Conbraco 24-353-00 Gauge

The Conbraco 24-353-00 Gauge is a professional-grade liquid level water gauge designed for demanding boiler and pressure vessel applications. Built with a heavy-pattern rough bronze body, this 3/4" NPT set provides industrial-strength performance for commercial HVACR and steam systems. It features automatic ball checks in both the upper and lower arms, which conform to ASME power boiler code requirements by instantly seating to prevent fluid loss in the event of glass breakage. The assembly is equipped with high pressure glass measuring 16 inches in length, secured by high-performance PTFE with Hypalon seals and braided PTFE with Aramid stem packing for maximum leak resistance. Operating pressure ratings are substantial, supporting up to 250 PSI at 400°F or 500 PSI at 100°F. For manual operation, the aluminum type wheel handle provides precise control and long-term durability in high-heat environments. This liquid level gauge is the standard for contractors seeking reliable visual monitoring and safety compliance.

• Automatic Safety: Integrated ball checks provide immediate shut-off if the sight glass fails, meeting strict ASME safety standards.
• High-Temperature Durability: Premium PTFE/Aramid packing and Hypalon seals maintain integrity under extreme thermal cycling up to 400°F.
• Industrial Build: Heavy-pattern bronze construction resists corrosion and mechanical stress better than light-duty alternatives.
• Enhanced Visibility: The 3/4" OD high pressure glass offers a clear, wide viewing area for accurate fluid level verification.
• Manual Control: Features a rugged aluminum handwheel and a 5/16" ball valve drain for easy system blow-downs.

Is the gauge glass and protection rod set included with the 24-353-00?
Yes, this specific model number includes the 16" high-pressure glass. However, guard rods are often sold separately or as part of a complete kit; verify if your application requires the four-rod guard bracket for additional protection.

Can this gauge be used on ASME power boilers?
Yes. Because it features automatic ball checks that seat vertically/properly, it conforms to the ASME Power Boiler Code for automatic water gauges, making it suitable for high-pressure steam applications.

What is the difference between standard and high-pressure glass for this unit?
Standard glass has lower pressure thresholds. The 24-353-00 is specifically outfitted with high pressure glass to support the 250 PSI at 400°F rating, ensuring it handles the stresses of industrial steam service.
