Series GL level indicators utilize a double-wall construction to indicate the level of highly corrosive or ultra-pure liquids compatible with Pyrex glass. They cannot be used with hydrofluoric acid or sodium hydroxide as they will etch the Pyrex cylinder wall. They are available with either PVC, natural polypropylene or PTFE ends in nominal lengths of 1, 2, 3, and 4 feet. FKM seals are standard. Pipe sizes are 1/2" and 3/4" NPT. BSP (British Standard Pipe) threads are also offered. Consult page 4 for pressure and temperature specifications.
