G1/4" to 3/8" Barb Fitting

This Bitspower fitting connects soft tubing with a 3/8" inner diameter to components using a standard G1/4" thread. It is built from high-quality brass with a Silver Shining finish. The hidden O-ring design provides a secure seal inside the thread. This component is designed for custom water-cooling loops.

For 3/8" ID soft tubing builds

This fitting suits builders assembling a loop with 3/8" inner diameter tubing and G1/4" threaded ports. It is not for systems using hard tubing or tubing with a different inner diameter. Buyers needing a compression fitting instead of a barb should look at a different style. It also does not fit components with non-standard thread sizes.

5 mm thread length

The male G1/4" thread measures 5 mm in length, which determines how deep it seats into a waterblock or radiator port. Verify that your component's thread depth accommodates this measurement. The tubing side extends 15 mm for the barb connection. This specific dimension decides if the fitting clears obstacles or seats fully.

Questions about this item

What tubing inner diameter must I already have for this G1/4" to 3/8" barb fitting?

You need soft tubing with a 3/8" inner diameter; the barb side is sized for that exact bore.

Will the 5 mm thread length engage properly in my existing G1/4" water-block ports?

Yes, the 5 mm G1/4" thread is the standard depth used by most water-blocks and radiators.

How can I confirm the hidden O-ring is sealing after I tighten the fitting?

Pressurise the loop and watch the joint — no coolant should appear at the thread or barb junction.
