Alphacool's new quick couplers with the name "Eiszapfen" are the next block in the "Eis" series. High quality and impressive features makes any watercooling system back to a piece of high-quality and practical! A quick coupling is used everywhere where expandability, flexibility and cleanness play an important role. These compact couplings have a 3/8" thread on both sides. To use the standard 1/4" thread you need a adaptor from 3/8" to 1/4". By pulling down the outer ring these couplings can be disconnected. Both sides close immediately completely tight so that no water can escape. Thanks to the special N.D.S.L. Technology (no drip, no splash, no leak) a leak, drip or splash out of the water on opening the lock is excluded. By assembling again, both sides must click into each other audibly and shut themselves tightly by a double O-ring, which is simply compressed when plugged together. Likewise, the mechanism was designed for durability to ensure a secure connection even years. Many quick couplings usually also affect the flow rate. But Alphacool has found a way to resolve this issue. A high flow rate is maintained at these quick couplings! Alphacools quick couplers are available in two finishes. In deep black and fully chromed these add seamlessly on every system. Model: 17370
