Component Specifications

Definition
A ferrule is a precision-engineered ring or sleeve, typically used in sanitary fittings to connect tubing sections securely. It functions by compressing against the tubing when tightened with a nut, forming a tight seal that prevents leaks and contamination. In sanitary applications, ferrules are designed with smooth, crevice-free surfaces to meet hygiene standards and facilitate easy cleaning.
Working Principle
The ferrule works on the principle of compression sealing. When a nut is tightened over the ferrule and tubing, the ferrule deforms slightly, gripping the tubing tightly and creating a metal-to-metal seal against the fitting body. This compression ensures a secure, leak-proof connection that maintains integrity under pressure and temperature variations.
Materials
Stainless steel (AISI 304, 316L), brass, or plastic (e.g., PTFE) for specific applications. Sanitary ferrules are predominantly 316L stainless steel for corrosion resistance and hygiene.
Technical Parameters
  • Size Range 1/4" to 4" (6mm to 100mm)
  • Surface Finish Ra ≤ 0.8 μm (32 μin) for sanitary applications
  • Connection Type Tri-clamp, bevel seat, or face seal
  • Pressure Rating Up to 150 psi (10.3 bar)
  • Temperature Range -40°F to 400°F (-40°C to 204°C)
Standards
ISO 2852, DIN 11851, 3-A Sanitary Standards

Frequently Asked Questions

What is the difference between a ferrule and a fitting?

A ferrule is a component within a fitting assembly. The fitting includes the ferrule, nut, and body; the ferrule specifically provides the sealing action by compressing against the tubing.

Why are sanitary ferrules made of 316L stainless steel?

316L stainless steel offers superior corrosion resistance, especially against chlorides and acids, and is non-porous, making it ideal for hygienic applications where cleanliness and durability are critical.
