Bronze Threaded Fittings Manufacturer & Exporter India | BSP NPT Bronze Pipe Fittings

We are one of the leading manufacturers, suppliers and exporters of Bronze Threaded Fittings from India. We have been supplying Bronze threaded fittings and pipe fittings to the world market for 3 decades. Our Bronze threaded fittings are precision-machined components used across industrial, marine, and plumbing applications where superior corrosion resistance, strength, and durability are paramount. Manufactured from high-quality Bronze alloys — primarily Leaded Tin Bronze, Phosphor Bronze, and Naval Brass Bronze — our fittings meet the demanding requirements of environments exposed to seawater, chemicals, steam, and high-pressure fluids. We hold ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certifications, ensuring that every fitting dispatched from our facility complies with the highest international quality and safety standards. With extensive global exposure, our Bronze threaded fittings are exported to the USA, UK, Germany, Australia, Canada, the Middle East, and Southeast Asia, serving OEM manufacturers, distributors, and engineering contractors who demand consistent quality and reliable supply chains.

Our manufacturing facility in India is equipped with CNC turning centres, multi-spindle automats, hydraulic forging presses, and thread-rolling machines, allowing us to produce Bronze threaded fittings across a wide range of sizes — from ⅛ inch to 4 inches BSP, NPT, and metric threads. We offer custom sizes, thread forms, and special configurations based on customer drawings and specifications. With a typical turnaround time of 4–6 weeks for standard orders, we also offer expedited production schedules for time-critical projects. Our ability to customize packaging — including customer-branded cartons, individual polybag labelling, and custom markings — makes us a preferred sourcing partner for importers and distributors worldwide.

Material Grades — Bronze Threaded Fittings

Bronze is an alloy of Copper and Tin, often with additional elements such as Lead, Phosphorus, Aluminium, or Silicon to enhance specific properties. The material grade selection depends on the application environment, pressure rating, and required mechanical properties.

Manufacturing Processes

Our Bronze threaded fittings are manufactured using a combination of hot forging, sand casting, investment casting, and CNC precision machining depending on the fitting type, size, and quantity. For standard elbow, tee, coupling, and union fittings in sizes up to 2 inches, hot forging followed by CNC machining gives the highest density and pressure integrity. Larger fittings and specials are typically produced by sand casting or lost-wax investment casting, followed by precision machining of sealing faces and threaded bores.

Key processes include: Hot forging (for dense, void-free fittings in small to medium sizes), sand casting and green sand moulding (for complex geometries and larger sizes), investment casting / lost wax process (for intricate shapes with tight tolerances), CNC turning and milling (for machined surfaces, faces, and thread cutting), thread rolling and thread cutting (BSP, NPT, metric), barrel finishing and shot blasting (for surface preparation), electroplating — nickel, tin, chrome (for corrosion protection and aesthetics), and hydrostatic pressure testing (per ASME B16.15, BS 143, IS 778 standards).

International Standards for Bronze Threaded Fittings

Our Bronze threaded fittings are manufactured in accordance with the following international standards: BS 143 & BS 1256 (Malleable cast iron and cast copper alloy threaded pipe fittings), ASME B16.15 (Cast Copper Alloy Threaded Fittings — Classes 125 and 250), IS 778 (Copper Alloy Gate, Globe and Check Valves), DIN 2999 (Pipe threads — dimensions), ISO 7-1 (Pipe threads — taper threads for joint sealing), JIS B 0203 (Taper pipe threads, Japanese standard), and ASTM B584 (Standard specification for Copper alloy sand castings).

Industries Using Bronze Threaded Fittings

Bronze threaded fittings serve a broad range of industries owing to their exceptional corrosion resistance, strength, and non-sparking properties. The marine and shipbuilding industry relies heavily on Bronze pipe fittings for sea-cooling systems, bilge systems, and fuel lines aboard vessels. The oil and gas sector uses Bronze fittings in offshore and onshore pipelines where dezincification resistance is critical. Fire protection systems widely use Bronze threaded elbow fittings and tee fittings as they meet the stringent requirements of NFPA and FM standards. The chemical and petrochemical processing industry uses Bronze fittings for handling non-oxidising acids, alkalis, and saline fluids. Hydraulic and pneumatic systems, potable water installations, HVAC systems, power generation plants, food and beverage processing equipment, and defence and naval applications all extensively rely on Bronze threaded pipe fittings sourced from manufacturers like us.

Air freight options are available for urgent shipments.

Performance Metrics

Why Choose Us for Bronze Threaded Fittings?

With over three decades of manufacturing and export experience, Cable Glands India has built a reputation as a trusted source for precision Bronze threaded pipe fittings across five continents. Our global exposure — having served customers in more than 40 countries — means we understand international standards, packaging requirements, documentation norms (material test certificates, country of origin, MSDS), and compliance needs of buyers in the USA, Europe, and Australia. Here is what truly sets us apart:

Unmatched Customisation Capability: We design and manufacture Bronze fittings as per customer drawings, 3D models, CAD files, or physical samples. Non-standard thread forms, special face configurations, unique markings, and alloy modifications are handled in-house without subcontracting. This ensures consistent quality and faster turnarounds.

Flexible Production: Whether your order is 500 pieces or 500,000 pieces, we accommodate both. Our flexible manufacturing scheduling means small-batch prototype orders receive the same attention as large production runs.

Certified Quality System: Our ISO 9001:2015 quality management system governs every process — from incoming material inspection and in-process checks to final hydrostatic testing and dimensional verification using CMM. Material test certificates (MTCs) and third-party inspection by SGS, Bureau Veritas, or TÜV can be arranged on request.

Superior Communication and Customer Support: We assign a dedicated account manager to every customer. Our response time for technical queries, quotations, and order updates is within 24 hours. Regular production updates, pre-shipment photos, and packing lists are standard practice. Customers routinely commend our proactive communication — something that differentiates us sharply from other Indian exporters.

Customised Packaging with Customer Branding: We offer packaging with the customer’s logo, brand name, part numbers, and barcodes. This white-label packaging service is available for distributors and importers who market under their own brand.

Competitive Pricing with Consistent Quality: India’s manufacturing advantage combined with our process efficiency allows us to offer pricing that is competitive against European, American, or Chinese alternatives — without compromising on alloy purity, dimensional accuracy, or surface finish.

Packaging and Shipping

Bronze threaded fittings are individually wrapped in anti-corrosion polybags, then packed in card partitioned trays or cardboard cartons. Heavier fittings and large-size items are packed with foam cushioning. Carton boxes are strapped and palletised for container shipment. We ship via sea freight (FCL and LCL), air freight, or courier depending on quantity and urgency. Export documentation includes commercial invoice, packing list, bill of lading, certificate of origin (CoO), and material test certificate (MTC). We have experience exporting to ports in the USA, UK, Germany, Netherlands, UAE, Australia, and Singapore.
