G1/4" Compression Fittings for Soft Tubing

This 12-pack of black chrome finished brass fittings connects G1/4" threaded ports to 3/8" ID, 1/2" OD soft tubing in custom water cooling loops. The compression design uses embedded O-rings to create a secure, leakproof seal without requiring clamps or tools. Builders assembling a new loop or expanding an existing one will find the quantity convenient for multi-component configurations. These fittings are not suited for hard tubing or barbed hose connections.

Soft Tubing Dimensional Limits

The fittings accept only 10×13 mm (3/8" ID, 1/2" OD) PVC soft tubing; other inner or outer diameters will not seal correctly. Each fitting threads into a standard G1/4" port, so the host component must provide that exact thread pitch and depth. The compression collar and O-ring rely on the tubing's specific wall thickness to prevent blow-off under pressure. Loops using larger bore tubing, PETG, acrylic or push-fit connectors cannot use these parts.

Twelve-Pack Quantity Decides Suitability

The pack contains exactly 12 fittings, which typically covers a CPU block, GPU block, dual radiator, reservoir, pump and a few angled adapters in a single loop. Buyers needing fewer than six or more than twelve pieces must purchase multiple packs or seek individual units elsewhere. The fixed count also means the package weight of 0.66 pounds and dimensions of 5.46×3.9×0.98 inches are predetermined for shipping and storage planning. Builders with minimalist or exceptionally large loops should verify the count matches their bill of materials.
