Alphacool HT 13mm HardTube Fittings

The Alphacool HT compression fittings provide secure G1/4 connections for 13mm outer-diameter hard tubes. Each chrome-plated fitting uses dual O-rings and a protective plastic disc to ensure a reliable seal. The knurled union nuts allow straightforward hand-tightening, while an 8mm Allen key secures the base. This six-pack supplies enough fittings for a typical custom loop build.

Builders using 13mm rigid tubing

These fittings suit builders assembling custom water-cooling loops with 13mm plexi or brass tubes who need a chrome finish. They are not intended for soft tubing, push-fit installations, or metric thread standards other than G1/4. Buyers requiring angled or rotary adapters, different tube diameters, or a black finish should select alternative models.

Verify tube diameter and thread compatibility

Confirm that your hard tubes measure exactly 13mm outer diameter and that all components in your loop use G1/4 threads. Check available clearance around each port to accommodate the fitting body and union nut. Ensure you have an 8mm Allen key for final tightening of the fitting base during assembly.

Questions about this item

What tube diameter do I need to use with these 13 mm compression fittings?

They are designed for hard tubes with a 13 mm outer diameter, whether plexi or brass.

Will the G1/4 threads on these fittings match the ports on my existing water blocks and radiators?

Yes, the G1/4 thread is the standard size used on almost all custom-loop components.

How can I confirm each fitting is sealed properly after I tighten the union nut with an 8 mm Allen key?

Pressurise the loop and watch for drips; the dual O-rings and protected seating should give a completely dry joint.
