MODEL EFI GY-FL
(All Bolting Stainless Steel)

They cannot be used with hydrofluoric acid or sodium hydroxide as they will etch the borosilicate cylinder wall. PVC ends are standard. PP, CPVC, PTFE and Kynar® ends also available. Fluorocarbon seals are standard. These indicators will fit1-1/2” through 8” smooth face standard companion flanges. Two flange O-ring seals are supplied, therefore, other gasketing materials are not required. The inner cylinder is borosilicate for maximum corrosion resistance and the outer cylinder is high impact acrylic, which acts as a protective shield against external impacts.
