Alphacool's Enterprise Solutions series of new HF quick disconnect couplings are specifically designed for Alphacool TPV hoses. Thanks to a locking ring they have a very high tensile strength, which consists of a metal ring and claws with hooks in the hose. Furthermore, this quick release coupling, unlike others, uses screw caps. This prevents the closure simply opening up as a result of vibration or movement. The double seal guarantees maximum tightness. The closures are not only for safety, but also for longevity. Being made of nylon, they are extremely durable and can be easily used with copper and aluminum parts in the water cycle because nylon does not react with other materials.
