General Engineering Menu ORings Suppliers Molded ORings Services ORings Design Guidelines, Specifications, Materials An Oring , also known as a packing , is a flexible gasket in the shape of a loop; The biggest weakness of radial Oring seals is that the clearance between components creates a path for the Oring to extrude due to the pressure acting on it Components called backup rings can help alleviate this Backup rings are designed to spring out of the gland and block the extrusion gap Where an Oring alone could withstand perhaps only 00 psi, a backup ringAn Oring, also known as a packing or a toric joint, is a mechanical gasket in the shape of a torus;

The oring seal design process begins with understanding the gland type in which the seal will be seated To ensure the oring fits properly it is recommended that the oring is stretched 1 to 5% circumferential, with ideal stretch at 2% Further considerations listed below include;The appropriate seal type for the individual pumping requirements is chosen from a wide variety of different shaft seals The design is based on one of the two following principles sealing by means of a narrow radial gap (parallel to the shaft axis) or a narrow axial gap (at a right angle to the shaft axis) For both sealing principles, the gaps may either employ a contact or noncontactMechanical shaft seal Oring, stationary Oring, rotating Spring Torque transmission element Introduction 3 Operating principle This section describes how the lubricating film is generated in the sealing gap in a liquidlubricated mechanical bellows shaft seal The design differs slightly from the Oring seal shown in fig 19 In its simplest form, the mechanical shaft seal consists of

For a highpressure seal to work to optimal levels, oring design and manufacture again depends on choosing specific materials for better performance under specific conditions Orings function on the principle that even pressure placed on the (more or less incompressible) oring material creates predictable deformation patterns around the perimeter of the gasket in its groove ThisThis Oring seal design section will give you step by step instructions on how to design a seal or rubber part for your application Consider this a rubber guide or Oring guide in helping you find the exact rubber material and size you need Some parts of this online rubber or Oring design guide can be downloaded in PDF but everything can just be printed directly from our website for yourDesigning the parts of an application where orings will be applied is broadly termed "oring groove design" In order to seal properly, the oring has to deform in the application by being compressed and stretched in any number of ways The design of the groove where the oring sits plays a major role in how the oring performs its sealing role Extrusion Limits;
