DeltaMate Rotary Fittings are water cooling connectors designed for the individual components of a custom water cooling loop. As expected from Thermal Grizzly quality, the rotary fittings are precisely machined from brass. Brass, as an alloy of copper and zinc, offers the advantage of being anodically compatible with other metals while being harder and more corrosion-resistant than copper. General information The sealing rings (O-rings) are made from highly elastic EPDM (ethylene propylene diene rubber), which is resistant to ozone and UV radiation. The robust design of the DeltaMate fittings allows for installation using an 8 mm hex key. The uniform outer diameter of all DeltaMate fittings ensures seamless integration of individual components. The DeltaMate Rotary - 45 degrees in black allows for modular combination with other DeltaMate Rotary and Extender Fittings due to its compact dimensions. The DeltaMate Rotary - 45 degrees has one male and one female G1/4" thread and offers a premium finish in the form of a black chromium plating that is also easy to clean. When using additional fittings, they mechanically lock the rotary joint together for maximum security. Properties Small dimensions allow modular combination with other DeltaMate Rotary and Extender Fittings. Can be used in pairs to create 14mm Offset Fittings or any angle between 0 degrees and 90 degrees. Elegant and minimal design integrates seamlessly with all DeltaMate fittings. Easy to install in tight places and SFF builds using an 8mm hex key.
