G1/4 90° Revolvable Fitting

The Alphacool 13mm barbed fitting connects soft tubing with a 13mm inner diameter to any component using a standard G1/4 thread. Its 90° revolvable design lets the elbow rotate freely after tightening, simplifying tube routing in tight loops. A deep black chromatised finish bonds to the brass body for lasting colour.

Builders needing a single 90° connection

This fitting suits custom loops that require one right-angled joint for 13mm ID tubing. It does not serve builds using smaller or larger tubing diameters, nor does it replace straight or multi-angle adapters. Buyers needing quick-disconnect or compression-style seals should look at other fitting types.

Sustained flow with minimal restriction

The wide inner bore maintains high flow rates during continuous pump operation, reducing pressure drop across the elbow. The revolvable joint stays aligned under vibration and thermal cycling, preventing kinks that would throttle coolant movement over long runs.

Questions about this item

What tubing inner diameter must I already have for the 13 mm barbed end to seal properly?

You need soft tubing with a 13 mm inner diameter; the barbed end is sized for that exact bore and the included O-ring seals against the G1/4 port.

Will the 90° revolvable elbow clear a radiator port that sits close to a motherboard heatsink?

The fitting rotates freely after tightening so you can orient the 90° bend away from nearby components, but the overall height is fixed by the 90° geometry.

How can I confirm the Deep Black finish is correctly seated and leak-free after installation?

Tighten the G1/4 thread until the O-ring compresses, then run the loop under pressure; no coolant should appear at the thread or barb junction.
