The Alphacool Eiszapfen HardTube connectors are among the most popular HardTube water cooling connectors on the market. They are particularly characterized by their high quality workmanship and the triple sealing system.

High-quality coating

Alphacool uses an advanced chromating process to apply the color to the brass connection. This not only makes the color more uniform, it is also significantly more durable and resistant to external influences. The small Alphacool logo is lasered in and not printed on. This means that it cannot be removed by friction.

Triple seal

Tightness is essential for a water circuit. That's why Alphacool uses three sealing rings on these icicle connections to seal the HardTube. Two O-rings are integrated in the connection, while the third O-ring serves as a closure and is attached together with the HardTube. The connection is secured using the union nut. This not only provides triple security, but also increases the tensile strength of the HardTube. This means that it takes a considerable amount of force to pull the HardTube out of the closed connection.

Assembly

The union nut is removed along with the O-ring inside. The connection is then screwed onto any component with a G1/4" thread. The union nut is first pushed onto the deburred HardTube that you want to insert into the fitting, and then the remaining O-ring is put on. The whole thing is then pushed into the fitting as far as it will go. The last step is to screw the union nut onto the connection.
