Six-piece G1/4" barb set

This pack contains six G1/4" male-thread to 3/8" inner-diameter barb fittings finished in silver chrome. They are made from brass for corrosion resistance and include an O-ring on each thread for a watertight seal. The fittings suit custom liquid-cooling loops that use soft tubing.

Replaces mismatched or worn barbs

Swap these in when existing connectors leak, corrode or use a different thread standard. The 11 mm barb outer diameter and 15 mm barb length match common 9–10 mm ID soft tube, so the upgrade is worth it when you need a uniform, reliable seal across the loop.

Fits standard G1/4" ports

Each fitting threads into any component with a G1/4" female port such as radiators, blocks, reservoirs or pumps. The 5 mm thread depth and 25 mm overall length keep the profile short, freeing space around tight bends. You supply the soft tubing and clamps or compression rings to complete each connection.

Questions about this item

Will these 11mm OD barbs clear the 15mm barb length inside my reservoir ports?

The barb outer diameter is 11mm and the barb length is 15mm, with a 5mm G1/4" thread and 25mm overall length; measure your port depth to confirm the 15mm barb section fits.

Do I need PTFE tape on the 5mm G1/4" threads, or is the O-ring enough?

The included O-ring provides the seal; hand-tighten the 5mm G1/4" thread until the O-ring compresses, then add a gentle quarter-turn with a wrench — over-tightening damages the O-ring.

When should I replace the O-rings on these silver chrome brass fittings?

Inspect the O-rings whenever you drain the loop; replace them if they feel hard, show cracks, or after two to three years of continuous use to maintain a watertight seal.
