Alphacool 13024 HF Compression Fitting G1/4 to 13/10mm (3/8“ID x 1/2”OD) Soft Tube - Deep Black

Leak-free connections are the backbone of any custom water cooling loop, and a poorly sealed fitting can spell disaster for your entire system. The Alphacool 13024 compression fitting addresses that risk head-on, providing a secure, tool-free connection between G1/4" threaded components and soft tubing with a 3/8" inner diameter and 1/2" outer diameter (10mm x 13mm). Machined from solid brass and finished in a deep black matte coating, this fitting is built to withstand the pressure and temperature cycles of high-performance PC cooling. Its straight design and high-flow internal geometry minimize restriction, while the integrated O-ring ensures a reliable seal without the need for clamps or adhesives. Whether you're building a new loop or upgrading an existing one, this fitting delivers the confidence that your coolant stays where it belongs.

Who is it for

This fitting is ideal for PC enthusiasts, overclockers, and system builders who demand both performance and aesthetics from their water cooling setup. It is particularly suited for users working with soft tubing in standard sizes, such as PVC, EPDM, or silicone, and who need a dependable connection to radiators, CPU blocks, GPU blocks, pumps, or reservoirs. Its matte black finish complements a wide range of build themes, from stealthy all-black rigs to more colorful configurations where fittings should blend in rather than stand out.

Tips

When installing, ensure the tubing is cut cleanly and squarely to achieve the best seal. Slide the compression ring onto the tube before pushing the tube over the barb, then tighten the ring by hand until snug—do not overtighten, as this can damage the O-ring or deform the tube. For optimal flow, keep tubing runs as short and straight as possible, and consider using angled fittings only where necessary. Always leak-test your loop with distilled water for at least 24 hours before powering on your system.
