Quick-Disconnect Fittings Built for High-Density AI Cooling
Leak-proof, corrosion-resistant, and easy to service during GPU rack swaps and maintenance. Engineered for uptime-critical liquid cooling environments in AI clusters and colocation facilities.
Quick-Disconnect (QD) fittings are essential for maintaining GPU liquid cooling loops without draining the entire system. Our QDs support tool-less maintenance, minimal fluid loss, and high pressure stability, making them ideal for direct-to-chip (D2C) and rear-door heat exchanger cooling architectures.

Use Cases
GPU Rack Servicing
Hot swap racks without full loop drains. Reduce service downtime by up to 80% during rack maintenance with tool-less connect/disconnect.
Manifold Connections
Connect distribution manifolds to rack-level coolant loops. High-flow QDs with ½" hose barbs and inline shutoff valves for reliable distribution.
CDU Maintenance
Enable fast service access to Coolant Distribution Units. Prevent coolant spills and GPU risk with dry-break design engineered for data center safety.
Lab & Test Cooling Rigs
Ideal for prototype and validation environments with frequent reconnects. Speed installs with tool-less operation and minimal fluid loss.
Colocation Build-Outs
Simplify moves/adds/changes across data hall expansions. Scalable in bulk — ideal for colo and hyperscale rollout with serialized labeling.
