Static o-ring face seals, used for a wide variety of applications, come in many shapes and forms. Whether you need bolted flanges or removable lids, this o-ring face seal groove design guide will help you choose the right o-ring for your application. O-Ring Size Charts O-ring, x-ring and square ring size charts.

At my workplace we use lots of components that are made by professionals that have completely rectangular o-ring grooves. Most components are

Static vs Dynamic O-Ring Groove Design Considerations. Static O-ring applications — where the two components being sealed together don’t move — are the most common use for

OSCILLATING SEALS - The inner or outer member of the assembly moves in an arc relative to the other, rotating one of the members in relation to the O-Ring. Sealing can be complicated by the fact that the O-Ring can snake or bunch in the gland. The relative motion of the moving part to the fixed part tries to carry its O-Ring contact with it, distorting the rubber circumferentially.

Between :15%-25% squeeze on the O-Ring. Static seals can tolerate higher volume swell of the O- Ring than dynamic seals. B. Dynamic seal grooves are normally designed to have about 15% squeeze on the O-Ring. Less squeeze increases probability of leakage while more squeeze increases friction and probability of spiral failure.

O-RING GROOVE DESIGN. Designing the parts of an application where o-rings will be applied is broadly termed "o-ring groove design". In order to seal properly, the o-ring has to deform in the application by being compressed and stretched in any number of ways. The design of the groove where the o-ring sits plays a major role in how the o

O-Ring cross section and o-ring groove design data from ROW, Inc. manufacturers of encapsulated o-rings and industrial gaskets.

For additional information about O-ring and back-up ring materials, refer to Materials and about extrusion, refer to Gap extrusion. Housing groove width. To accommodate the additional back-up rings, the O-ring groove width L needs to be increased to L1 for one back-up ring or L2 for two back-up rings . The groove width dimensions are listed in

The three main types of standard groove designs are Industrial Static also called Radial, Industrial Reciprocating also called Dynamic, and Face Seals also called Axial or Flange. Radial and Dynamic seals require the presence of a diametrical clearance gap for installation.
