2MM CS X 17.5MM ID BLACK BUNA 70D

Ordered as H2X17.5, this is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 17.5 mm (0.689 in), a cross section of 2 mm (0.079 in), and an outside diameter of 21.5 mm (0.85 in). The o-ring compresses into its gland to block fluid or gas migration across a joint.
