GAUGE GLASS
Superior Products
The Superior Products Gauge Glass is the visual reading element for level gauge assemblies on tanks and vessels. It is offered in red line and transparent styles to suit the reading method and lighting, with transparent acrylic tubes also available.
Wall thickness options cover standard, high pressure, and heavy wall service, so the glass can be matched to the pressure. The glass pairs with Superior gauge cocks and guards for a complete, safety-focused level indication package.
Available in 5/8" and 3/4" OD, the gauge glass stocks in lengths from 12" to 72" with custom lengths available. Made in the USA.
Typical Applications:
Tank and vessel level gauging, high-pressure gauge assemblies, gauge glass replacement, separator and treater level indication, and direct visual level reading.

PERFORMANCE ADVANTAGES
Why the Superior Gauge Glass Performs Where It Counts
READABLE IN ANY CONDITION
Red line and transparent styles let the glass be matched to the reading method and lighting, with acrylic tubes as an alternative. Operators get a clear level reading whatever the installation.
MATCHED TO SERVICE PRESSURE
Standard, high pressure, and heavy wall options let the glass be specified to the working pressure rather than over- or under-built. That delivers the right strength for the application.
SIZED FOR THE ASSEMBLY
Stocked 5/8" and 3/4" OD in lengths from 12" to 72", with custom lengths available, the glass fits standard gauge valve assemblies and non-standard vessels alike. Replacement and new builds are both covered.
PART OF A COMPLETE PACKAGE
Paired with Superior gauge cocks and guards, the glass forms a matched level-indication assembly built around operator safety. One source covers the full package.
