· Product Overview

· Core Specifications

Material & Process Standards

• Raw Material: 304 Stainless Steel (general industrial grade) or 316 Stainless Steel (corrosion-resistant grade), offering excellent tensile strength, machinability, and resistance to harsh chemicals and saltwater.
• Processing Technology: Precision CNC turning, threading, and slotting for one-piece forming, ensuring uniform thread pitch and concentricity.
• Precision Tolerance: ±0.01mm for critical dimensions, ensuring a secure, leak-free fit with tubing and mating components; thread tolerance class 6H.
• Surface Finish: Precision milled (Ra ≤ 1.6μm), with optional passivation or electropolishing for enhanced corrosion resistance.
• Structural Features: Multi-step cylindrical body, internal threaded port, push-fit tubing end, hexagonal wrench flat, and installation slot for secure mounting.
• Quality Certification: ISO 9001 certified, with full dimensional inspection via CMM (Coordinate Measuring Machine) and pressure testing for leak integrity.

· Application Scenarios

• Industrial Automation: Pneumatic system connections, fluid transfer lines, and sensor fittings.
• Fluid Handling Equipment: Hydraulic/pneumatic system valves, fluid transfer ports, and pressure control fittings.
• Medical Devices: Diagnostic equipment fluid ports, laboratory sample handling systems, and portable medical instrument connections (biocompatible materials available).
• Marine & Offshore: Subsea equipment fittings, corrosion-resistant fluid transfer adapters, and offshore platform actuation components.
• Aerospace: Lightweight fluid system connectors, UAV pneumatic components, and aircraft system fittings.

· Production Process Introduction

1. Raw Material Preparation: Cut 304/316 stainless steel bars to the required length.
2. CNC Rough Turning: Remove excess material to form the basic multi-step profile of the adapter.
3. Precision Finishing: Turn the hexagonal wrench flat, push-fit end, and internal threaded port to tight tolerances.
4. Slot Machining: Create the installation slot for secure mounting and alignment.
5. Deburring & Polishing: Remove all sharp edges and burrs, and polish critical surfaces to ensure smooth operation.
6. Surface Treatment (Optional): Apply passivation or electropolishing for enhanced corrosion resistance.
7. Quality Inspection: Use CMM to verify dimensions, thread fit, and concentricity; perform pressure testing to ensure leak-free performance.
8. Cleaning & Packaging: Ultrasonically clean the adapter to remove machining debris, then package for shipment.

· Packaging and Shipping Methods

Packaging

• Individual Adapter: Wrapped in anti-static PE bags and protected with foam padding to prevent scratches and deformation.
• Bulk Orders: Packed in foam-lined partitioned cartons to avoid friction and damage between parts.
• Outer Packaging: Export-grade moisture-proof and shock-proof corrugated boxes, suitable for long-distance international transportation.

Shipping Methods

• Express Delivery (DHL/FedEx/UPS): 3–7 working days for samples, prototypes, and small-batch urgent orders.
• Air Freight: 7–15 working days for medium-batch production runs.
• Sea Freight: 20–35 working days for large-volume bulk orders.
• All shipments include real-time tracking and reinforced packaging for precision components.
