G 1/4in Drain Ball Valve

This brass valve provides a sealable G 1/4in female thread at both ends for custom water-cooling loops. It functions as a fill port on the top of an enclosure or a drain at the bottom. The compact body measures 36.12mm long, 35.61mm high and 23.20mm wide. Diamond-knurled surfaces aid grip during hand installation.

Interface Limits

The valve accepts only standard G 1/4in fittings; other thread sizes will not seal correctly. It is rated for typical liquid-cooling pressures but not for high-pressure industrial lines. The rotary handle allows smooth shut-off, yet the mechanism is not designed for frequent flow modulation. Brass construction resists corrosion from common coolants but may react with aggressive chemical additives.

Capacity and Headroom

The short internal path adds minimal restriction to a single-loop system. It handles standard fill and drain cycles without leakage when fittings are properly seated. Loops with multiple parallel blocks or very high flow rates may see a slight pressure drop across the valve. Builders needing a second drain point or a larger bore for high-volume reservoirs should choose a different component.

商品問答

Should I choose this valve as a top fill-port or a bottom drain?

It works in either position; the dual female G 1/4 in threads let you install standard fittings at both ends so the same valve can serve as a fill port on top or a drain at the bottom.

What does the 35.61 mm height mean once the valve is in my loop?

The valve body measures 35.61 mm tall, 36.12 mm long and 23.20 mm wide, so you can check clearance against adjacent blocks, radiators or panels before mounting.

What does the G 1/4 in thread standard cap in practice?

Both ends use G 1/4 in female threads, the de-facto standard for PC water-cooling fittings, so any compatible male G 1/4 in fitting — rigid tube, soft tube or adapter — will seal directly without extra converters.
