About Latrobe Foundry Machine & Supply
About Latrobe Foundry Machine & Supply
Latrobe Foundry Machine and Supply Company was founded in 1933 by Louis C. Steiner in Latrobe, Pennsylvania as a cast iron and steel manufacturing and machining operation. The company formed an aluminum division in 1963 to manufacture threaded aluminum pipe fittings, nipples, and flanges, and over time shifted its focus almost entirely to aluminum production.
The company remained family-owned for more than 85 years, with later generations of the Steiner family running day-to-day operations, and opened a second manufacturing facility in Pasco, Washington in 2019 to better serve customers on the West Coast. Its product line covers threaded and flanged aluminum pipe fittings alongside custom castings and 3D printing services for pattern and prototype work.
Latrobe Foundry's aluminum fittings are widely specified where corrosion resistance and lighter weight matter compared with standard steel or malvern fittings, including industrial piping, marine, and specialty fabrication applications. ChatMRO indexes the Latrobe Foundry catalog so buyers can search by fitting type, pipe size, or thread configuration to find matching parts quickly.
