Conbraco 26-105-28 Gauge

The Conbraco 26-105-28 is a professional-grade 1/2" Male NPT compression gauge cock designed for reliability in low-pressure steam and liquid monitoring systems. Engineered with a polished brass body, this ball-valve type 1/2-inch gauge cock provides a secure, leak-free connection for industrial boiler sight glasses and instrumentation manifolds. Rated for a maximum working pressure of 125 PSI, it features a durable composite plastic wheel for smooth manual operation, allowing technicians to isolate pressure gauges for calibration or replacement without depressurizing the entire system. The male NPT threaded connection ensures compatibility with standard piping configurations, making it a staple for HVACR contractors maintaining commercial heating plants. Its rugged construction resists corrosion and mechanical fatigue, providing a stable interface for brass water gauges and steam boiler pressure sensors in demanding mechanical room environments.

Common Questions

What is the maximum temperature rating for this gauge cock?
This 1/2" NPT brass valve is typically rated for saturated steam temperatures consistent with 125 PSI service, though seals should be verified for specific high-temp chemical applications.

Can this be used for potable water systems?
The Conbraco 26-105 series is primarily designed for HVACR and boiler applications; always check local codes regarding lead-free requirements for drinking water installations.

Is the wheel handle replaceable if damaged?
Yes, the composite wheel is a standard Conbraco component, allowing for easy field service without replacing the entire pressure gauge valve.
