The lined rubber sight glass is used to observe the flow rate and color changes of unit fluids in pipelines or equipment, and directly monitor the chemical process flow. The mirror body is made of precision cast carbon steel and lined with fluoroplastic (F46). The lenses are made of high-quality tempered glass, which has excellent corrosion resistance and mechanical strength, as well as beautiful appearance, high strength, and durability.

Rubber lined sight glasses are widely used in industries such as petroleum, chemical, pesticide, dyeing, acid and alkali production, and are currently the ideal choice for anti-corrosion equipment.

Rubber lined sight glasses can be used in pipelines of industrial production facilities such as petroleum, chemical, pharmaceutical, and food industries to observe the flow of liquids, gases, vapors, lubricants, and other media in the pipelines at any time. They play a role in monitoring production and avoiding accidents during the production process. They are an indispensable accessory on pipeline installations. Mainly used for observing liquid flow in liquid pipelines such as drainage or reflux before receiving tanks, cooling water, etc.
