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 expansion fitting which is designed for connecting a variety of different components in a water-cooling loop and whose textured surface makes installation a breeze. The adapter comes with two male 1/4\" threads and comes in black anodised brass. The threads are equipped with a Viton O-ring to ensure a watertight fit.
