## Summary description

Barrow Hardtube Fitting 16 mm with G1/4" thread is a black compression-style adapter for 16 mm rigid (hard) tubing used in liquid cooling loops and custom PC watercooling systems. The fitting provides a secure sealed connection between tubing and G1/4" threaded components such as blocks, radiators, and reservoirs. Suitable for assembling and routing hardline coolant paths.

## Long description

Barrow Hardtube Fitting 16 mm G1/4" is a straight black compression fitting designed for 16 mm rigid (hard) tubing used in custom PC liquid cooling systems. The fitting features a G1/4" threaded connection that mates with water blocks, radiators, reservoirs and other G1/4" ports to create a watertight seal for coolant circulation. Its straight form factor assists in creating clean, linear runs of hardline tubing and in routing coolant paths within compact or windowed cases.
Advantages
This Barrow straight compression fitting provides a reliable mechanical connection and a leak-resistant seal for hard tubing systems, combining a compact profile with a standard G1/4" thread for broad compatibility. The black finish reduces visible reflections and matches common aesthetic schemes for modern builds. The compression mechanism is suitable for repeated installation and removal while maintaining consistent sealing performance when assembled to the correct torque.
Suitable for
 Custom PC liquid cooling loops using 16 mm hard tubing
 Connecting water blocks, radiators, reservoirs and pump-top components with G1/4" ports
 Creating straight hardline runs and tight routing paths inside cases
 Upgrading or replacing existing compression fittings in hardline systems
Key specifications
 Fitting type: straight compression-style adapter
 Tubing compatibility: designed for 16 mm outer-diameter rigid (hard) tubing
 Thread interface: G1/4" female/male threaded connection (standard PC watercooling thread)
 Finish: black
 Material: metal alloy with sealing elements (compressive seal)
How to use
Prepare the 16 mm hard tubing by cutting squarely and deburring the end to ensure a flat mating surface. Insert the tubing into the compression fitting until it seats fully against the internal stop, then tighten the compression ring by hand and finish to the appropriate snugness with a tool if required; avoid excessive torque to prevent deformation of the tubing or fitting. Thread the G1/4" connection into the target component and tighten to create a watertight seal. After assembly, perform a pressure or leak test of the loop before powering the system.
Usage recommendations
Use with tubing specifically specified as 16 mm outer diameter hard (rigid) tube. Ensure all mating threads use appropriate thread sealant or PTFE tape only where specified by the component manufacturer; do not overtighten fittings. When planning your loop, allow for thermal expansion and provide support where long straight runs could flex. Inspect seals and fittings periodically and re-test for leaks after maintenance or modifications.
