Diaphragms are Flexible Rubber walls separating chambers which acts as a sealing by preventing flow of materials or fluids between the two separated chambers. Widely used in Pumps, valves and actuators to regulate flow of Gases and transfer of Fluids.

An ‘O’ Ring is a elastomeric component in a shape of Torus. A loop of elastomer with a round cross-section. General and common application is for Sealing requirement towards Fluids and Gas by means of compression of the ‘O’ Rings especially as they are inexpensive, Reliable, Simple to install and easy to manufacture.
