Conbraco 26-308-28 Gauge C

Engineered for high-pressure hydronic and steam applications, the Conbraco 26-308-28 is a professional-grade 3/4" Male NPT Brass Compression Gauge Cock designed for reliable fluid isolation and system monitoring. Built from polished brass, this multi-port tri-cock features a soft metal seat and stuffing box assembly, ensuring a drip-tight seal and superior packing longevity even under thermal cycling. The unit is equipped with a high-visibility composite plastic wheel for manual operation in tight mechanical spaces, providing technicians with precise control for draining expansion tanks or isolating liquid level gauges.

With a robust 250 PSI pressure rating at temperatures up to 400°F, this MNPT water gauge valve is a standard-issue component for contractors maintaining commercial boilers and storage vessels. Its angle piping configuration and 0.52 lb lightweight construction allow for versatile installation in existing 3/4" NPT headers. The Conbraco 26-300 series design prioritizes field serviceability, utilizing a compression gauge cock mechanism that stands up to the rigors of saturated steam and aggressive water chemistries. Rely on this authentic Apollo Valves component for precise boiler sight glass isolation and system blowdown procedures.
