SAE ports.
- What if the sled is not fully inserted?
- The BLQ4 tolerates axial offset and the valves still open to full flow. Redundant seals add protection against leaks.
- Where is the BLQ4 used in a data center?
- On rack manifolds and server sleds that connect to the liquid cooling loop automatically when pushed in. Because the coupling disconnects without dripping, components can be swapped without draining the cooling loop.
