The O-Ring is one of the most basic and functional seals ever made and is the backbone to all the hydraulic and sealing applications in the world. An O-Ring is a solid-rubber seal shaped like a dough nut or torus.
When compressed between mating surfaces, an O-Ring blocks the passage of liquids or gases. O-Rings are available in a wide range of standard and non-standard sizes that are suitable for nearly all sealing applications.
Two dimensions describe the size of an O-ring: its inside diameter ID and its cross-sectional diameter CS. To search AS sizes just type AS to bring up all the compounds that size.
To search metric O-Rings just search 2. Live chat for O-Ring Sales and service. Our basic stock compound list includes over 30 o-ring compounds making us one of the most diverse O-Ring Suppplier in the Global O-Ring market.

Manufacturers of custom rubber and silicone O-rings to your specification. The majority of these are in Nitrile However, if you require an O-Ring which is not Nitrile we can manufacture to ISO sizes but in most of the rubber materials as stated on our materials page. Please note that each rubber material shrinks at a different rate and so the tooling used to manufacture an ISO Nitrile O-Ring will not be suitable for manufacturing an O-Ring in a different material.
As a result we have customers who purchase standard size O-Rings but have custom sized O-Ring tools to allow for material compensation. We offer a fast service and can take a project from concept through to final production.

US Division: www. O-Rings and Seals. Custom O-Ring Manufacturers. Custom O Rings. Toroidal Sealing Rings. O Ring Manufacturers.A full range of non-standard o-ring sizes can be custom-made with compression molding and continuous molding. Compression molded o-rings are produced for static and dynamic applications. Compression molding is preferred when high volumes of small and non-standard sizes are needed.
Continuously molded o-rings are an excellent sealing option for large, non-standard size dynamic applications. Our continuous molding process does not require tooling and can handle virtually any ID size. It is also the best option for smaller amounts of dynamic o-rings where the volumes do not warrant having a tool cut.
Continuously molded o-rings can be used for both dynamic and static applications, as well as high-pressure and vacuum environments. Continuously molded o-rings can be produced in numerous combinations of material, durometer, ID, and cross-section. The performance of continuous molding is similar to that of compression molding, with both being made for static and dynamic applications.
For modest volumes of large-diameter o-rings, continuous molding is optimal as there is no tooling cost. Compression molding requires tooling but can be ideal when producing a large volume of o-rings. Vulcanized o-rings can be produced within hours and do not require tooling, and are best suited for static conditions. To place an order or request more information on custom molded o-rings which molding you require for your application, give us a call at or submit the Product Inquiry form.
