Black 90-degree rotatable G1/4 compression fitting for 13mm hard tube

Alphacool

Alphacool Eiszapfen 13mm 90° rotatable G1/4 compression fitting Black

SKU CH-4M7Q-3A14M

A 13 mm hard-tube compression fitting with a 90° bend and rotatable G1/4 thread for flexible loop routing

  • Product typeFittings
  • 90° rotatable design simplifies tube routing in tight spaces
  • G1/4 thread fits 95% of water-cooling components directly
  • 13mm hard-tube compression seal locks acrylic or brass securely
  • Durable coating process resists chipping and preserves colour over time
  • Slanted union-nut corners press O-ring firmly for transport-safe connections

Precision 13 mm 90° fitting

This G1/4 compression fitting joins 13 mm acrylic or brass hard tube at a right angle. The rotatable threaded side lets builders align the connection without stressing the tube run. It is aimed at custom-loop builders who need a clean 90° turn in tight routing spaces.

Rotatable thread eases assembly

The 90° bend removes the need for extra hose length or awkward bends. Because the G1/4 thread rotates freely, the fitting seats cleanly against blocks, radiators or distribution plates. A slanted union nut presses the O-ring firmly against the tube for a secure seal during transport and daily use.

Coating resists chipping under load

A specialised surface treatment bonds the matte black finish to the metal, preventing peeling when the loop is pressurised or thermally cycled. The high-flow internal profile maintains consistent coolant velocity through the bend. Builders needing straight runs or larger tube diameters will need different fittings.

Questions about this item

How do I install the 13mm 90° rotatable G1/4 compression fitting onto a hard tube?

Slide the union nut and O-ring onto the 13mm acrylic or brass tube, insert the tube fully into the fitting body, then tighten the nut by hand plus a quarter turn with a spanner; the slanted nut corners seat the O-ring securely, and the rotatable G1/4 base lets you align the 90° bend before final tightening.

What maintenance or replacement will the fitting need over time?

The bonded matte-black coating resists chipping, so only the internal O-ring may degrade; inspect it during loop drains and replace with a standard 13mm compression O-ring if it shows flattening or cracking.

What is the first limit I will hit when running this fitting under sustained flow?

The 90° bend and 13mm internal diameter set the flow restriction; it becomes the bottleneck before the G1/4 thread or rotatable joint, so size your pump head pressure accordingly.
