Brass G1/4 Compression Fittings

This pack contains six G1/4-thread compression fittings machined from brass with a black chrome finish. They connect 10 mm inner-diameter by 16 mm outer-diameter soft tubing to water-blocks, radiators, pumps or reservoirs that accept a standard G1/4 port. The embedded O-ring creates a liquid-tight seal without requiring clamps or tools beyond hand tightening. Each fitting measures 1.18 in by 1.18 in by .79 in and the set weighs 5.29 oz.

For Custom Loop Builders Using 10x16 mm Tubing

These suit builders assembling a custom open-loop cooler who have chosen 3/8 inch ID, 5/8 inch OD PVC or similar soft tube and need a black aesthetic. They do not suit anyone using hard acrylic or PETG tubing, nor systems that rely on push-to-connect or barbed fittings without a compression collar. Builders whose components use a thread other than G1/4 will need different adapters.

G1/4 Thread Compatibility Is The Deciding Spec

Every component in the loop — water-block, radiator, pump top, reservoir — must provide a female G1/4 port for these fittings to screw into. If any part uses a different thread such as NPT, M10 or a proprietary size, these six fittings cannot be installed without additional adapters that are not included.

Questions about this item

What thread size and tubing dimensions does this fitting need to match?

Each fitting uses a G1/4" thread and is made for soft tubing with a 3/8" inner diameter and 5/8" outer diameter (10×16 mm).

How do you install the fitting and which step is often missed?

Slide the compression nut and ring onto the tube, push the tube fully over the barbed base until it seats against the embedded O-ring, then tighten the nut by hand plus a quarter turn with a wrench; the step often missed is verifying the tube is fully seated before tightening.

What maintenance or replacement will these fittings need over time?

The embedded O-rings can degrade or flatten after repeated disassembly or long-term coolant exposure; keep spare O-rings on hand and replace them whenever a fitting is removed or if a slow seep appears at the seal.
