Everis BLQ2 is the CPC blind mate coupling with 1/8" flow for rack-mounted liquid cooling. Body and insert are fixed to the sled and the rack and connect axially as the sled slides in, then disconnect without dripping, even under pressure. The body is chrome-plated brass with EPDM seals and a 1/4" SAE thread, rated from vacuum to 13.8 bar and from -17 to 115 °C.

How to choose Everis BLQ2
What matters when choosing: properties, comparison and typical applications.
Selection criteria
| Criterion | This series | Note |
|---|---|---|
| Design | Blind mate, valved body and insert | Engages axially without reaching the coupling by hand. |
| Flow | 1/8" | For lines with low flow rates. |
| Termination | 1/4" SAE thread | For manifolds and adapters with SAE ports. |
| Body | Chrome-plated brass | Robust for frequent connecting and disconnecting. |
| Seal | EPDM | For water-glycol mixtures. |
| Pressure | Vacuum to 13.8 bar | BLQ4 and BLQ6 are rated to 8.3 bar. |
| Temperature | -17 to 115 °C | Applies to the EPDM version. |
Frequently asked questions
- What does blind mate mean for the BLQ2?
- Body and insert are fixed in place, one on the sled and one on the rack. They align axially as the sled slides in, and the valves open to full flow even when the coupling is not fully engaged.
- Does the connection stay tight over long periods?
- The BLQ2 is built for long periods in the connected state. Redundant seals close the connection, and the friction-free valve also keeps contaminants and debris out.
- Which coolant is the BLQ2 suited to?
- The seals are EPDM, which suits water-glycol mixtures. For dielectric coolants with FKM seals, look at the LQ2.
- Where is the BLQ2 used in a data center?
- On rack manifolds and low-flow sleds that should connect to the cooling loop automatically when pushed in. Because the coupling disconnects without dripping, components can be swapped without draining the cooling loop.
