Conbraco 26-705-01 Gauge Cock

The Conbraco 26-705-01 is a professional-grade 1/2 inch NPT gauge cock designed for precision pressure monitoring in commercial boiler and steam systems. Engineered with a durable satin brass body, this compression-style cock features a high-performance TFE seat and a composite wheel for smooth manual throttling and positive shut-off. Rated for demanding environments, it handles up to 250 PSI at 400°F, making it a reliable choice for high-temperature steam applications and water line isolation. The male NPT connection ensures a secure, leak-free fit with standard piping configurations. For contractors managing boiler site glass assemblies or pressure gauge isolation, this valve provides the necessary chemical resistance and thermal stability required for long-term service life. Its robust construction minimizes the risk of seat galling, ensuring accurate readings and safe maintenance procedures during routine HVAC system inspections and industrial fluid control tasks.

Key Benefits for Technicians

• High-Temperature Rating: The TFE seat maintains integrity up to 400°F, ideal for saturated steam services.
• Durable Composite Wheel: Provides excellent thermal insulation for the operator and resists impact damage in mechanical rooms.
• Satin Brass Finish: Offers superior corrosion resistance and professional aesthetics for commercial plumbing installations.
• NPT Compatibility: Standard 1/2" male threads allow for easy integration with industrial pressure gauges and siphons.
• Reliable Shut-off: Precision-machined internal components prevent bypass, ensuring accurate zeroing of gauges during calibration.
