At Associated Fastening, we’ve manufactured and distributed standard and specialty fasteners for over three decades. This experience gives us the knowledge and skills needed to provide quality fastening parts and products to customers in a diverse set of industries. One of our core product offerings is O-rings. They are available in standard and custom variations.
Overview of Rubber O-Rings
O-rings are circular gaskets used to form a fluid-tight seal between two mated surfaces in a fastened assembly. They are generally extruded, molded, or machined from elastomeric materials, such as rubbers, which allows them to be compressed between the surfaces without permanent deformation. This quality enables them to maintain their sealing performance characteristics from one cycle to the next.
There are many rubber materials used in the manufacture of O-rings, each of which offers different properties that make them suitable for different sealing applications. Some of the most common include PTFE, EPDM, silicone, Viton, BUNA, and nitrile.
Industrial Applications of Rubber O-Rings
O-rings find use in liquid and gas sealing applications across a wide range of industries, including, but not limited to, the following:
- Original Equipment Manufacturing (OEM)
Standard vs. Custom Rubber O-Rings
Standard rubber O-rings, available in many materials, finishes, and sizes, serve as a cost-effective sealing component for many typical liquid and gas handling systems. However, for highly specialized or critical sealing applications, custom O-rings are generally more appropriate. These components are manufactured to the exact specifications needed for the fluid handling equipment, ensuring the formation of a leakproof seal.
