We are one of the leading manufacturers and exporters of Bronze Fittings from India. We have been supplying Bronze Fittings to the world market for many decades. Based in Jamnagar, Gujarat, our foundry and machine shop produce high‑performance Bronze Cast and Machined Fittings from the 85‑5‑5‑5 Copper Alloy. Our comprehensive range—Elbows, Couplers, Pipe Nipples, End Caps, Tees, Crosses, Thread Converters, and Water Meter Parts—serves sanitary, plumbing, marine, and industrial applications across the USA, Europe, Middle East, and Africa.
Product Overview
Bronze Fittings are corrosion‑resistant connectors and adaptors used to join, branch, or terminate piping systems in water, steam, and oil applications. Manufactured via sand casting or precision CNC machining, our fittings offer superior dimensional accuracy, leak‑proof joints, and long service life—even in harsh environments.
