Product Description

Glass-Trac Transparent Gauges use clear, see- through glass on both sides so that both the color and the interface of liquids can be viewed. Electric lighted gauge illuminators are available for use on Transparent Gauges and provide easy viewing of liquid levels in dimly lighted areas. Transparent Gauges are made in three pressure series (maximum 3000 psig @ 100ºF) and are tapped for ½” or ¾” NPT connections. The standard Glass- Trac level gauges are designed for -20ºF service.

On Glass-Trac Transparent Close Hook-up Gauges with ½” NPT connections, the center-to-center dimensions is the same as the overall length on standard gauges.

On Close Hook-up Gauges with ¾” NPT connections, the center-to-center dimensions is the same as the overall length on standard gauges plus ⅜”.
