The O'ring

An o-ring is one of the most simple, yet highly critical, precision mechanical components ever developed. When pressed between two mating surfaces, O-rings block the passage of liquids or gases. Simple, inexpensive, easy-to-install O-rings are efficient seals for a variety of applications.

Our O-rings are available as industry-sized stock materials, or can be custom made to fit your sealing application. Feel free to contact us for a quote.
