Seals - Global O-Ring and Seal

Industrial seals are used to prevent air and fluid leaks, maintain pressure and deflect contamination between two components by creating a tight enclosure. The type of seal used depends on the surface of the components, which can be either static (not moving relative to each other) or dynamic (in motion). Static seals, such as adhesives and gaskets, are used in stationary components, while dynamic seals are used in moving elements like cylinders, motors, and pumps. There are many options for seal materials, including rubber, polytetrafluoroethylene (PTFE), fluorosilicone (FVMQ), and polyurethane (AU, EU). The nitrile rubber O-ring, also known as Buna-N, is a common and primary seal for hydraulic and sealing applications and can withstand high pressure. As health and safety regulations become stricter, there is a greater need for reliable seal performance in pressurized rotating equipment to prevent contamination. Centro offers expertise in seal technology, inventory management, and repairs to help customers solve sealing issues and improve pump efficiency, process reliability, and product quality.
