One of the first types of products we ever worked with was the rubber O-ring back in the 1950s. They are simple and basic items, but that doesn’t change how important they are in a variety of applications. As their name implies, O-rings are small, donut-shaped pieces of rubber that are meant to create a seal between two components like pumps, cylinders, connectors, and valves. O-rings are available in all different sizes and thicknesses so they can be used in your specific application to stop the unwanted spread of gas and liquid where they are not meant to be. On top of sealing off different elements, O-rings can also be used for high-temperature sealing, high-pressure sealing, engines, plumbing pipes and fixtures, and even food-grade safe applications!
