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 crush seal applications the o-ring is squeezed at an angle relative to its cross section. In these applications the o-ring is completely confined and pressure deformed within a 45ยบ triangular gland, as depicted. The table below lists recommended dimensions for static crush 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
