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.
