Tubular Level Gauges are designed to view liquid levels using clear or red line Borosilicate (Pyrex) tubing to view liquid levels. All valves use a stuffing box configuration to seal the glass tube, and have a ball check shutoff to prevent loss of vessel contents in case of glass failure. Operating pressure and temperatures are subject to the limitations of the tubular gauge glass and washer composition. These valve bodies are rated for 500 PSIG at 450F. The actual pressure limitations are of the gage glass. Use with oils or petrochemical liquids, as well as water and steam. Please check your process fluid's compatibility with Buna seal materials.

The following pressure values are for industry standard high pressure gage glass use.
