· Product Overview

• A hexagonal base (for secure wrench tightening)
• External male threads (for connection to female ports)
• Internal female threads (for mating with male fittings)
• A precision-machined sealing shoulder (for leak-free performance)CNC-machined to ultra-tight tolerances and finished with a passivated polished surface, this adapter delivers reliable, long-lasting performance in demanding industrial, medical, and fluid-handling applications.

· Core Specifications

Materials & Performance

Manufacturing Standards

• Certification: ISO 9001-Certified
• Key Processes: CNC Turning (hex base + threaded profiles) → Precision Tapping (internal threads) → Deburring → Surface Passivation → Thread Gauge Inspection
• Standard Parameters:
  • External Thread: M16 (customizable to Metric/Imperial specs like NPT/BSPP)
  • Internal Thread: M12 (matched to external thread for conversion)
  • Hex Base Width: 24mm (for standard wrench compatibility)
  • Dimensional Tolerance: ±0.01mm (ensures leak-free thread fit)
  • Surface Finish: Passivated polished (scratch-resistant, rust-proof, and smooth for low-friction installation)

· Application Scenarios

• Industrial Fluid Systems: Hydraulic/pneumatic line adapters, coolant system fittings, and chemical transfer connectors.
• Food & Beverage Processing: Sanitary pipeline adapters, packaging machine fluid fittings, and brewing equipment connectors (FDA-compliant).
• Medical & Laboratory Equipment: Diagnostic instrument fluid lines, sample transfer adapters, and surgical device fittings.
• Automotive & Marine: Engine coolant line adapters, fuel system connectors, and boat hardware fittings (corrosion-resistant).
• HVAC & Plumbing: Refrigeration line adapters, water pipe connectors, and compressed air system fittings.

· Production Process Introduction

1. Raw Material Sourcing: Procure certified 304/316 stainless steel round bars (traceable to quality standards) and cut to blank length.
2. CNC Turning: Use high-precision CNC lathes to machine the hexagonal base, external male threads, and sealing shoulder in a single setup for maximum concentricity.
3. Precision Tapping: Create internal female threads with high accuracy to ensure leak-free mating.
4. Deburring & Finishing: Remove sharp edges from threads and hex corners to prevent assembly damage and ensure safe handling.
5. Surface Passivation: Apply a chemical passivation treatment to enhance stainless steel’s natural corrosion resistance.
6. Quality Inspection: Verify thread fit with gauges, perform pressure testing for leak resistance, and confirm dimensional accuracy via CMM scans.

· Packaging and Shipping Methods

• Packaging:
  • Individual Units: Sealed in anti-scratch plastic bags and labeled with thread specifications to prevent damage and ensure traceability.
  • Bulk Orders: Packed in foam-lined partitioned boxes (prevents thread deformation, scratch damage, and mixing of sizes).
• Shipping Options:
  • Express Delivery (DHL/FedEx): 3–5 business days for prototype or small-quantity orders.
  • Air Freight: 7–10 business days for medium-batch production runs.
  • Sea Freight: 20–25 business days for large-volume bulk orders.All shipments include full tracking and damage insurance.

· Frequently Asked Questions (FAQ)

• MOQ (Minimum Order Quantity): 500 pieces for standard configurations; 200 pieces for custom designs (with valid technical drawings).
• Lead Time: Standard lead time is 7–10 working days (includes CNC machining and passivation); expedited production (5–7 working days) is available for urgent orders (additional fees apply).
• Customization Capability: Full customization is supported—adjust thread sizes (Metric/Imperial), hex base dimensions, or switch to 316 stainless steel for extreme corrosion environments. Our engineering team validates designs for pressure rating and thread fit.
