Abstract
A Pitman shaft boot seal designed for a static sealing application with one sealing surface compressed against the Pitman arm and the other sealing surface compressed against the steering gear housing. The sealing surfaces are held in place by a compression spring located inside the boot seal. The cylindrical portion of the boot seal is formed with a plurality of identical, equally spaced-apart, parallel, hollow ribs parallel to the axis of the Pitman shaft and extending around the entire circumference of the seal. The ribs allow the boot seal to twist as the Pitman arm moves arcuately, without breaking the static seal at the sealing surfaces.
