Why Metric Tubing Matters in Industrial Applications
Metric tubing (measured in millimeters) is essential for precision-driven industries like aerospace, medical devices, and automotive manufacturing. Unlike imperial tubing, metric dimensions ensure global compatibility and exact tolerances (±0.05mm). Choosing the right supplier impacts:
- System integrity: Leaks/failures from poor-fit tubing cost 10x more than premium materials
- Regulatory compliance: ISO 13485 (medical) and AS9100 (aerospace) demand certified materials
- Production efficiency: On-time delivery prevents assembly line shutdowns
5 Critical Selection Criteria for Suppliers
-
Material Certification
- Demand mill test reports (MTRs) for 316L stainless, titanium, or nickel alloys
- Eagle provides EN 10204 3.1 certificates with every order
-
Tolerance Precision
- Medical/optical applications: ±0.01mm
- General industrial: ±0.1mm
Eagle’s laser-calibrated cold-drawing achieves ±0.03mm consistency
-
Customization Capabilities
- Bespoke cutting, bending, polishing (Ra ≤0.2μm)
- ID/OD surface treatments (passivation, electropolishing)
-
Lead Time Reliability
- Stock tubing: 3-5 business days
- Custom projects: 2-4 weeks (industry average)
-
Traceability
- Full metallurgical history from smelting to delivery

How to Verify Supplier Credibility
-
Request Samples:
- Test tolerances with micrometer calipers
- Check surface finish under 10x magnification
-
Audit Certifications:
- Valid ISO 9001:2015 registration
- Material-specific certs (e.g., ASTM A269)
-
Supply Chain Transparency:
- Confirm raw material origins (Eagle sources EU/Japan mills only)
Real-World Applications
-
Hydraulic Systems:
- 8mm 316L tubing handles 5,000 PSI in excavators
-
IV Drip Systems:

Ordering Checklist
- Specify:
- Material (e.g., 316L, Ti6Al4V)
- Dimensions (OD × WT × length)
- Surface finish (annealed, polished, etc.)
- Validate:
- Tolerance class (ISO 3304)
- Packaging requirements (VCI paper for corrosion-prone areas)
- Confirm:
- Lead time and shipping terms
