Operating Conditions
Pressure-temperature rating for sanitary ferrules.
Ferrule wall matches tubing wall (1.65 mm standard). Pressure rating same as connected tubing.
Service Conditions
- Working pressure: 16 bar at ambient
- Test pressure: 24 bar (1.5× working)
- Burst pressure: > 60 bar
- Temperature range: –196°C to +400°C
- Steam SIP: +135°C compatible
- Surface finish: Ra ≤ 0.8 μm (EP option)
Actual ratings depend on size, material and operating conditions. Confirm via RFQ for project-specific requirements.

Common Questions
Frequently asked questions about sanitary ferrules.
Engineering and procurement questions we hear most often. For project-specific guidance, send your application details via RFQ.
What surface finish should I specify?
For general sanitary service, Ra ≤ 0.8 μm (32 μin) mill-polished is standard. For pharmaceutical and biotech applications, electropolished (EP) with Ra ≤ 0.38 μm is required per ASME BPE SF4.
For ultra-high-purity (WFI, vaccine production), specify SF5 (Ra ≤ 0.25 μm mirror finish). Surface roughness reports with profilometer measurements available on request.
What is the difference between 304 and 316L?
316L contains 2-3% molybdenum giving superior corrosion resistance, especially against chlorides. For dairy CIP (containing caustic), 316L is highly recommended.
304 is acceptable for utility, water and air applications. For all product-contact surfaces in food, dairy, pharma and biotech, 316L is the standard.
Can these be supplied with electropolish?
Yes, electropolished (EP) finish is available with Ra ≤ 0.38 μm (SF4) or ≤ 0.25 μm (SF5). Includes passivation per ASTM A967.
EP recommended for pharma/biotech, WFI systems, and aggressive chemical service. Adds ~2-3 weeks lead time. Surface roughness report included.
What documentation is provided?
Standard: EN 10204 3.1 MTR with heat number traceability for all parts.
Optional: surface roughness report, passivation certificate, dimensional inspection, full BPE package for pharmaceutical applications.
What is the typical lead time?
Standard configurations in 304/316L typically ship in 1-2 weeks from stock. Custom finishes or specifications: 3-6 weeks.
For project quantities, scheduled deliveries available. Provide target quantity and dates with RFQ for accurate lead time.
How are these connected to tubing?
Tri-clamp connections use a ferrule on each side with gasket and clamp ring. Weld connections are butt-welded to tubing — orbital welding recommended for hygienic service.
Specify connection type with your RFQ. Weld ends ship with bevels prepared for orbital welding. Mixed configurations (clamp + weld) available.
Are these compatible with CIP/SIP?
Yes — all sanitary fittings are designed for CIP (cleaning) and SIP (sterilization) cycles. Smooth internal surfaces and no dead-legs prevent product buildup.
For SIP at 121-135°C, ensure gasket material is rated for temperature (PTFE or silicone). EPDM is suitable for CIP only.
