Abstract
An impact resistant seal includes an annular body extending between a first end and a second end. The annular body includes a first anchor formed on the first end and a second anchor formed on the second end. The impact resistant seal includes an elastomeric section having an exterior surface which extends between the first anchor and the second anchor. The elastomeric section is expandable and contractible in response to movement of the first anchor relative to the second anchor. The impact resistant seal includes a plurality of protrusions extending radially outward from the exterior surface and extending circumferentially around the elastomeric section. Adjacent ones of the plurality of protrusions are spaced apart from one another by a predetermined spacing magnitude configured to accommodate the movement of the first anchor relative to the second anchor.
