ABSTRACT:
An API groove seal is a metal ring of cross-section like a capital letter omega arranged so that the tips of its limbs provide the sole contact with the groove base before and after compression. The central or heel region may abut on the outer side wall of the groove. A family of seals for different pressure ratings has a common profile, differing only in respect of the thickness of the limbs.
