Description
The Conbraco Industries 24-353-00 is a heavy-duty rough bronze liquid level gauge engineered for demanding hydronic and steam system applications. Featuring a 3/4″ OD x 16″ length high-pressure glass sight tube and 3/4″ NPT male connections, this gauge delivers reliable, at-a-glance fluid level monitoring in boilers, tanks, and related equipment.
Key Features
- 3/4″ NPT male connections for straightforward installation into standard pipe fittings
- 3/4″ OD x 16″ length high-pressure glass for a wide, clear viewing range
- Rough bronze body construction for superior corrosion resistance and long service life
- Automatic ball checks that instantly shut off flow if the glass is broken, enhancing system safety
- PTFE with Hypalon glass seal for a leak-free, chemically resistant glass-to-body interface
- Braided PTFE with Aramid stem packing for durable, high-integrity valve stem sealing
- Aluminum type wheel handle for easy manual operation

The integrated automatic ball check valves are a critical safety feature — in the event of glass breakage, the ball checks automatically seal the ports to prevent uncontrolled fluid discharge. The combination of PTFE/Hypalon glass seals and braided PTFE/Aramid stem packing ensures long-term leak-free performance even under elevated temperatures and pressures typical of boiler and hydronic applications.
