PrimoChill Female to Female G 1/4 Drain Valve SX Candy Purple diy cooling

Drain Valve for Custom Loops

The PrimoChill Female to Female G 1/4 Drain Valve adds a dedicated drain or fill point to a custom water-cooling loop. Its G 1/4 threads accept standard fittings on both ends. The powder-coated nickel-plated brass body resists corrosion while the Candy Purple finish matches themed builds. It suits builders who want a clean, serviceable loop without cutting tubing.

G 1/4 Thread Compatibility

The valve uses female G 1/4 threads on both ports, so it connects directly to any matching male fitting. No adapters are required if the rest of the loop uses the same thread standard. Over-tightening can strip the threads, so hand-tighten only. Builders using non-G 1/4 thread standards cannot use this valve without separate adapters.

Single-Port Drain or Fill Use

One valve provides a single controlled opening for draining or filling the loop. It handles the full flow of a typical custom loop when opened. Systems that need simultaneous drain and fill ports, or multiple drain points, will require additional valves. The ball-valve mechanism gives a positive open or closed position with a quarter turn.
