Alphacool pikaliitin ES, uros BLH1A integroidulla läpivientiliittimellä

The Alphacool quick release coupling ES, male BLH1A with integrated bulkhead fitting is a push-to-connect fluid connector designed for PC water-cooling systems. The component combines a male quick-disconnect coupling with a sealed bulkhead pass-through, enabling a hose or tube to be disconnected rapidly while maintaining a leak-resistant seal at the mounting point. It is intended for use in cooling loops where frequent maintenance, modular component changes or rapid reconfiguration are required.

Advantages

This coupling provides quick separation of tubing without the need to drain the entire loop, reducing downtime during maintenance or component swaps. The integrated bulkhead fitting ensures a stable, sealed mounting through a case panel, radiator or reservoir wall, minimising the risk of leaks at the penetration point. The design supports repeated connections and disconnections while preserving a secure fluid path and simplifies routing in compact or modular builds.

Suitable for

• PC water-cooling maintenance and component replacement
• Modular PC builds requiring frequent disassembly
• Routing coolant through panels, radiators or reservoirs
• Test rigs or temporary setups where fast disconnects are needed

Key specifications

• Type: Male quick release coupling with integrated bulkhead fitting
• Compatibility: Designed for use in liquid cooling loops for PCs
• Connection method: Push-to-connect quick-disconnect for hose or tube
• Sealing: Bulkhead provides a sealed pass-through for mounting surfaces
• Use case: Repeated connect/disconnect cycles for maintenance and modularity

How to use

Install the bulkhead fitting into the panel, radiator or reservoir opening and secure it according to the mounting hardware supplied or the host component's specification. Attach the compatible hose or tube to the male quick release coupling until it seats fully. To separate the connection, follow the coupling's release mechanism: press or pull the designated collar or button and withdraw the tubing or mating connector. When reconnecting, ensure both mating surfaces are clean and the coupling engages fully to restore a sealed fluid path.

Recommendations

Use hose or tubing that matches the coupling's intended inner diameter and material compatibility. Inspect seals periodically for wear and replace any damaged components before reusing. When performing maintenance, have absorbent material or a small container ready to catch residual coolant during disconnection to prevent spills. Verify tight seating after each reconnection and pressure-check the loop before normal operation.
