Conbraco 98-34P-12 Liquid Level Gage Glass 275 Psi

Product Description

The CONBRACO 98-34P-12 is a red line grade liquid level gage glass designed for visual fluid level monitoring in industrial and commercial plumbing and process systems. It provides a direct sight line to the liquid level inside a vessel, tank, or boiler, allowing technicians to verify operating levels without opening the system. The 98-34P-12 carries a 275 psi working pressure rating, making it suitable for moderate- to high-pressure applications. Red line gage glass is formulated to handle hot water and steam service conditions. Licensed plumbers, pipefitters, and stationary engineers are the typical installers of this component.

This gage glass is used in residential and commercial boiler installations, process vessels, and storage tanks where a reliable visual level indicator is required. It fits into standard gage glass fittings and valve assemblies designed for sight-glass applications. The red line designation indicates compatibility with hot water and low-pressure steam service, common in hydronic heating systems and industrial process lines. Installers typically source this as a direct replacement for worn, clouded, or cracked gage glass in existing assemblies.

Key Features

• 275 psi working pressure rating for moderate- to high-pressure service
• Red line grade construction suited for hot water and steam applications
• Direct visual indication of fluid level without system intrusion
• Designed as a replacement component for standard gage glass valve assemblies
• Single-piece packaging for straightforward field replacement

Compatibility

Designed as an OEM-style replacement gage glass for standard liquid level gage valve assemblies rated for hot water and steam service up to 275 psi.

Installation Notes

Gage glass replacement is typically performed by a licensed plumber or pipefitter. Shut off all supply and return isolation valves and fully depressurize and cool the system before removing the existing glass. Follow ASME and local mechanical code requirements for pressure vessel sight glass assemblies. Do not overtighten packing nuts, as excess compression can fracture the glass.
