Alphacool's Eiszapfen Connector Series is the high-end execution of these tried-and-true connectors!Every requirement you could have of a connector is met with this series: highflow, form, processing and colour. A refusal to compromise in development and production has made the Eiszapfen series into what it is. Components are available in brilliant chrome or a deep, matte black, which will fit excellently into any system.A special procedure binds the outer coating firmly to the surface, improving the longevity of the intense colour and preventing any chipping or peeling of the coating. Every connector now has the Alphacool logo, which along with their distinctive shape makes them unmistakable!The connecting nut's slanted corners allow the O-ring to be pressed firmly against the HardTube, ensuring it sits even more securely than before. This allows for greater safety in transport.Anyone looking for colourful options has them: the O-rings in the shipment come in three colours. With the available UV-light option, these will even light up in the corresponding colour.Model: HardTube Socket 16mmThis connector has a ¼” external screw thread on one side. The other side fits HardTubes with an external diameter of 16mm.
