Make your liquid cooled system more practical and easier to maintain with your new Eiszapfen quick release fittings. With this fitting you can combine different versions of the quick-release couplings. There are versions with bulkhead connections, with G1/4" external thread or with G1/4" internal thread. This allows you to create the best solution for your own project. No drip - no splash - no leak Alphacool uses the proven N.D.S.L. technology (no dripping, no splash, no leaking) for its Eiszapfen series. This leaves you the freedom to decouple in your running system without dripping. Turn your normal water cooling system into a high flow system! The Eiszapfen quick release fittings are separated by simply pulling the connecting ring. The Alphacool Eiszapfen quick-release fasteners are available in various designs, but can all be combined with each other. A quick-release fastener always consists of two fittings. You always need the right counterpart to create a complete quick release fastener. With this product you only get 1 half of the quick-release fastener.
