Liquid Cooling Connector FAQ
- Q: What are liquid cooling connectors used for?
- They connect cooling loops in data centers, EV battery thermal management, energy storage and industrial power electronics.
- Q: How do you ensure leak-free connectors?
- Sealing surfaces are machined to ±0.005mm and every connector is 100% leak tested by pressure-decay before shipment.
- Q: Which materials are used?
- Aluminum, stainless steel and brass, with anodizing or passivation for corrosion resistance.
- Q: Do you make custom connector geometries?
- Yes. We manufacture to customer drawings, including quick-disconnect, blind-mate and manifold connectors.
