Roto Seal Couplings are high pressure pneumatic device which acts as a seal between the stationary components such as pipe and rotating component like cylinder/drum to allow the fluid into or out of the rotating parts. These are mainly used for the transportation of fluid such as steam, water, thermal oil, hydraulic fluid, and coolants. Roto Seal Couplings are widely used in many industries like agriculture, automotive, mining, textile, rubber, plastic oil and gas. The material used in the manufacturing of these seals is steel with galvanized surface treatment which give high strength and make them corossion resistant. These couplings are available in various different size as per the system requirement where they are going to be used.
