Our precision CNC machining custom brass threaded fitting is precision engineered for fluid systems, instrumentation, measurement equipment, and custom hardware applications where excellent corrosion resistance, reliable sealing, and custom specifications are critical. Each brass threaded fitting is manufactured on advanced CNC machining centers with 4-axis and 5-axis capabilities, maintaining tolerances as tight as +/-0.01mm to ensure proper thread engagement, reliable sealing, and consistent performance.
This custom fitting features precision fine external threads for secure connection, a transverse cross-bore for fluid passage or pin location, a large external hex head for wrench tightening, and a precision cylindrical base section for system integration. Our precision CNC machining capabilities enable complex geometries including fine threads, cross-bores, hex profiles, and cylindrical features - all machined from solid brass billets for maximum accuracy and material integrity.
Precision CNC machining delivers exceptional advantages for custom brass fitting manufacturing. Brass material offers excellent machinability, superior corrosion resistance, and good thermal conductivity - making it ideal for fluid systems, instrumentation, and decorative applications. The precision machining process achieves superior surface quality with mirror-polished finishes reaching Ra 0.2-0.4um for optimal sealing performance.
This brass threaded fitting is manufactured from high-quality C36000 brass (or custom brass alloys per requirements), selected for its excellent machinability rating of 100% (the standard against which all other metals are rated), corrosion resistance, and attractive golden appearance. The precision CNC machining process ensures all features are machined to exact specifications with tight tolerances and excellent repeatability across production runs.
Our ISO 9001:2015 certified quality management system ensures consistent quality across every production run following GB/T 1804-2000 standard with strict tolerance control. Each precision CNC machined brass threaded fitting undergoes comprehensive dimensional inspection using coordinate measuring machines to verify thread accuracy, hex head dimensions, cross-bore positioning, and geometric tolerances. Surface finish and material properties are verified to ensure specifications are met. Complete inspection reports and material certificates are provided with every shipment.
These precision CNC machining custom brass threaded fittings serve applications across fluid system fittings, instrumentation connectors, measurement equipment adapters, pneumatic system fittings, decorative hardware components, marine equipment fittings, plumbing fixtures, and custom OEM hardware. Brass material is particularly suited for applications requiring corrosion resistance, attractive appearance, and excellent machinability for complex custom designs.

FAQ
Q: What brass materials do you use for custom fittings?
A: We primarily use C36000 brass (free-machining brass) for its excellent machinability and corrosion resistance. We also work with C26000 brass, C27200 brass, C28000 brass, and custom brass alloys per your specific requirements. All brass materials comply with ASTM standards and come with material traceability certification.
Q: What threaded fitting sizes can you manufacture?
A: We manufacture precision CNC machining custom brass threaded fittings from compact instrumentation connectors to large industrial fittings. Our CNC capabilities accommodate fitting sizes from 10mm to 200mm with custom thread specifications (M3 to M36, BSP, NPT, UNC/UNF) and hex dimensions based on your requirements.
Q: Can you produce custom thread specifications?
A: Yes, we specialize in custom thread specifications including metric threads (M3 to M36), imperial threads (UNC/UNF), BSP, NPT, and custom thread profiles. Our precision CNC machining achieves thread tolerances within 6g/6H following ISO standards for reliable sealing and connection.
Q: What surface finishes are available for brass fittings?
A: We offer various surface finishes including mirror-polished (Ra 0.2-0.4um), satin finish, brushed finish, and custom textures. Brass fittings can also be supplied with clear protective coating, nickel plating, or chrome plating upon request for enhanced corrosion resistance and decorative appearance.
Q: What is the typical lead time for custom brass fittings?
A: Prototype samples: 5-10 days. Small batch (10-100 pcs): 2-3 weeks. Medium batch (100-1000 pcs): 3-5 weeks. Large production (1000+ pcs): 5-8 weeks. Fast delivery and consistent quality ensure high customer satisfaction. Rush orders can be accommodated upon request.
Q: What tolerances can you achieve on brass threads?
A: We achieve thread diameter tolerances within +/-0.01mm and thread pitch accuracy within 0.02mm with precision CNC machining. Our advanced CNC centers maintain tight geometric tolerances, achieving tolerances down to 0.01mm following GB/T 1804-2000 standard for critical thread features.
Q: Do you provide custom design and engineering support?
A: Yes, our experienced engineering team provides comprehensive custom design support including DFM analysis, material selection guidance, tolerance optimization, and manufacturability feedback. We work closely with you from initial concept through final production to ensure optimal results.
Q: Can you support both prototypes and mass production?
A: Yes, we offer flexible manufacturing from single prototypes for design validation through to high-volume production runs. Our precision CNC machining capabilities reduce lead times while maintaining quality and consistency across all production volumes, from 1 piece to 10,000+ pieces.
Q: Do you provide material certificates and inspection reports?
