Conbraco Industries 20-151-00 Rough Bronze Water Gauge
The Conbraco Industries 20-151-00 is a heavy-duty rough bronze water gauge engineered for reliable performance in demanding hydronic and steam system applications. Featuring 1/2″ NPT male connections and a 5/8″ OD x 12″ length standard glass, this gauge delivers clear, accurate water level visibility in boilers and pressure vessels. Built with automatic ball checks, the gauge self-seals in the event of glass breakage, protecting personnel and preventing system fluid loss. The EPDM glass seal provides excellent resistance to heat and steam, while Teflon stem packing ensures a leak-free, long-lasting seal at the valve stems. The composite plastic type wheel handle allows for easy manual operation even in tight spaces.
