With the "Eisbaer" Quick-Connect Extension Kit, expanding an "Eisbaer" or "Eiswolf" GPX-Pro cooler loop with additional components is simple. For example, it's easy to add another radiator, an additional cooler or any other components. The kit consists of two 32cm-long hoses in 11/8 format, encased in anti-kink springs. This prevents bending in the hoses, and thereby prevents interruptions to the flow of water. Safety is our top priority. Two ends have 90? angled pieces, pre-installed on the hoses. The only thing you need to do is screw these into the corresponding G1/4" threads. On the other end are the ends of two quick-release safety locks from the Alphacool HF series, just like the ones found on the "Eisbaer" or "Eiswolf". That means all you have to do is open the quick-release locks on the "Eisbaer" or "Eiswolf" and screw them together with the corresponding parts in this kit and an additional product for extension, and your loop is complete - after it's been filled, of course.
