Fittings
What are Pipe Fittings?
Pipe fittings are essential components used to connect, redirect, or terminate the flow of fluids in piping systems. Fittings come in various types depending on their application, pressure class, and material. We offer a complete range of industrial-grade pipe fittings including Forged Fittings, Buttweld Fittings, Bar Stock Threaded Pipe Fittings, and Investment Casting Fittings designed for high-performance fluid systems.
