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.

Before ordering CNC turned stainless steel adapters from Kunshan JST Industry Co. Ltd., verify material certification for 304 stainless steel, including chemical analysis and mechanical properties. Request a first-article inspection report showing measured dimensions, thread fit, and surface roughness. Do not rely on supplier claims without documented proof.
Confirm lead time for both samples and production runs, as stated at 15 and 30-45 days respectively. Clarify Incoterms such as FOB Shanghai or EXW Kunshan, and payment terms like T/T or L/C. Packaging is specified, but buyers should confirm if wooden cases meet ISPM-15 standards for international shipping.
Conduct incoming inspection using thread gauges, calipers, and surface roughness testers. Check for surface defects, burrs, and correct thread engagement. Retain samples for traceability and request a Certificate of Conformance with each shipment. For medical use, ensure compliance with ISO 13485 and request biocompatibility data if applicable.
