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

This set contains twelve silver chrome fittings that convert a standard G1/4" male thread to a 3/8" inner diameter barb. They are built from brass and copper for corrosion resistance inside custom desktop liquid cooling loops. The pack suits builders who need multiple identical connectors for a single project.

O-Rings and Precise Dimensions

Every fitting ships with an installed O-ring that creates a watertight seal at the G1/4" thread. The barb measures 11mm outer diameter and 15mm length, while the thread engages 5mm for a total length of 25mm. These tolerances remove guesswork during assembly and help prevent leaks.

Soft Tubing Inner Diameter

The barb accepts 910mm inner diameter soft tubing, so the tubing size decides if this part fits your loop. Buyers using smaller or larger bore tube cannot use these connectors. No other specification limits compatibility.

Questions about this item

Will the O-rings on these G1/4" fittings need periodic replacement?

The package includes O-rings for the initial seal; inspect them during loop maintenance and replace if they show wear or hardening.

What is the maximum soft-tube inner diameter these 3/8" barbs can accept?

The barbs are designed for 9–10 mm inner diameter soft tubing, matching the 3/8" specification.

How much heat do the brass fittings add to the loop during continuous operation?

Brass fittings are passive components; they transfer negligible heat and do not raise coolant temperature under normal load.
