• Key Processes: 5-Axis CNC Turning → Ribbed Barb Forming → Hex Drive Machining → Deburring → Passivation Polishing → CMM Inspection & Pressure Testing
• Standard Parameters:
  • Dimensional Tolerance: ±0.005mm (ensures precise mating with hoses and ports)
  • Surface Finish: Passivated polished (Ra ≤ 0.8μm) for enhanced corrosion resistance and easy cleaning
  • Custom Features: Hexagonal drive head, multi-ribbed hose barb, and precision internal bore for unrestricted fluid flow

· Application Scenarios

• Industrial Automation: Hydraulic/pneumatic system hose connections, conveyor system fluid line adapters, and robotic tool changer fluid ports.
• Food & Beverage Machinery: Processing line fluid transfer fittings, packaging machine hose adapters, and sterile equipment connections (compliant with FDA standards).
• Medical & Laboratory Devices: Diagnostic instrument fluid line connectors, dialysis machine hose fittings, and sample handling system adapters (biocompatible).
• Marine & Offshore Equipment: Boat engine fuel/water line fittings, offshore platform fluid transfer adapters, and corrosion-resistant hydraulic connections.
• Chemical Processing: High-purity fluid transfer fittings, chemical reactor hose adapters, and corrosive waste line connections.

· Production Process Introduction

1. Raw Material Preparation: Cut certified 304/316 stainless steel bars to exact length and diameter for the fitting profile.
2. 5-Axis CNC Turning: Use high-precision CNC lathes to machine the hexagonal head, internal bore, and barb tail in a single setup for maximum concentricity.
3. Ribbed Barb Forming: Create the multi-ribbed hose barb profile to ensure a secure, leak-resistant grip with hoses.
4. Deburring & Polishing: Remove sharp edges from the hex head, barb, and bore, then polish the surface to a smooth finish.
5. Passivation Treatment: Apply a chemical passivation process to enhance corrosion resistance and ensure compliance with food/medical safety standards.
6. Quality Inspection: Perform CMM dimensional scanning, pressure leak testing, and surface roughness analysis to verify compliance with specifications.

· Packaging and Shipping Methods

• Packaging:
  • Individual Fittings: Sealed in sterile, moisture-proof plastic bags and wrapped in anti-scratch foam padding to protect the polished surface and barb profile.
  • Bulk Orders: Packed in foam-lined partitioned boxes (prevents fitting deformation, barb damage, and mixing of sizes/materials).
• Shipping Options:
  • Express Delivery (DHL/FedEx): 3–5 business days for prototype or small-quantity orders, with temperature-controlled shipping available for medical applications.
  • 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 traceability documentation and compliance certificates.

· Frequently Asked Questions (FAQ)

• MOQ (Minimum Order Quantity): 500 pieces for standard configurations; 200 pieces for custom designs (with valid CAD files/technical drawings).
• Lead Time: Standard lead time is 7–12 working days (includes CNC machining, passivation, and pressure testing); expedited production (5–7 days) is available for urgent orders (additional fees apply).
• Customization Capability: Full end-to-end customization is supported—adjust material grade (304/316), fitting dimensions, barb rib count, thread specs (if applicable), or surface finish (electropolishing for enhanced biocompatibility). Our engineering team validates designs for leak resistance, corrosion performance, and fit accuracy.
