Abstract
A seal has a seal body with an axis and axial-facing surfaces. The seal body is configured to be mounted to a tubular member, and seal between the tubular member and a second tubular member. A visual indicium can be located on only one of the axial-facing surfaces. Prior to assembly of the tubular member and the second tubular member, the visual indicium is configured to be visible to a user after being correctly mounted to the tubular member without the user physically contacting the seal body.
