Abstract

A seal includes an annular seal body formed of an elastomeric material and has opposing first and second circumferential surfaces and a sealing projection extending radially from the first circumferential surface. The projection has a frustoconical primary sealing surface with first and second axial ends and an axial length between the first and second ends. The projection is sealingly engageable with the inner surface of the outer member when the seal body is coupled with the inner member, such that substantially the entire axial length of the primary sealing surface is disposed against the inner surface of the outer member. Alternatively, the projection is sealingly engageable with the outer surface of the inner member when the seal body is coupled with the outer member, such that substantially the entire axial length of the primary sealing surface is disposed against the outer surface of the inner member.
