Technical data
Mica Sealing Kit for Level Gauge Glass Overview
The Mica Sealing Kit is a complete sealing and protection solution used in transparent level gauges and reflex level gauges operating under severe service conditions.
In steam applications, hot condensate and dissolved chemicals can gradually attack the surface of gauge glass, reducing transparency and shortening service life. The mica shield acts as a protective barrier between the process medium and the glass surface, significantly improving operational reliability.
Combined with graphite gaskets, alloy support spacers, and graphite protection strips, the sealing kit provides excellent resistance to temperature, pressure, and chemical exposure while ensuring secure sealing performance.
All components are precision manufactured to match standard DIN 7081 gauge glass dimensions or customer-specific requirements.

FAQ
A: A mica sealing kit is used to protect gauge glass in level gauge assemblies operating under high temperature, steam, and chemically aggressive conditions.
A:Mica provides excellent transparency, heat resistance, and chemical stability. It acts as a protective barrier that prevents direct contact between process media and the gauge glass surface.
A:Mica shields are commonly recommended for steam service, boiler applications, alkaline solutions, and other environments that may damage exposed gauge glass.
A: A standard kit typically includes mica shields, graphite gaskets, alloy spacers, and graphite protection strips.
A:Yes. We manufacture custom dimensions to match DIN 7081 gauge glasses and customer-specific designs.
