13 mm HardTube 90° Elbow

The Alphacool 1011862 is a compression fitting built for 13 mm outer-diameter hard tubing made from acrylic, brass, borosilicate glass or carbon. It lets custom-loop builders make a clean ninety-degree turn without adding flexible hose. The Deep Black finish matches other components in the same colour series.

Knurled compression collars

Knurled collars give a secure grip on hard tubing and can be tightened by hand or with light tool assistance. The ninety-degree elbow routes tubing close to blocks, radiators or distribution plates where straight fittings would not fit. A new application process protects the Deep Black coating from fading or peeling over time.

Single fitting in the box

The package contains one elbow fitting ready for installation. Alphacool branding on the body and collars adds a consistent visual detail across the loop. The fitting is designed to work with Alphacool Plexi brass tubes and other compatible 13 mm hard tubing materials.

Questions about this item

Does the G1/4 thread on the 1011862 elbow limit flow compared to larger fittings?

The G1/4 thread is standard for custom loops and does not restrict flow in typical builds; the 90° bend adds minimal resistance compared to straight runs.

What tube outer diameter and wall thickness does the 13 mm compression fitting require?

It accepts any 13 mm OD hard tube — acrylic, brass, borosilicate glass or carbon — with standard wall thicknesses used in PC water-cooling.

Which step do builders most often get wrong when installing this 90° compression elbow?

Forgetting to chamfer and deburr the tube end before insertion; sharp edges can cut the O-ring and cause leaks once the collar is tightened.
