Alphacool Apex Grip conexão de compressão HardTube 13mm G1/4 cromado - pack de 6 14927

Custom-loop builders working with rigid tubing will appreciate the secure, leak-free connections these Alphacool Apex Grip fittings provide. Each chrome-plated brass fitting is engineered for 13mm outer diameter hard tubes, using a high-grip compression ring that locks onto acrylic, PETG, or metal tubing without slipping. The G1/4" threads screw into standard water cooling components, and the included O-rings ensure a tight seal under pressure. This set of six straight fittings is ideal for routing clean, parallel tube runs in mid-tower or full-tower cases.

Why choose it

The Apex Grip design uses a specially shaped compression ring that bites into the tube surface for exceptional retention, reducing the risk of tube pop-out even under vibration or thermal cycling. The chrome finish resists corrosion and complements nickel or silver-themed builds. With six fittings in one pack, you can plumb a CPU block, radiator, and pump/reservoir combo with a consistent look.

Ideal use cases

• Building a custom water cooling loop with 13mm hard tubing
• Replacing worn or mismatched fittings in an existing loop
• Creating a show build with polished chrome accents
• Ensuring reliable connections in high-flow or high-pressure systems

Good to know

These fittings are designed for hard tubing only; do not use with soft tubing. Always deburr and chamfer tube ends before installation to avoid damaging O-rings. Hand-tighten the compression collar—do not use tools—to prevent cracking the tube. For best results, pair with Alphacool's 13mm hard tube or equivalent quality tubing.
