Angled Adaptor for Tight Loops

The Alphacool Eiszapfen 45° G1/4 adaptor connects a male thread to a female thread, letting tubing turn sharply in cramped water-cooling layouts. It is built for builders who need a compact routing option without adding extra fittings. The brass body keeps the flow path open while the black coating resists wear. This part suits custom loops where straight runs are impossible.

Coloured O-Rings for UV Accents

Three coloured O-rings ship in the box and glow under UV lighting, giving a quick way to add visual contrast without separate purchases. The rings seat in the standard grooves so no extra tools or steps are required. Swapping colours takes seconds and does not affect sealing. Builders who prefer a single-tone look can simply use the fitted black ring.

Brass Construction With Durable Coating

The adaptor measures 21 x 20 x 21 mm and uses a special process that binds the matte black finish to the brass, preventing chipping or peeling during repeated assembly. Thread depth is 5 mm on both G1/4 ports, providing solid engagement with standard fittings. The 45° angle reduces stress on tubing bends near blocks or radiators. The Alphacool logo is machined into the body for identification.

Questions about this item

Will the G1/4 threads on the Alphacool Eiszapfen 45° adaptor need re-sealing or replacement over time?

The brass threads and included coloured O-rings are designed for long-term sealing; the coating process resists chipping, so routine re-sealing is not expected.

What is the first flow restriction I will hit when running coolant through this 45° G1/4 fitting all day?

The 45° bend and 21 mm length create the primary pressure drop; the high-flow internal profile minimises turbulence beyond that geometry.

How much heat does the brass body add to the loop when the pump runs continuously?

Brass conducts heat well, but the 21 x 20 x 21 mm mass is small; it reaches coolant temperature quickly and adds negligible thermal load.
