Connecting individual water-cooling components requires extra attention to detail in regards to choosing the correct fittings as well as the correct number. Assembling a cooling loop with the incorrect fittings to hand or not enough of them can quickly turn into a frustrating experience - as well as holding up your build. This is an adapter in black used for extending connections within water-cooling loops. The adapter is a coupling that connects two hard tubes with outer diameters of 16 mm at a 45 degree angle. The sleeve nuts are made of aluminium and utilise two rubber rings to ensure a watertight seal.Specification:Material: Aluminium, BrassColour: BlackAngle: 45 DegreesFittings: 2x 16 mm
