Alphacool HF G1/4 to 13mm (1/2 inch) Barb Fitting, Brass, Deep Black, 4-Pack (17615)

When building or maintaining a custom water-cooling loop, the smallest components often determine long-term reliability. The Alphacool 17615 hose connector sets itself apart by pairing a robust brass body with a deep black anodized finish, ensuring both mechanical strength and a clean, professional look. Unlike generic plastic fittings, this connector is machined from solid brass, providing excellent resistance to corrosion and physical stress. The integrated O-ring guarantees a leak-free seal at the G1/4 thread, while the barbed design securely grips soft tubing with an inner diameter of 13 mm (1/2 inch). This pack includes four identical connectors, making it convenient for multi-connection setups or as spare parts.

Highlights

• Precision-machined brass construction for durability and corrosion resistance
• Deep black anodized surface for a sleek, uniform appearance
• G1/4 standard thread compatible with most radiators, blocks, and reservoirs
• Barbed fitting for soft tubing with 13 mm (1/2 inch) inner diameter
• Integrated O-ring ensures a reliable, leak-free connection
• Straight design with compact dimensions: total length 25.5 mm, outer diameter 18 mm
• Pack of 4 pieces for multiple connections or replacements

In daily use

Installing the Alphacool 17615 is straightforward: screw the G1/4 thread into the component, then push the soft tubing over the barb. The barb profile is designed to hold the tubing firmly without the need for additional clamps, though clamps can be used for extra security. The anodized finish not only looks good but also provides a layer of protection against scratches and minor impacts. Because the connector is made of brass, it can handle the typical pressures and temperatures found in PC water-cooling loops without deforming or cracking. The straight design minimizes flow restriction, helping to maintain efficient coolant circulation.
