The Blue-White 70000-618 Tube Indicator Glass is a simple, reliable flow-verification accessory combining a glass-float indicator with 10 feet of flexible 3/8-inch tubing. Designed for use in chemical-feed, water-treatment, pool/spa, or industrial fluid systems, the indicator provides a clear, visual confirmation of liquid flow as fluid moves through the tubing, an internal float rises and falls, making it easy to verify that your pump is drawing or dispensing fluid.
This indicator helps detect pump failures, suction leaks, or flow interruptions at a glance without tools or gauges. It’s ideal for applications where a quick visual check is more practical than installing a full flow meter, and it integrates seamlessly with standard 3/8" tubing setups.
