Due to the number of interacting forces, it is STRONGLY RECOMMENDED THAT YOUR ELASTOMER SELECTION BE RIGOROUSLY TESTED IN THE ACTUAL APPLICATION, performance assumptions must be checked so that you are certain that all variables have been carefully considered
In a dynamic rotary seal applications a turning shaft protrudes through the I.D. of an o-ring, the o-ring then becoming a seal. The table below lists recommended dimensions for dynamic rotary seal glands by AS-568A o-ring dash numbers. For more information please contact one of our project managers at1.800.227.3539 ext.19
