clamp ferrule 3A, 316L Stainless Steel
Key Features & Benefits of Our Sanitary Ferrules
Hygienic Design: Features a perfectly radiused interior corner (ID bore) and a smooth, polished surface finish (Ra ≤ 0.8µm) that eliminates areas for bacterial entrapment and allows for efficient cleaning.
Seamless Integration: Designed to be welded to tubing, our butt weld ferrules create a permanent, smooth internal surface that maintains product integrity and flow.
Quick Disassembly: The grooved end is designed to work with a tri-clamp and gasket, allowing for tool-free disconnection in seconds for maintenance, inspection, or process changeover.
Material Excellence: Manufactured from ASTM A270 compliant AISI 316L or 304 stainless steel for superior corrosion resistance and durability against harsh cleaning agents.
Global Standard Compliance: Manufactured to ISO 2852 and 3-A Sanitary Standards dimensions, ensuring compatibility with equipment and fittings from suppliers worldwide.
Types & Configurations
Butt Weld Ends: The most common type, where the ferrule is welded directly onto the pipe for a permanent, flush connection.
Threaded Ends: Less common in sanitary applications, but available for connecting to threaded pipe.
One End vs. Two Ends: Available as a single ferrule for one end of a pipe, or as a union with a ferrule on both ends for connecting two pieces of tubing.

Industries and Applications
Our ferrules are indispensable for creating sterile connections in:
Food & Beverage: Pasteurizers, mixers, tanks, and filling lines where frequent cleaning is required.
Pharmaceutical & Biotech: Fermenters, bioreactors, purification systems, and water-for-injection (WFI) lines.
Dairy Industry: Processing lines for milk, cheese, yogurt, and ice cream.
Cosmetics: Manufacturing lines for creams, lotions, and other personal care products.
Frequently Asked Questions (FAQ)
Q: What is the difference between a Ferrule and a Tri-Clamp?
A: The Ferrule is the fitting that is welded onto the pipe. The Tri-Clamp (or Tri-Clover Clamp) is the three-piece metal clamp that fits over the ferrules and a gasket to hold them together and create a seal. They are two separate parts that work together.
Q: Can I mix and match ferrules from different manufacturers?
A: If all ferrules are manufactured to ISO 2852 standards, they should be compatible. However, for a perfect seal and to avoid potential issues, we recommend using ferrules and clamps from the same manufacturer whenever possible.
Q: Why is the internal surface finish so important?
A: A smooth, electropolished finish (Ra ≤ 0.8µm) is critical for preventing microbes from adhering to the surface and for allowing cleaning and sterilizing agents to flow effectively without leaving residue, which is a requirement for CIP/SIP processes.
