Conbraco 98-58I-30 Liquid Level Gage Glass 280 Psi

Product Description

The CONBRACO 98-58I-30 is a high pressure liquid level gage glass designed for direct visual monitoring of fluid levels in pressurized vessels and boiler systems. Rated for a working pressure of 280 psi, this gage glass is built for demanding industrial and commercial applications where accurate, reliable level indication is critical. The 30mm size designation makes it compatible with standard gage glass fittings in that bore range. Licensed plumbers, stationary engineers, and HVAC-R technicians typically install and service this type of sight glass on boilers, pressure vessels, and process piping assemblies.

This gage glass is suited for high pressure boiler rooms, industrial process systems, and commercial hydronic heating installations where fluid levels must be monitored under significant system pressure. It is commonly specified for replacement or new installation in pressurized vessel applications that require the 30mm gage glass size. Systems operating at or below 280 psi are within the rated working pressure envelope of this component.

Key Features

• Rated working pressure of 280 psi for high pressure service
• 30mm gage glass size for compatibility with standard high pressure fittings
• High pressure designation suitable for commercial and industrial boiler and vessel applications
• Single-piece packaging for individual replacement or service use

Compatibility

Designed as an OEM-style replacement gage glass for high pressure liquid level gauge assemblies requiring a 30mm bore size rated to 280 psi working pressure.

Installation Notes

Gage glass installation and replacement on pressurized vessels and boilers must be performed by a licensed plumber or qualified stationary engineer in accordance with applicable local codes and ASME boiler and pressure vessel standards. Isolate and fully depressurize the vessel and allow it to cool before removing or installing gage glass components. Inspect packing, gaskets, and gauge cocks for wear or damage during any gage glass service. Do not exceed the rated working pressure of 280 psi in service.
