This precision CNC turning brass fitting is custom manufactured from H59 brass material as brass threaded coupling with flat surface, also named brass male thread reducing adapter and cnc turning brass threaded stud.

All structural features including through inner bore, full external male thread and flat hexagonal flange step are one-step CNC turning molded without secondary complex milling. After core lathe processing, we conduct full deburring to remove sharp edges, ultrasonic cleaning to wipe off cutting oil, and 100% dimensional inspection before delivery.

As a professional OEM custom machining manufacturer, we accept customer’s drawings, samples and custom dimension requirements to produce personalized brass pipe connector with flat for all kinds of fluid control, sensor, instrument assembly matching needs. The raw H59 brass delivers excellent ductility, corrosion resistance and thread machining performance for long service life of brass threaded coupling fittings.

• Fluid pipeline connecting fittings for water, gas, liquid conveying equipment
• Instrument & sensor internal assembly threaded connection parts
• Household plumbing hardware transition connectors
• Automation equipment miniature pipeline adapter components
• Medical equipment non-corrosive brass threaded coupling accessories
• Electrical equipment cooling pipeline transition fittings

As a professional custom CNC machining manufacturer, we provide full OEM & ODM custom service for this brass threaded coupling with flat surface:

• Custom processing based on customer’s technical drawings, CAD files or physical samples.
• Custom material replacement (H62 brass, copper alloy) upon demand.
• Custom adjusted length, thread diameter, flange size & inner hole aperture.
• Custom surface treatment: brass polishing, anti-rust passivation, oil sealing.
• Custom tolerance upgrading for ultra-precision matching scenarios.
• Custom packaging & private labeling service for bulk order clients.
• Small batch trial production & mass volume production support.

• One-step CNC turning forming avoids multi-process assembly errors, solving loose thread matching & dimensional offset of split machined parts.
• H59 brass raw material resists daily fluid corrosion, solving easy rust & short service life issue of iron alloy connectors.
• ±0.01mm high precision tolerance eliminates assembly gap, solving leak risk for pipeline connection.
• Flat positioning flange surface for stable installation, solving slipping & unstable fixing problem during equipment assembly.
• Full automatic deburring treatment, no sharp edges to scratch sealing gaskets, solving fluid leakage caused by damaged gaskets.
• In-house full inspection before shipment, solving inconsistent product size & defective delivery from small machining workshops.
• Custom OEM service flexible for unique equipment specs, solving difficulty finding standard fittings for non-universal equipment.

• Raw Material Inspection: Test H59 brass alloy composition before production to ensure material compliance.
• In-process First Article Inspection (FAI): Verify sample dimension, thread pitch & flat flange size before mass production.
• Mid-production Random Sampling: Periodically check thread precision, inner hole straightness & surface burr status during CNC turning.
• Post-processing Full Inspection: 100% dimensional measurement for length, diameter, thread size; visual check for burr & surface defect after cleaning.
• Packaging Final Audit: Double-check product quantity and appearance before packing to prevent mixed defective goods.
• Complete inspection report available for OEM bulk order clients.
