Glass-Trac Liquid Level Gauges and Valves
Transparent Gages
Glass-Trac Transparent Gages use clear, see- through glass on both sides so that both the color and the interface of liquids can be viewed. Electric lighted gage illuminators are available for use on Transparent Gages and provide easy viewing of liquid levels in dimly lighted areas. Transparent Gages are made in three pressure series (maximum 3000 psig @ 100ºF) and are tapped for ½” or ¾” NPT connections. The standard Glass- Trac level gages are designed for -20ºF service.
On Glass-Trac Transparent Close Hook-up Gages with ½” NPT connections, the center-to- center dimension is the same as the overall length on standard gages. On Close Hook-up Gages with ¾” NPT connections the center-to-center dimensions is the same as the overall length on standard gages plus ⅜”.

Transparent Gage Materials / Pressure Ratings |
||
| BODY (LIQUID CHAMBER) |
Accurately machined from square tubes to provide perfect seating for gage glasses. Glass is recessed for protection. Body materials include 316 stainless steel and carbon steel. |
 |
| COVER | Glass-Trac gage covers are made of carbon steel or 316 stainless steel in all their sizes and pressure ratings for higher strength and dependable service. All covers are machined to provide recessed seating protection for the glass. |
|
| GLASS | All standard Glass-Trac Transparent Gages use tempered borosilicate glass in nine standard lengths. Each transparent glass is crystal clear and has the highest strength possible. |
