X-profile NBR ring listed with an 18 × 1.5 example size.

This supplier entry identifies a black nitrile X-ring rather than a conventional round-section O-ring. Its example designation includes 18 × 1.5 and a 70 compound mark. The page lists fixed, bore, shaft and dust-sealing applications and offers size changes. Selection should retain the X-shaped section when comparing groove dimensions.
