Roto Seal Coupling is a type of rotating joint which is used for allowing rotation of parts that are united with each other. It is a kind of a device which works as a seal between a stationery and a rotating instrument. This allows the flow of media smoother & easier. Roto seal couplings are designed in a way that fluids like, hydraulic fluid, coolants, thermal oil, grease oil can flow with an ease between two agents.

The coupling locks the input valve during its rotation to meet an outlet valve. Any fluid either gas or liquid will get stored in the roto seal itself due to its movement.  This fluid will release from the  coupling when it meets with the valve opening during rotation. Similarly more fluid will enter into the coupling for next process. This coupling is designed such a way that it always rotates around its axis and provides constant movement under high pressure. Design of the coupling varies as per the rpm, psi or number of valves required. It is used across industries such as pharmaceutical, chemical, paper, food, plastic, steel, oil and many more.
