Male-Threaded Size Transition Connector

The galvanized male reducing nipple is designed to connect two female-threaded fittings of different sizes in a straight-line configuration.
It features male threads of different sizes on each end, allowing direct connection between mismatched female-threaded components without additional adapters.
A customer in Malaysia required a solution to connect a DN50 female-threaded pump outlet to a DN25 female-threaded pipe inlet in a compact installation space. Standard reducers and additional fittings could not provide a direct solution. By using our male reducing nipple, the connection was completed with a single component.

This fitting integrates both size reduction and connection functions into one component, reducing the need for multiple fittings and simplifying installation.
It is suitable for threaded piping systems where space is limited and direct size adaptation is required.
Jianzhi Group manufactures these fittings and holds over 100 national patents. The company has also participated in drafting more than 20 national standards in China.
The minimum order value is 10,000 RMB, and mixed sizes are acceptable within a single order.
OEM branding is available upon request.

The hot-dip galvanized coating provides long-term corrosion resistance for water, gas, and low-pressure piping systems.
Each unit undergoes full inspection prior to packaging, including thread quality checks on both ends.
Third-party inspection is welcome.
Warranty support is provided. If any issue occurs upon arrival at your port, please provide photos for verification. Replacement or refund will be arranged accordingly.
Payment terms: 30% deposit, 70% balance before shipment. Available terms include EXW, FOB, and DDP.
