We help you find reliable manufacturers in China that produce brass pipe couplings. Our manufacturers can deliver high-quality, functional, and durable pipe couplings at affordable prices. We can customize the products according to your requirements. We assure you of the highest quality in every batch that you order.

Typical materials: CW617N and various other grades of brass

Brass is very versatile and can be molded into a range of shapes, widths, and sizes. It is extremely durable and has a long service life. Brass is also corrosion resistant and can withstand very high temperatures. CW617N has excellent hot forming properties and very high machinability.

CW617N is mostly preferred because:

• It is resistant to corrosion
• Has excellent high forming properties
• Has a high machinability rating
• Easier to braze and solder

Material composition:

• 58% copper
• 2% lead additive
• 0.3% maximum iron
• 0.7% maximum impurities
• Remaining zinc

Hot-working temperature range: 650-775°C (1202-1427°F)

Tensile strength: 380 MPa (55 ksi)

Common MOQ: 100 to 10,000 pcs

Common parts or standardized parts usually have higher MOQs. While MOQs are negotiable, buyers are advised to be reasonable about the numbers.

Manufacturing methods: Hot forged and CNC machining

• Hot forging is used to manufacture the components to improve ductility, mechanical characteristics, and surface appearance.
• To fit the client’s design and specifications, the components are then machined further using a CNC machine.
• The manufacturer ensures precision with the components and takes special care for the intricate parts.

Manufacturing cluster area: Ningbo (Zhejiang province)

Ningbo is a major industrial hub in China and is one of the oldest cities in the country. It is located in the northeast Zhejiang province of China. The port of Ningbo-Zhoushan is one of the busiest in the world.

The sectors of textiles, garments, home electric appliances, stationery, plastic machines, auto parts, and high-end molding are thriving in Ningbo. The textile industry in the city accounts for 12% of the total industry output of the city.  The electric home appliance sector is noteworthy as it houses over 3,000 manufacturers and nearly 10,000 factories producing electrical appliance parts.

Ningbo is a significant auto parts production center in China, with over 2,300 manufacturers. The city is also called the Stationery Capital of China, housing more than 8,000 stationery manufacturers. The mold industry is also very prominent in Ningbo, with over 3,000 manufacturers.

Application: Plumbing, heating, and hydraulics

A coupling is a very short tube with sockets on one or both ends. It is used to join, weld, braze, or solder two pipes or tubes together. They offer tight, durable seals and also have flexible joints that do not require special tools. They are also extremely helpful for piping modifications.

You can find pipe couplings wherever pipe systems are used. Plumbing, chemical and petrochemical industries, all use pipe couplings. They are used in power plants for cooling return pipes, lubrication pipes, compressed air-lines, and firefighting lines. Pipe couplings are utilized in plant maintenance, water and gas supply systems, industrial plants, civil engineering, building construction, design work, and other machinery.

Common issues: Dimensional control

Our manufacturers in China ensure that all components match the original design and specifications given by you.

Quality Control

• CMM inspection to test the accuracy of the manufactured components
• Assess jigs and fixtures to replicate manufactured products with consistent quality
