Connecting together individual components when water-cooling requires the correct types of connectors as well as a sufficient number of them. Failing to purchase the correct fittings or purchasing too few of them can make installation a slow and frustrating experience, as well as slowing down the process of getting your new system up and running. This is a straight, black extender fitting that is designed for connecting two graphics cards\' water coolers. To this end it is adjustable from 16 mm to 22 mm. Equipped with two male 1/4\" threads, this extender consists of black anodised brass and comes with two O-rings made from Viton to ensure a watertight loop.
