But what is an L connector needed for? There are two main applications. You can avoid bending your hard tubes and use L connectors or other Alphacool Eiszapfen adapters for all angles. This changes the overall look of the water cooling system. However, there are also situations where a 90° angle is required, but the space is so tight that it cannot be achieved with a manually bent hard tube. An Eiszapfen L connector can be the solution here. Double O-rings? Like all Eiszapfen fittings, Alphacool also uses a double O-ring system for the L connector. This significantly increases the tightness compared to other systems with only one O-ring. Material and coating? The Alphacool Eiszapfen L connector is made entirely of brass. Alphacool fundamentally relies solely on copper and brass products to prevent chemical reactions with other materials. The so-called chromating process is used for the coating. This ensures that the coating is firmly bonded to the brass, preventing it from chipping off. The Alphacool Eiszapfen L connector reflects all the positive features of all Eiszapfen fittings and offers the highest quality and functionality, combined with high safety.
