Bronze Fittings are widely used in plumbing, marine, fire-fighting, oil & gas, and industrial piping systems due to their excellent corrosion resistance, pressure tightness, and durability. We are one of the leading manufacturers and exporters of Bronze Fittings from India. We have been supplying Bronze Pipe Fittings to the world market for many decades. With over three decades of expertise in Bronze casting and machining, we produce high-quality threaded, flanged, and custom Bronze fittings conforming to international standards such as ASTM, BS, DIN, EN, IS, and JIS. Our in-house foundry and CNC machining facilities ensure precise dimensional accuracy, smooth threading, and superior metallurgical integrity. Bronze fittings are known for their resistance to dezincification, saltwater corrosion, and scaling, making them ideal for marine and potable water systems. We offer both standard catalog sizes and fully customized fittings as per drawings with a typical turnaround time of 4–6 weeks.

Overview of Bronze Fittings

Bronze fittings are pipe connectors manufactured from Copper-based alloys containing Tin, Zinc, and sometimes Lead or Nickel for improved mechanical properties. Compared to ordinary Brass fittings, Bronze Pipe Fittings offer higher strength, better wear resistance, and superior corrosion resistance in seawater and aggressive environments. They are suitable for threaded (BSP/NPT), socket weld, and flanged piping systems. Bronze fittings are widely preferred for applications requiring leak-proof performance and long service life. Their non-sparking characteristics also make them suitable for hazardous environments. Bronze fittings maintain dimensional stability under temperature variations and moderate pressures. We manufacture Bronze elbows, tees, reducers, couplings, nipples, bushings, unions, and flanges for global OEMs.

Material Grades & International Standards

We manufacture Bronze fittings in multiple alloys as per global specifications:

These materials ensure compatibility across USA, UK, Europe, Middle East, and Asian markets.

Manufacturing Process of Bronze Fittings

Bronze fittings are primarily produced through Sand Casting, Shell Moulding, or Investment Casting depending on design complexity. The process includes pattern making, mould preparation, melting in induction furnaces, controlled pouring, solidification, fettling, machining, threading, pressure testing, and final inspection. CNC lathes and tapping machines ensure precise BSP, NPT, and metric threads. Hydrostatic pressure testing verifies leak-tight integrity. Surface finishes include natural Bronze, shot blasted, machined, Nickel plated, Tin coated, or epoxy coated as required. Each batch undergoes spectrometer-based chemical analysis and dimensional inspection using Vernier, micrometers, and CMM machines.

Typical Types of Bronze Pipe Fittings

Bronze fittings are manufactured in the following configurations:

• 90° Elbow

• 45° Elbow

• Tee (Equal & Reducing)

• Coupling

• Reducer

• Bushing

• Union

• Flanged Adapter

• Hose Nipple

Physical & Mechanical Properties of Bronze Fittings (Typical C83600)

Bronze fittings demonstrate excellent machinability and moderate thermal conductivity, suitable for hot and cold water systems.

Industries Using Bronze Fittings

Bronze Pipe Fittings are widely used in marine engineering, shipbuilding, offshore platforms, plumbing systems, fire protection networks, HVAC installations, irrigation systems, pump and valve manufacturing, oil & gas auxiliary systems, and water treatment plants. Their corrosion resistance in saltwater makes them particularly suitable for coastal and offshore applications.

Performance Metrics

Bronze fittings provide long service life in corrosive environments, high resistance to dezincification, reliable pressure containment, superior thread strength, and consistent dimensional tolerances up to ±0.05 mm depending on size and design. Hydrostatic pressure testing ensures zero leakage performance.
