Kaufman Glass Company offers the finest gauge glasses in the industry, Macbeth, Klinger and Maxos brands. These glasses are designed for maximum performance where equipment life and efficiency depend on accurate liquid control at all times. Our gauge glasses conform to all United States government and military standards, in fact they have set the industry standard with the tightest specs for flatness and quality.

Our gauge glass can be supplied plain, with standard gaskets and mica shields or custom fabricated to your exact specifications. They are available in three types:

• Type A Plain is designed for moderate pressure steam boilers and for liquid level indicators.
• Type A High Pressure is designed to withstand pressures up to 5000 psi
• Type B Reflex is designed for extra ease in locating liquid levels. This gauge glass has vertical prims extending the full viewing length of the glass. The prism side faces the liquid. The sections of the prisms covered with liquid do not reflect light.

The sections of the prisms not covered with liquid reflect light brilliantly. Thus the liquid level stands out extra clearly from a great distance away for easy viewing.

All glasses are imprinted with glass type and date of manufacture. High pressure glasses are labeled H.P. All glasses are packaged in protective plastic sleeves to guard against scratches and packed in color coded boxes. Use and care information is available with all glasses for ready reference.

GASKET AND SHIELDS FOR FLAT GAUGE GLASS

Non-Asbestos Gaskets are general purpose gaskets used for service in hot water, mild acids, alkaline and inert gasses. They are used up to a maximum temperature of 600°F and maximum pressures up to 1200 PSI in non-steam applications.

- Grafoil GH-L Gaskets are flexible graphite gaskets which are widely used in refineries, petrochemical and power plants in high temperature and high pressure applications. Dimensionally stable, grafoil gaskets offer excellent sealing capabilities under extreme conditions for longer equipment life and less maintenance.

-Mica Shields provide the best possible protection to flat transparent, sight glasses in water and liquid gauges and columns because they retain their basic strength in high pressure, high temperature applications. They provide perfect visibility for monitoring the nature and degree of combustion in blast furnaces of steam boilers.

Mica Shields also protect the inner surfaces of transparent glasses against the effects of erosion from chemical abrasion and from the corrosive chemical effects of alkaline solutions, boiler waters, caustics, hydrofluoric acids, hot concentrated phosphoric acids, sodium and potassium hydroxides and other contaminated viscous or corrosive media. They provide an excellent sealing strength against acid, steam, water, air and oil at extreme pressures and temperatures and completely eliminates the risk of cracks, breakage, jerks, shocks and combustion effects. As a rule of thumb, Mica Shields are a must where saturated steam pressure exceed 350 psi (up to 5689 psi) and working temperatures exceed 196°C (up to 600°C).

- Kel-F Shields were originally developed to withstand extreme temperature to 400°F and to resist corrosive chemical attack. They are impervious to moisture, have superior mechanical properties and reasonable visual clarity. Kel-F Shields are widely used in the chemical industry to protect the glass surface in visual liquid level gauges from corrosive attack.
