Steel Flanged Weld-on Tank Fitting (Stamped)

USA-made NPT steel weld flanges stamped from 1018 CR flat bar. Sizes 1/8"–2" NPT. Common uses: fuel, hydraulic, and water tanks.

  • Made in USA
  • Quality-checked with L1 thread gauge
  • Not replaced after welding

NPT sizes refer to the pipe that threads into the fitting. Threads have a 1.8° taper — male fittings typically tighten 1 turn or less past hand-tight. Use appropriate thread sealant.
