Parker o ring groove design.

Width of ring and decreasing the area available to the entry of the gas groove depth. Recommended for basic design analysis. O ring groove design is a key consideration in the o ring selection process. Note that when the pressure is outward the groove outside diameter od is primary and the groove width then determines the inside diameter.

Both are interlinked thus ensuring the best possible combination of the calculated o ring size and material choice. Since its initial release in 1957 the parker o ring handbook has become a fi xture on the reference shelves of engineers worldwide. Browse design considerations and recommendations for static face seals metric o rings static dovetail o rings static rod piston o rings and dynamic rod piston o rings. Conversely when the pressure is inward the groove inside diameter is primary.

Design chart 4 3 explains how to design an o ring seal when the groove is cut into a fl at surface. The o ring selector covers both imperial and metric standards. Parker s o ring selector is an engineering tool which offers o ring material and size selection combined in one tool. This book contains extensive information about the properties of basic sealing elastomers as well as examples of typical o ring applications fundamentals of static and dynamic seal design and o ring failure modes.

Increased o ring squeeze reduces flow rate by increasing the length of the physical path the gas has to travel parker elastomer seals are used in many specialized vacuum applica tions from laser pumps to semicon ductor processing. The inherent characteristics of the groove design limit the amount of void area. It contains comprehensive information about the prop erties of the most important sealing elastomers typi cal o ring application examples examples of statically acting seal designs plus descriptions of conditions that may lead to o ring failure.

The parker o ring handbook has been a standard reference work used by seal designers for decades. Normally acceptable toler ance extremes wide service temperature ranges and fl uid media that cause high swell of the elastomer are conditions that cannot be tolerated in this type of groove design.
