Metric Urethane O-Rings – Polyurethane Metric O-Rings

Metric urethane o-rings are cast using high-quality urethane prepolymers specially formulated for a low compression set and great sealing ability against gas and oils. Metric urethane o-rings are available in any size or profile and are most commonly produced using compression molding. This will yield parts to print with no secondary process saving you money!

Urethane is intended for high-performance applications where typical rubber o rings will fail. Metric urethane o-rings are available in all durometers and sizes. A variety of additives can be added to enhance wear properties or abrasion resistance. A metal detectable additive can also be added for X-ray equipment required for FDA applications. We also cast FDA Dry food approved urethane o-rings. Metric urethane o-rings can be molded with any added thru hole for a hinge or any other configurations as well. We can also make custom urethane o-rings without the traditional circular style if your custom application requires a different shape for the metric urethane o-rings. Urethane is a great choice for high-pressure sealing devices due to the ability to tailor our chemicals in our state of the art urethane manufacturing facility. We can provide any hardness needed for your application or sealing needs. Custom urethane o-ring sizes are no problem for us here at Plan Tech!


For over 30 years we have focused on using speed and precision to manufacture the highest quality industrial Custom urethane metric o-rings to our customers. A particular strength is the breadth of our in-house capabilities such as grinding urethane parts which, when combined with our extensive experience, enables us to deliver tight tolerance urethane metric o-rings while maintaining the quality control and cost effectiveness our customers require. The tests are performed according to an established set of standards provided by an accredited testing organization such as the Society for Testing and Materials (ASTM) who define the procedures in detail.
