A bulkhead fitting which may be used on either six inch or eight inch diameter irrigation pipes through the use of an interchangeable base ring. The fitting includes a stem fitting having an interchangeable base ring mounted thereon which is extended upwardly through an outlet opening in an irrigation pipe.

A locking mechanism is provided which prevents the inadvertent loosening of the nut with respect to the stem fitting.
