Abstract
A valve seal has a sealing lip and a compressible portion. The valve seal is utilized to seal a valve guide and a stem. The valve guide has a height within a predetermined range of heights and the sealing lip sealingly engages the stem. The compressible portion has at least two articulating portions with a hinge portion between the two articulating portions. The compressible portion sealingly engages the valve guide and articulates to accept the valve guide without substantially deforming the lip or interfering with the stem.
