Alphacool 17643 liitin messinki musta 17 mm × 17 mm × 21 mm

Alphacool 17643 is a brass ES compression fitting with a 1/4" thread, designed for use with tubing of 8/5 mm inner/outer dimensions. The fitting has a black finish and compact dimensions of 17 mm × 17 mm × 21 mm, intended for installation in computer cooling loops for servers and workstations.

Advantages

The brass construction offers corrosion resistance and mechanical strength while the ES compression design provides a secure seal for soft tubing. Its 1/4" threaded connection and compact form factor simplify integration into tight cooling setups. The black finish reduces visible reflections and matches typical PC cooling components.

Suitable for

• Server and workstation water-cooling loops
• Compact PC builds with limited space

How to use

Ensure the tubing is clean and cut squarely, then slide the compression sleeve over the tube end.

Hand-tighten and finish with a small turn using an appropriate wrench if required to achieve a leak-free joint. Verify alignment and clearance inside the case before final tightening.

Recommendations

Use the fitting with soft 8/5 mm tubing intended for liquid-cooling systems; check for leaks after initial fill and periodically during operation. Avoid excessive torque on the thread to prevent damage to the fitting or port.
