Solutions to Thermal Expansion of Aluminum Seal Housings 841147

The success of an elastomeric seal is highly dependent upon the temperature variation in the application. The sealing at the O.D. of the seal is often overlooked, especially when steel O.D. seals are pressed directly into an aluminum bore.
There are both theoretical methods for calculating seal/bore interference and actual hardware tests which can be used to accurately determine seal/bore interference with varying temperatures.
