Alphacool's Eiszapfen (Icicle) fitting series is the high-end range of their proven fittings! With their high flow rate, precise shape, quality workmanship and intense colour, they fit perfectly into any system.

In normal systems, a normal reservoir acting as an expansion tank is usually sufficient to compensate for the pressures that occur. The components that are installed in a system are also pressure tested to at least 2 bar. But for users who have a lot of components in their loop, the extreme temperature difference between idle and operating mode can lead to very high pressures, and for some components it is advisable to release this pressure using a pressure relief valve.

This pressure relief valve can be easily screwed into any G1/4" connection and thus installed at any point in the loop. Some reservoirs, for example, have several openings where standard caps are used, so the valve can be inserted here. The G1/4" threaded connection is also very short, only 4mm, and allows for many other installation points in your loop. The seal attached to the underside offers additional security to keep your loop tight.
