Alphacool Apex Grip Compression Fitting 13/10mm G1/4 Black Set of 6 (14920)

For PC water cooling builders who demand a secure, leak-free connection between soft tubing and components, the Alphacool Apex Grip compression fitting set delivers a reliable solution. This pack of six straight fittings is engineered for 13mm outer diameter (1/2") and 10mm inner diameter (3/8") soft tubing, with a standard G1/4" thread that fits radiators, CPU blocks, GPU blocks, reservoirs, and pumps. The matte black brass construction with EPDM O-rings ensures corrosion resistance and a tight seal, while the screw-on installation makes assembly straightforward. Whether you are planning a new loop or upgrading an existing one, these fittings provide the consistent performance needed for daily use.

Why choose it

The Apex Grip fittings are built to last, with a robust brass body that resists corrosion and a matte black finish that complements any build. The compression design grips the tubing firmly, minimizing the risk of leaks even under pressure.

With six fittings in each pack, you have enough to connect multiple components, and the consistent quality ensures a professional-looking loop.

Ideal use cases

• Custom water cooling loops in desktop PCs
• Replacing worn or leaking fittings in existing systems
• Building a new loop with 13/10mm soft tubing
• Adding extra components like an additional radiator or GPU block

Good to know

These fittings are designed for use with soft tubing only; do not use with hard tubing. Ensure the tubing is cut squarely and pushed fully onto the barb before tightening the compression ring. Hand-tighten firmly, but avoid over-tightening to prevent damage. The G1/4" thread is the standard for PC water cooling, making these fittings compatible with most components on the market. Always leak-test your loop for at least 24 hours before powering on the system.
