No cheap plastic or fragile glass here. Eyeball's level indicators use only the highest quality materials; made of solid brass, steel and stainless steel, which won't rust into the tank and a special polymer bulb design that is impervious to antifreeze, hydraulic oils, gasoline, oils and many other liquids. This combination of materials creates a superior performing sight glass with reliable viewing. Not only is this a high quality sight glass with unique features, it is competitively priced to deliver maximum value.
