Fluid Level Sight Glasses

The SG and SGA Series of fluid level sight glasses are utilised as oil level indicators in oil tanks, gearboxes and general machinery. The transparent component, the high density polyamide, is impervious to oil, gasoline, lubricants, and most petroleum solvents. Technical tables of chemical resistance are available on request. Avoid contact with alcohol, ethanol, methanol, and fluids with a high concentration of glycol.
