Import Cnc Turned Stainless Steel Adapter — Buy in Bulk from Supplier in China

CNC turned stainless steel adapters from Kunshan JST Industry Co. Ltd. are precision-machined components designed for fluid or mechanical connection systems, with material specified as 304 stainless steel and thread specification G 3/4. Tolerances are held to ±0.02 mm, and the design is optimized for applications requiring corrosion resistance and dimensional stability. Production uses CNC Swiss-type and conventional lathes to achieve consistent geometry across batches.

The use of 304 stainless steel provides good resistance to oxidation and mild corrosion, making it suitable for medical, food, and instrumentation environments. The adapter's geometry includes external threads, stepped diameters, and internal bores, typical of compression fittings. Surface finish is not specified, but standard turning processes produce Ra values between 0.4 and 1.6, which may require polishing for hygiene-sensitive uses.

These adapters are primarily used in medical devices, food processing equipment, and precision instrumentation. The supplier states a sample lead time of 15 days and mass production lead time of 30 to 45 days. Packaging consists of individual PE bags, grouped in 20-piece lots, with cartons of 15 kg and wooden cases for export. Buyers must confirm exact packaging requirements and delivery terms before order placement.

Kunshan JST Industry Co. Ltd. is located in Kunshan, Jiangsu, China, and operates a dedicated CNC turning department with 20 NC lathes and 6 CNC Swiss-type machines. The company employs six engineers and three full-time quality control personnel, all with over ten years of experience in precision machining. The listing does not mention company founding date, revenue, or certifications such as ISO 9001 or ISO 13485.

The supplier specializes in components for medical devices, aerospace, food equipment, and automotive applications. It has internal inspection capabilities using calibrated tools, but provides no documentation of audit reports or material traceability systems. Buyers should request material test reports and first-article inspection data before committing to production runs.
