Conbraco 9858P-36 High Pressure Gauge Glass Red Line 5/8" OD x 36" Length

The Conbraco 9858P-36 is a high-pressure gauge glass designed for liquid level verification in boiler and industrial applications. This red line sight glass measures 36 inches in length with a 5/8-inch outside diameter, making it suitable for medium to large water column installations.

Key Features:

• 36-inch tubular glass length for extended viewing range
• 5/8" outside diameter for standard gauge valve compatibility
• Red line indicator for enhanced liquid level visibility
• Borosilicate glass construction for durability and thermal resistance
• Compatible with Conbraco/Apollo 20-series and 21-series water gauge valve sets

This replacement gauge glass is commonly used in boiler water columns, steam systems, tanks, and other liquid level measurement applications. Installation requires proper handling—do not reuse any tubular glass or glass packings, and do not allow glass to touch any metal parts. For complete installation, this glass tube must be used with upper and lower gauge valves, appropriate gaskets/washers, and protection rods (all sold separately).

Application: Designed for use with Conbraco/Apollo standard and heavy pattern bronze water gauge assemblies for reliable liquid level monitoring in industrial and commercial settings.
