O'ring Groove Design As important as the o'ring seal itself is the groove that the o'ring seats into The groove must be designed to accommodate not just the o'ring size, but also its intended usage;Piston seal (figure 36) the ORing is inserted in a seat machined on the component which constitu tes the shaft of the assembly, and the preloading deformation for the seal is of a radial type;The tendency of an Oring to return to its original shape when the cross section is deflected is the basic reason why Orings make excellent seals The squeeze or rate of compression is a major consideration in Oring seal design Elastomers may take up the stackup of tolerances of the unit and its memory maintains a sealed condition

O-ring shaft seal design-Be it dynamic or static operation, radial or axial loading, vacuum or high pressure An engineering design flaw in the Oring seal on one of the solid rocket boosters caused a leak of hot gas that eroded the external fuel tank and led to the explosion The leak was exacerbated by unusually cold weather the night before the launch, which caused the Oring to lose elasticity and form a bad seal Almost no one realized that this might be a problem until it

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;An Oring has proved to be a practical rotary shaft seal in many applications With the correct design, Parker ORing rotary seal compound N, will provide satisfactory service at surface speeds up to 1500 feet per minute The design conditions are most critical for rotary seals, as would be expected Relatively high durometer compounds, Some installation lubricants can dry and cause seals to stick to the shaft, leading to high friction or seal twisting Don't Underestimate the effects of rapid stretch on sealing
