Alphacool HT 13mm HardTube 90° Elbow

This chrome compression fitting connects 13mm outer-diameter hard tubes at a right angle. It suits builders creating custom liquid-cooling loops with acrylic, brass, borosilicate or carbon tubing. The knurled collars provide secure grip for leak-free joints in high-end workstation or enthusiast builds.

Installation notes and common pitfalls

Push the tube fully into the fitting until it seats against the internal stop, then hand-tighten the knurled collar; no tools are required. The most frequent error is cutting the tube end unevenly or leaving burrs, which prevents a proper seal and causes drips under pressure.

Capacity and headroom

One 90° elbow redirects a single 13mm tube run without restricting flow in typical custom loops. It cannot join tubes of a different diameter, nor does it replace straight couplings or angled rotary adapters when the layout demands those geometries.

Questions about this item

How can I verify the 90° elbow is seated correctly after installing 13mm hard tube?

The knurled compression collars should sit flush against the tube with no visible gap and the chrome finish should show no deformation once the fitting is tightened by hand plus a quarter turn.

What comes in the package and do I need extra collars or tools for 13mm acrylic or brass tube?

The box contains one 90° elbow fitting with pre-installed knurled collars; no additional collars or special tools are required for 13mm acrylic, brass, borosilicate or carbon tubes.

Should I choose the Chrome or Deep Black version for a build using Alphacool Plexi brass tubes?

Both finishes use the same new application process that resists fading; select Chrome for a bright metallic accent or Deep Black for a stealth look — either matches the Plexi brass tube series.
