Alphacool connectors are breaking new ground in form, design, color, and variety. The newest innovation is an outstanding inner diameter that really earns the descriptor "high flow"! The first three colors, chrome, deep black, and shiny copper, offer a great variety to suit many tastes. The fully coordinated product series gives every system a chance to shine, and the customization options are endless when paired with Alphacool tubing! A new chromatization technique binds the coloring tightly to the brass surface. This improves the longevity of the intense color and prevents any chipping of the chrome layer. Blue Alphacool lettering on some of the connectors also highlights the uniqueness of these parts. The function of these connectors is: This bulkhead connector can be used to lead a hose through a case with the help of two connectors, for example. The connector, together with its counter nut, is screwed to the case and its 1/4" inner thread can then be connected to a standard hose connector. Model: 17424
