Bitspower G1/4" Flow Indicator Clear Black Blade Matte Black

Flow Indicator for Water Cooling

The Bitspower G1/4" flow indicator lets you visually confirm coolant movement inside a custom loop. Its clear main body shows the black blade spinning when fluid circulates, giving immediate feedback that the pump is working. The fitting uses a standard G1/4" thread so it integrates with most hard-tube or soft-tube builds. It is aimed at enthusiasts assembling or troubleshooting liquid-cooled PCs.

Hidden O-ring and Brass Construction

The hidden O-ring design seats the seal inside the fitting rather than against the port face, reducing the chance of visible leaks during installation. Hi-quality brass construction resists corrosion from common coolants and additives. The matte black finish matches dark-themed builds without adding bulky RGB or lighting hardware. No software or controllers are bundled; the indicator is purely mechanical.

Visual Flow Confirmation Only

The device comfortably handles normal loop flow rates by spinning a lightweight blade, letting you verify that coolant reaches every block. It provides no temperature, pressure or flow-rate readings, so builders who need precise metrics must add separate sensors. The clear acrylic window can scratch if cleaned with abrasive tools, and the G1/4" thread limits use to components sharing that pitch.
