Barrow Hardtube TDWG-14 14/12mm 90° Nickel rigid coolant pipe fitting

Barrow Hardtube TDWG-14 is a 90° rigid coolant pipe fitting designed for 14/12 mm hardline tubing with a nickel finish. It provides a precise, angled connection for 14 mm outer / 12 mm inner hard tubing used in custom PC liquid-cooling loops, enabling clean routing of coolant around tight corners and helping to maintain a compact and orderly loop layout.

Advantages

The nickel-plated surface offers corrosion resistance and a uniform metallic appearance that integrates with a wide range of cooling components. The fitting is engineered for a tight, consistent joint with 14/12 mm hard tubing, reducing the need for complex bending and minimizing stress on adjacent segments. Its 90° angle simplifies the routing of coolant lines in confined spaces while maintaining predictable flow direction and system aesthetics.

Suitable for

• Custom PC liquid-cooling loops using 14 mm outer / 12 mm inner hardline tubing
• Routing coolant around tight corners or changes in direction
• Systems where a professional, uniform nickel finish is required

Key specifications

• Angle: 90 degrees
• Compatibility: hard tubing with 14 mm outer diameter and 12 mm inner diameter
• Material finish: nickel-plated

How to use

Prepare the hard tubing by cutting square and deburring the ends to ensure a snug fit. Slide the tubing into the fitting until fully seated, verifying alignment at the 90° junction. Secure the connection according to your loop assembly method (compression, O-ring seating, or adhesive as appropriate for your fittings and tubing). Check the route visually to confirm clearance from other components before completing the loop and performing the initial leak test.

Usage recommendations

Use with properly sized 14/12 mm hard tubing and compatible sealing methods. Ensure cuts are straight and free of burrs to maintain sealing surface integrity, and perform a pressure or leak test after installation. Avoid forcing misaligned tubing into the fitting to prevent damage to the fitting finish or the tubing end.
