Conbraco 24-301-00 Gauge

The Conbraco 24-301-00 is an industrial-grade rough bronze liquid level gauge designed for demanding HVACR and boiler applications. Engineered with a heavy-pattern bronze valve body, this set features 1/2" NPT male pipe connections and comes standard with 5/8" OD x 12" high-pressure glass. The assembly utilizes high-performance PTFE with Hypalon glass seals and braided PTFE with Aramid stem packing to ensure leak-free operation under thermal cycling. The inclusion of an aluminum handwheel provides a durable, heat-resistant grip for manual isolation. This direct-reading gauge is rated for 250 PSI at 400°F and 500 PSI at 100°F, making it a reliable solution for monitoring liquid levels in steam boilers and pressure vessels across the mechanical room.

• Enhanced Durability: The rough bronze construction resists corrosion in high-temperature steam environments.
• High-Pressure Ready: Ships with 12-inch high-pressure glass capable of handling 500 PSI at ambient temperatures.
• Advanced Sealing: Features braided PTFE with Aramid to prevent stem leaks and withstand aggressive chemical media.
• Standard Compatibility: The 1/2 inch MNPT connections fit standard boiler tappings for straightforward replacement.

Is the Conbraco 24-301-00 considered an automatic water gauge?
This specific model is a standard non-automatic gauge. For applications requiring ASME automatic ball checks to prevent fluid loss during glass breakage, refer to the 24-350 series.

What is the maximum service temperature for the 24-301-00?
The gauge is rated for operation up to 400°F at 250 PSI. Always verify that your specific system pressure does not exceed the glass rating at your operating temperature.

How do I prevent leaks at the glass packing nuts?
Ensure the PTFE glass seals are properly seated and avoid over-tightening. Hand-tighten the nuts and then apply a 1/4 to 1/2 turn with a wrench to achieve a secure seal without stressing the glass.
