Barrow Mods THKN-3/8-B03 Gold G1/4 3/8"ID 1/2"OD 10x13mm Soft Tube Fittings

Fittings for 10x13mm soft tube

These gold-coloured compression fittings accept tubing with a 10 mm inner diameter and 13 mm outer diameter. Brass bodies with nickel plating provide corrosion resistance inside a custom liquid-cooling loop. Each fitting uses a standard G1/4 thread for connection to blocks, radiators or reservoirs. The hand-tight design allows assembly without specialised tools.

Sealing behaviour under constant pressure

The compression collar distributes clamping force evenly around the tube wall, maintaining a reliable seal while the loop runs continuously. Nickel-plated brass resists coolant additives and temperature cycles without degrading. Because the fitting is rated for the stated tube dimensions only, the joint remains stable during extended operation at typical loop pressures.

Compatibility checks before ordering

Verify that your tubing matches the 9.5 mm inner and 12.7 mm outer dimensions exactly; other sizes will not seal correctly. Confirm every component you plan to join exposes a G1/4 female port. Ensure you have enough fittings for each connection point in the loop, as this item is sold individually.
