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 static radial seal application the o-ring is squeezed between the inner I.D. and the outer O.D. surfaces of the o-ring, with no relative motion between parts of the gland that come in contact with the o-ring. The table below lists recommended dimensions for static radial 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
