Our precision CNC machining custom mini brass threaded fitting is precision engineered for compact sensor connections, small instrumentation systems, miniature fluid devices, and precision custom hardware applications where small size, fine details, and reliable sealing are critical. Each mini 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 in compact installations.
This compact fitting features an extended precision tubular tip section for sensor integration or small-bore connection, a central hex body for wrench tightening and assembly alignment, and precision fine external threads at the base for system mounting. Our precision CNC machining capabilities enable complex miniature geometries including fine threads, hex profiles, tubular tips, and small-diameter features - all machined from solid brass billets for maximum accuracy despite the compact size.
Precision CNC machining delivers exceptional advantages for custom mini brass threaded fitting manufacturing. Small-size components demand exceptional precision since even minor deviations are magnified relative to overall dimensions. Our precision machining process achieves superior surface quality with mirror-polished finishes reaching Ra 0.2-0.4um, critical for proper thread engagement and sealing in miniature applications where standard surface finishes would compromise performance.
This mini brass threaded fitting is manufactured from high-quality C36000 free-machining brass (or custom brass alloys per requirements), selected for its excellent 100% machinability rating, corrosion resistance, and ability to hold fine tolerances in small dimensions. The precision CNC machining process ensures all miniature 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 mini brass threaded fitting undergoes comprehensive dimensional inspection using coordinate measuring machines and optical comparators to verify fine thread accuracy, hex body dimensions, tip section concentricity, 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 mini brass threaded fittings serve applications across mini sensor connection fittings, small instrumentation mounting adapters, compact pneumatic system fittings, miniature valve assemblies, precision instrument hardware, medical device small fittings, optical equipment brass components, and micro-fluidic device fittings. The compact size is particularly suited for installations with limited space, miniaturized equipment, and precision instruments requiring reliable small-scale connections.
We support your complete custom hardware development cycle with flexible manufacturing options from prototype to mass production. Our precision CNC machining capabilities accelerate custom hardware development. Validate designs with rapid prototypes for fit and function testing, refine through small batch testing for performance validation, and scale to high-volume production for commercial manufacturing. Our experienced engineering team provides DFM feedback to optimize custom mini fitting designs for manufacturability at small scales, sealing performance, and cost. Fast delivery and consistent quality ensure customer satisfaction.
A: We manufacture precision CNC machining custom mini brass threaded fittings from ultra-compact 5mm overall length to standard 100mm sizes. Our CNC capabilities accommodate miniature features including M2 to M16 threads, hex bodies from 4mm across-flats, and tip sections as small as 1mm diameter based on your specific requirements.
A: We primarily use C36000 brass (free-machining brass) for its 100% machinability rating, essential for miniature components. We also work with C26000, C27200, C28000 brass, lead-free brass, and custom brass alloys per your requirements. C36000 is particularly recommended for mini fittings because it machines cleanly and holds tight tolerances in small dimensions.
A: Mini brass fittings present unique challenges since small absolute tolerances become significant relative to overall size. Our precision CNC machining achieves thread diameter tolerances within +/-0.01mm and concentricity within 0.01mm even on components under 20mm length. We use specialized micro-machining tooling and precision fixturing to maintain accuracy at miniature scales.
A: We produce various miniature thread specifications including metric threads (M2 to M16), imperial threads (#0-80 to 1/4-20), BSP, NPT, and custom thread profiles. Our precision CNC machining achieves thread tolerances within 6g/6H even on small threads. We can produce both external and internal threads on mini fittings as required.
A: Yes, we specialize in customizing tip section dimensions, hex body across-flats, thread specifications, and overall geometry for mini fittings. Our DFM team optimizes designs for your specific small-device integration requirements, ensuring manufacturability at miniature scales while maintaining required tolerances and sealing performance.
A: We offer various surface finishes including mirror-polished sealing surfaces (Ra 0.2-0.4um), satin finish, natural brass finish, nickel plating, gold plating, and clear protective coating. Mirror-polished sealing surfaces are particularly important for mini fittings to ensure reliable sealing at small scales where surface imperfections could cause leaks.
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 for urgent prototype needs.
A: We achieve miniature feature tolerances within +/-0.01mm and concentricity within 0.01mm with precision CNC machining. Our advanced 5-axis CNC centers with specialized micro-tooling maintain tight geometric tolerances on small features following GB/T 1804-2000 standard, achieving precision that meets demanding miniature application requirements.
A: Yes, every shipment includes complete documentation: material certificates (mill certificates with full traceability), dimensional inspection reports using CMM and optical comparator data, surface finish verification, thread gauge reports, and full quality records. For critical applications, we also provide leak testing and additional certifications.
