Barrow Hardtube Fitting 14 mm with G1/4

Barrow hardtube fitting for 14 mm rigid tubing with a G1/4 thread in a silver finish. Designed for custom PC liquid cooling loops, this fitting provides a threaded G1/4 interface for secure attachment of 14 mm hardline pipes, allowing precise, leak-resistant connections and compact coolant routing. The metal construction and finish are intended to match or complement aluminium and chrome components commonly used in water-cooling builds.

Advantages

The fitting delivers a stable mechanical connection for 14 mm hardline tubes and a standard G1/4 threaded interface for compatibility with radiators, pumps, reservoirs and other water-cooling components. Its silver finish provides corrosion resistance and a neutral aesthetic that integrates with a wide range of builds. The design focuses on creating reliable, low-leak joints and tidy coolant runs without adding bulk.

Suitable for

• Custom PC water-cooling loops using 14 mm hard tubing
• Connecting reservoirs, pumps, radiators and blocks with G1/4 ports
• Retrofit or upgrade projects where threaded, compact fittings are required

Key specifications

• Compatible tube outer diameter: 14 mm hard tubing
• Threaded connection: standard G1/4 thread
• Finish: silver metal surface
• Material: metal construction suitable for liquid-cooling applications

How to use

Prepare the 14 mm hardline tube by cutting and deburring the end to ensure a square, smooth edge. Slide the tube into the fitting and tighten the threaded G1/4 connection to the corresponding port on the component; use appropriate torque to avoid over-tightening. Verify alignment to maintain tidy coolant routing, then pressure-test the loop or run a controlled leak test before full operation. Follow standard liquid-cooling assembly practices, including using compatible seals or O-rings where required.

Recommendations

Use a proper tube cutter and deburring tool to prevent seal failures. Apply moderate torque when tightening G1/4 threads and perform a pressure/leak test after assembly. Match the fitting finish with other visible components for a consistent appearance and select compatible O-rings or sealing materials suitable for your coolant.
