G1/4" to 3/8" Barb Fitting 6-Pack

This set provides six G1/4" male-thread to 3/8" inner-diameter barb connectors for custom desktop water cooling loops. Each fitting is machined from brass with a black chrome finish and includes an O-ring for a watertight seal. The pack suits builders assembling or maintaining a soft-tube system that uses standard G1/4" component ports. It is not for anyone needing hard-tube compression fittings or a different thread standard.

Installation and Common Issues

The barb slips over 9-10mm ID soft tubing and secures with a standard compression ring or clamp. The G1/4" thread engages component ports with a 5mm thread depth, while the 11mm barb OD and 15mm barb length give a firm grip. Leaks usually come from missing the O-ring, insufficient tubing insertion, or an overtightened clamp that cuts the tube. The 25mm overall length fits most block and radiator ports without clearance problems.

Critical Specification

The decisive figure is the 3/8" (9-10mm) inner-diameter barb size; it must match your soft tubing ID exactly. The G1/4" male thread is the other fixed interface — confirm every target component uses that port standard. If your tubing or ports differ, these six fittings will not work.

Questions about this item

How can I verify the fittings are sealing correctly after installation?

Pressure-test the loop and inspect each G1/4" thread O-ring for drips; the 11 mm barb OD and 15 mm barb length should sit fully inside 9-10 mm ID tubing with no gaps.

What comes in the package and is anything else required?

Six black chrome-plated brass G1/4" to 3/8" barb fittings are included; clamps or compression rings for the 9-10 mm soft tubing must be purchased separately.

Which version should I choose for my loop?

The single model D-BBT-3F-Black-6 supplies six identical G1/4" male to 3/8" ID barbs with 5 mm thread length and 25 mm overall length, covering standard desktop water-cooling blocks and radiators.
