About Us

Steamfitters' Local Union 420 has jurisdiction over all or parts of ten counties in southeastern Pennsylvania for the installation and service of mechanical systems.  We service the entire state for gas pipeline distribution.  In the area of instrumentation calibration, this "educational local" has jurisdiction over four Northeast states (PA, NJ, DE, NY).  Members of the local are proud of their craft, proud of their city, and determined to do everything they can to insure the city and its surrounding suburbs will continue to grow and prosper.

Members of Local 420 are career-oriented individuals, proud of their heritage, their superior training and the opportunities offered in their field. Apprentices graduate to become journeyworkers.  Journeyworkers become foremen, general foremen, superintendents, estimators, project managers, or owners of mechanical construction and service companies.  Virtually all graduates of our apprenticeship program stay in their trade, even though many now have management positions with contractor organizations. The sky is the limit for graduates of the "educational local." 

Local 420 is taking care of its members, families, and the community through youth programs, scholarship funds, specialized educational programs, active participation in local and regional affairs, and vested retirement and health programs to protect its members.  Local 420 contributes to future employment opportunities and supporting efforts to revitalize Philadelphia in order to attract new businesses and new employment opportunities for all residents of this metropolitan area.
