The OR 20 JM is a critical sealing component for the 20-inch, multi-piece combat wheels found on military vehicles like the LMTV, MTV, and MRAP. The 1/4" measurement refers to the cross-section thickness of the O-ring cord. An OR 20 JM is significantly thicker than the older M35A2 style O-rings, which were often 3/16 inch. If yours looks noticeably beefier than a standard O-ring, it is likely the 1/4 inch JM variant.
