An O-ring is defined by two dimensions and a compound: here an 11.1 mm inside diameter with a 1.6 mm cord section, moulded in nitrile. The 90 Shore A hardness is the notable attribute, a stiffer compound than the common 70 Shore grade and specified where extrusion into the gland clearance is a concern.
