Alphacool High Flow Bulkhead Connector - G1/4 Thread Deep Black Water Cooling Fitting

About This Product

PC water cooling enthusiasts, this Alphacool bulkhead connector is exactly what you need for clean pass-through connections in your custom loop! The G1/4 thread is standard for most water cooling components, and the deep black finish looks sleek and professional in any build. What sets this apart is the high-flow design with optimized inner diameter that minimizes restriction in your coolant flow. The chromatising process used in manufacturing ensures the color is permanently bonded to the brass body, so you don't have to worry about peeling or fading over time. I've used several of these in my latest build for passing tubing through radiator compartments and reservoir mounts - they create such a clean, professional look compared to tubing running through oversized holes. The 21mm mounting hole size is pretty standard for bulkhead fittings. The quality is typical Alphacool - precise threads that seal perfectly with minimal tightening, and the deep black color is consistent and rich. Whether you're building in a case with separate compartments, setting up external radiators, or just want that clean pass-through look, this bulkhead connector delivers both function and style. The high-flow design means you're not sacrificing performance for aesthetics. Perfect for serious water cooling builds where every component choice matters for both looks and thermal performance.
