Chrome compression fittings for custom loops

This six-pack of Alphacool HF fittings uses a G1/4 thread and accepts tubing with a 3/8 inch inner diameter and 1/2 inch outer diameter. The chrome finish is bonded to the brass body through a chromatising process intended to resist peeling and maintain colour over time. They are aimed at builders assembling a hard-tube or soft-tube water-cooling loop who want a consistent metallic accent across multiple connection points.

Brass bodies with bonded chrome coating

Each fitting is machined from brass and finished in chrome using a surface treatment that fuses the layer to the substrate rather than simply plating over it. The compression design secures the tube by tightening an outer nut, which compresses an internal olive against the tubing wall for a leak-tested seal. The high-flow internal bore is sized to match the 3/8 inch ID specification, reducing restriction in dense loops with multiple blocks and radiators.

Verify thread standard and tube dimensions

Confirm that every component in your loop — blocks, radiators, reservoirs, pumps — provides a G1/4 female port before ordering. Measure your tubing to ensure it is exactly 3/8 inch ID and 1/2 inch OD; mismatched sizes will not seal correctly. No adapters or reducers are included in the pack, so plan the total fitting count for your complete loop layout.

Perguntas sobre este artigo

What thread standard do the Alphacool HF compression fittings use and what tube sizes do they accept?

The fittings use a G1/4 thread and accept tubing with a 3/8 inch inner diameter and 1/2 inch outer diameter.

What clearance is required to install these G1/4 compression fittings in a custom loop?

Each fitting needs a G1/4 threaded port and enough wrench clearance to tighten the compression nut onto 1/2 inch OD tubing.

How are the Alphacool HF chrome fittings installed and which step is often missed?

Slide the compression nut and olive onto the tube, push the tube fully onto the barb, then tighten the nut until the olive seals; the step often missed is fully seating the tube before tightening.
