OneMonroe O-rings are the industry standard for sealing solutions, offering simplicity, durability, and efficiency across a wide range of applications. Designed to handle pressures up to 3000 PSI, these seals are easy to install and can function effectively as double-acting seals, ensuring dependable performance under demanding conditions. When working with pressures above 800 PSI, back-up rings can be incorporated to enhance stability based on specific operating conditions and gland design. While ideal for static and reciprocating applications, O-rings are not recommended for rotary uses, as they tend to rotate with the shaft and may cause leaks; for rotary functions, lip seals are a better choice.

Each OneMonroe O-ring is available in various sizes, specified by inside diameter and cross-section dimensions, ensuring that you can find the exact fit for your needs. In cases where non-standard sizes are required, we offer customized dimensions, though tooling charges may apply. Our O-rings are manufactured with different compounds and durometer hardness options to best suit the application environment, making them a versatile choice for various industries. They are widely used in biotech, food and beverage processing, medical equipment, and pharmaceuticals, meeting strict industry standards for performance and quality.

With a comprehensive range of resources, OneMonroe provides the necessary tools and guides to help you make informed choices for your O-ring needs. From our Comparison Properties Chart to our PTFE Encapsulated O-rings and O-ring Groove Design Chart, we provide everything you need to select the most suitable sealing solution for your specific application.
