Alphacool quick disconnect fitting ES BLH1A push-in male AG chrome, model 13878

Alphacool quick disconnect fitting ES BLH1A push-in male AG chrome, model 13878 is a chrome-plated push-in male connector engineered for liquid cooling loops in desktop PCs. The fitting enables rapid tool-free connection and disconnection of tubing, providing a compact, push-to-connect interface that helps simplify maintenance and upgrades in custom and modular cooling systems. Its chrome finish and push-in mechanism are designed to deliver a reliable, low-profile join that supports frequent servicing without compromising the integrity of the coolant loop.

Advantages

The push-in design offers quick, tool-free operation and a secure mechanical hold that reduces downtime during system changes. The chrome surface provides corrosion resistance and a neutral appearance that integrates with a variety of cooling components. The fitting is engineered for leak-resistant performance under typical PC water-cooling conditions and for repeated mating cycles, allowing reliable reconnection after maintenance or component swaps.

Suitable for

• Tool-free maintenance and quick tubing replacement in custom PC liquid cooling loops
• Modular cooling setups where components are frequently swapped or upgraded
• Systems requiring reliable, low-profile male push-in connectors for coolant lines

Key specifications

• Connector type: male push-in (push-to-connect) with external thread interface
• Finish: chrome-plated metal for corrosion resistance and visual consistency
• Intended use: liquid cooling loops for desktop PC applications
• Operation: tool-free connection and disconnection for tubing lines
• Serviceability: designed for repeated mating and maintenance cycles

How to use

Ensure the cooling loop is depressurized and the system is powered off before disconnecting or installing the fitting. Insert the tubing straight into the push-in male end until it seats fully; confirm a secure engagement by a gentle pull. When disconnecting, follow the manufacturer's recommended release procedure to prevent fluid spill—this typically involves operating the push-to-release mechanism while supporting the tubing. After any service, inspect connections for correct seating and perform a leak test before returning the system to normal operation.

Recommendations

Use compatible tubing size and material specified for PC liquid cooling to maintain sealing performance. Avoid excessive bending or strain at the joint and minimize exposure to aggressive coolants not intended for copper- or chrome-plated fittings. Perform a pressure and leak check after installation and after any maintenance that involves disconnection.
