12-Pack G1/4" to 3/8" Barb Fittings

This set provides twelve brass connectors with a black chrome finish for custom liquid cooling loops. Each fitting bridges a standard G1/4" male thread to a 3/8" inner diameter barb, accepting 9-10mm soft tubing. They are built for desktop water cooling blocks and radiators.

O-ring seal and brass construction

The integrated O-ring creates a watertight seal at the threaded port while the barb grips the tube securely. Brass resists corrosion during sustained coolant circulation and the chrome finish adds further protection against oxidation over long operating periods.

3/8" barb for 9-10mm ID tubing

The 11mm barb outer diameter and 15mm barb length are sized specifically for 3/8" ID soft tube. Builders using larger 1/2" ID tubing or rigid acrylic pipe will need different fittings.

Questions about this item

How much power do these fittings draw when the loop runs all day?

These brass fittings are passive components; they draw no power and generate no heat themselves.

What tubing must I already have for the 3/8" barbs to seal?

You need soft tubing with a 9–10 mm inner diameter so the 11 mm barb OD and 15 mm barb length can grip securely.

Will the G1/4" threads work with the older radiator blocks I am keeping?

Yes, the 5 mm G1/4" male thread fits any standard G1/4" female port on legacy blocks or radiators.
