Six chrome compression fittings for custom loops

This pack contains six Alphacool HF compression fittings in a chrome finish. Each fitting accepts tubing with a 3/8 inch inner diameter and 5/8 inch outer diameter and connects via a standard G1/4 thread. The set suits builders assembling a custom water-cooling loop who want a coordinated metallic appearance.

High-flow bore maintains rates under sustained

The internal geometry is designed for high flow, reducing restriction so coolant moves freely even during prolonged, heavy thermal loads. A chromatising process bonds the chrome layer to the brass body, preventing peeling or colour loss after months of continuous operation and temperature cycling.

Verify G1/4 ports and 3/8" ID × 5/8" OD tubing

Confirm that every component in your loop — radiators, blocks, reservoirs and pumps — provides G1/4 threaded ports. Ensure your tubing matches the 3/8 inch inner diameter and 5/8 inch outer diameter exactly; mismatched sizes will not seal. No other thread standard or tubing dimension is compatible with these fittings.

Questions about this item

Will the chrome finish on these G1/4 compression fittings hold up after months of continuous coolant flow and heat?

The chrome layer is bonded to the brass body during chromatising, so the colour stays intense and will not peel even with constant liquid contact and system temperature cycles.

What tubing dimensions must I already have for these six fittings to seal correctly?

You need tubing with a 3/8 inch inner diameter and 5/8 inch outer diameter; the G1/4 threads then screw into standard water-block, radiator or reservoir ports.

Can I mix these chrome fittings with older nickel-plated or brass G1/4 parts already in my loop?

Yes — the G1/4 thread pitch is universal, so they thread directly into existing components, and the sealed compression design prevents galvanic contact between dissimilar metals.
