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.
Parker o ring groove design.
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.
The inherent characteristics of the groove design limit the amount of void area.
Since its initial release in 1957 the parker o ring handbook has become a fi xture on the reference shelves of engineers worldwide.
Service conditions material selector.
Parker s o ring selector is an engineering tool which offers o ring material and size selection combined in one tool.
The parker o ring handbook has been a standard reference work used by seal designers for decades.
Note that when the pressure is outward the groove outside diameter od is primary and the groove width then determines the inside diameter.
This web based mobile app offers material recommendations fluid compatibility and gland seal calculations standard sizing design analysis.
The o ring selector covers both imperial and metric standards.
Take the guesswork out of o ring design and selection with mobile inphorm.
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.
Conversely when the pressure is inward the groove inside diameter is primary.
Recommended for basic design analysis.
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.
