Two-Pack G1/4" Soft-Tube Fittings

This pair of silver compression fittings connects 3/8" ID, 1/2" OD soft tubing to a standard G1/4" thread in a custom water-cooling loop. They are built from brass and copper with a chrome finish for corrosion resistance. The set suits builders assembling a new loop or extending an existing one. Each fitting weighs 1.76 ounces and measures .86 x .7 x .86 inches.

G1/4" Thread and 10×13 mm Hose Limit

The G1/4" UN thread is the only interface these fittings accept, so every block, radiator or pump port must match that pitch. Tubing must be exactly 10 mm inner diameter by 13 mm outer diameter (3/8" ID, 1/2" OD); larger or smaller hose will not seal. No adapter for other thread sizes or hose dimensions is included. The embedded O-ring provides the sole sealing surface, so surface finish on the mating port matters.

Hand-Tight Install With Leak-Test Step

Installation is a simple hand-tighten of the knurled collar onto the tubing and thread; no special tools are required. The most common issue is under-tightening, which leaves a microscopic weep path under pressure. Over-tightening can deform the soft tube and also cause leaks. The manufacturer stresses a full loop pressure test before powering the system to catch any seal failures.

Questions about this item

Should I pick the two-pack or look for a larger kit?

The product is sold as a two-piece pack; buy multiple packs if your loop needs more than two connection points.

What does the 0.86-inch dimension mean once the fitting is installed?

Each fitting measures 0.86 in long by 0.86 in wide by 0.7 in thick, so it adds that much length and bulk to every tube run.

The fitting uses a G1/4 thread — what tubing sizes does that actually support?

It accepts soft tubing with 3/8 in inner diameter and 1/2 in outer diameter (10×13 mm), sealing with the included O-rings.
