ABSTRACT:
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. An upper washer is mounted on the stem portion of the stem fitting and is maintained thereon through the use of a nut which is threadably mounted on the upper end of the stem fitting. A locking mechanism is provided which prevents the inadvertent loosening of the nut with respect to the stem fitting.
