Add Lining Color to the spec. 2. Add J and R dimensions omitted in error at last revision. 3.

Commentary: The lining thickness applied to the pipe O.D.] must be accounted for by the careful control of machining and lining of both pipe and coupling. Otherwise, ovality can cause interference fits when the combined tolerances are at their extremes. Effective Date: Date of issue.
