In 1903:
During August 1903, Plumbers, Gas Fitters, and Steamfitters UA Local 444, Oakland, CA was chartered with only thirty-nine members. On June 1, of the same year the American Federation of Labor (A.F of L.) revoked the charter of the National Association of Steam and Hot Water Fitters and Helpers of America, leaving the United Association as the only recognized international union with the right of control and jurisdiction over the entire pipe trades industry.

May 1, 1914:
Steamfitters UA Local 342, Oakland, CA was chartered. Twenty-one members who disbanded from Locals 590, 441, 442, 444, 343, 387, 217, 230, 166, and 19 came together to form a new charter. Local 342 belonged to what was known in the Bay Area and to our international body as the Bay District American Federation of Labor (A.F. of L).
