Conbraco 9858P-12 Red Line Gauge Glass 5/8" OD x 12" Length

The Conbraco 9858P-12 is a high-pressure tubular gauge glass designed for liquid level monitoring in boilers, steam systems, condensate return tanks, and reservoir applications. This 12-inch length glass tube features a 5/8-inch outside diameter and is constructed from durable borosilicate glass for superior thermal shock resistance and high-pressure performance.

Key Features:

• Red line indicator between two white stripes for enhanced visibility of colorless liquids
• 5/8" outside diameter, 12" length tubular sight glass
• Borosilicate glass construction with low thermal expansion coefficient for thermal shock resistance
• Suitable for high-pressure and high-temperature industrial environments
• Compatible with standard water gauge valve assemblies (sold separately)
• Designed for boiler water level, condensate tank, and liquid reservoir monitoring

The red line design makes water level readings quick and accurate by providing clear contrast against colorless liquids. This replacement gauge glass is commonly used in steam boiler systems, industrial tanks, and other applications requiring reliable visual liquid level indication. Conbraco gauge glasses are known for precision and durability in demanding industrial settings.
