Conbraco 20-254-00 Bronze Liquid Level Gage Glass 400 Psi

Product Description

The CONBRACO 20-254-00 is a bronze liquid level gage glass fitting designed to support tubular sight glass assemblies in pressurized fluid systems. It accepts a 16-inch tubular gage glass and is rated for a maximum liquid pressure of 400 psi and a maximum operating temperature of 400 degrees F. The fitting uses a 3/4-inch threaded connection and an EPDM seal for reliable, leak-resistant performance. Licensed plumbers and industrial maintenance technicians install this type of fitting on boilers, pressure vessels, tanks, and process piping where visual liquid level monitoring is required.

The 20-254-00 is suited for residential and light commercial boiler applications as well as industrial process systems that require a direct-reading liquid level indicator. It is appropriate for installations where the working fluid is compatible with bronze wetted parts and EPDM seals. The 3/4-inch threaded connection is a common configuration on boiler columns, tank fittings, and gauge cocks used across the hydronic and process industries.

Key Features

• Maximum liquid pressure rating of 400 psi for demanding pressurized system applications
• Maximum operating temperature of 400 degrees F suitable for steam and high-temperature hydronic service
• EPDM seal material provides resistance to hot water and steam service conditions
• 3/4-inch threaded connection for straightforward installation on standard fittings and gauge cocks
• Designed for 16-inch tubular gage glass, a widely used sight glass size
• Meets ASSE, ASTM B16, ASTM B584, and CSA standards

Compatibility

Designed for use with 16-inch tubular gage glass in standard bronze liquid level gage glass assemblies on pressurized tanks, boilers, and process vessels with 3/4-inch threaded connections.

Installation Notes

Installation should be performed by a licensed plumber or qualified industrial technician. Depressurize and drain the system completely before removing or installing any gage glass fitting. Inspect the EPDM seal and glass tube for damage prior to assembly, and do not overtighten the packing nuts, as excess force can crack the glass. Follow applicable plumbing codes and pressure vessel standards for your jurisdiction when installing sight glass assemblies on boilers or pressure vessels.
