Alphacool HF G1/4 16/10mm Compression Fitting Deep Black Six Pack

High-flow compression fittings

The Alphacool HF G1/4 16/10mm compression fittings are built for custom water-cooling loops that demand a large inner diameter. Each straight screw fitting accepts tubing with a 16 mm outer diameter and a 10 mm inner diameter. The G1/4 thread on the component side fits 95% of standard water blocks, radiators and reservoirs. Six fittings are supplied in a single pack, covering the typical port count for a CPU and GPU loop.

Deep Black finish and brass construction

A chromatised Deep Black coating is bonded to the brass body to resist peeling and maintain colour intensity over time. The straight design keeps tubing runs clean and simple without adding bulk. No moving parts or seals beyond the standard compression rings mean there is nothing to wear out or generate noise. Power draw is zero and the fittings add no thermal load to the system.

Sustained loop integrity

Under continuous pump pressure the compression rings maintain a reliable seal on 16/10mm tubing without retightening. The generous inner bore preserves flow rates during extended gaming or rendering sessions, preventing the restriction that smaller fittings can introduce. The six-pack quantity matches common dual-block builds so the loop can be completed without ordering extra parts. Builders using smaller tubing or angled connections will need different fittings.
