Bitspower Premium G1/4" True Brass Stop Fitting 4-pack valve

Premium G1/4" True Brass Stop Fittings

This four-pack of Bitspower stop fittings provides G1/4" threaded closures for custom liquid-cooling loops. Each valve is machined from high-quality brass with a durable nickel finish in a true brass colour. The hidden O-ring design ensures a clean seal without exposed rubber. They suit builders who need reliable shut-off points for maintenance or leak testing.

Sustained sealing under system pressure

The fittings maintain a secure seal during continuous pump operation and repeated thermal cycles. Brass construction resists deformation so the G1/4" threads stay tight over long periods. The 5 mm thread engagement depth gives consistent contact with standard water-block ports and radiators. They are not intended for high-vibration mobile applications where thread-locking compounds would be required.

Thermals noise and power in normal use

As passive brass components the valves add no active heat, noise or electrical draw to the loop. The nickel plating resists corrosion so coolant chemistry remains stable without contributing particulates. Their mass is negligible compared with radiators or reservoirs so they do not affect warm-up times. No external power or control signal is needed for operation.
