Black NBR and EPDM O-Rings — Standard Sizes and Wear Requirements

Black NBR (nitrile) and EPDM O-rings are separate material options for standard-size sealing applications. Specify the AS568 dash number or metric inner diameter and cross-section, dimensional tolerances and compound hardness. Black color identifies an appearance requirement; it does not distinguish the polymer or establish wear performance.

For a moving seal, provide speed, stroke, lubrication, surface finish and operating clearance along with fluid and temperature. Review the selected NBR or EPDM grade against these conditions and define abrasion or wear-test requirements where needed. For a static gland, specify squeeze and compression-set criteria. Matching size and color do not establish interchangeability between NBR and EPDM compounds.
