Sanitary Ferrule (SUS304, Weld)
Model: PSF-03
PSF-03 is a SUS304 ferrule welded onto sanitary piping to form a tri-clamp connection port. With sanitary-piping standard finishing and smooth internal polishing, it is used at the interface between welded piping and clamp-connected lines in pharmaceutical, biotechnology, chemical, food and beverage, and secondary battery processes.

Frequently Asked Questions
- How does a standard ferrule differ from a pipe ferrule?
- A standard ferrule is either a short adapter with tri-clamp flange faces machined on both sides, or a part supplied with a weld neck on one side. The pipe ferrule (PSF-41) has a long weld neck on one side, while this product (PSF-03) has a short weld form that is welded directly to the pipe end. Choose based on line configuration and installation conditions.
- Is there anything to watch out for during welding?
- On hygienic lines, the standard practice is to apply orbital welding under an argon back-purge environment to prevent oxide scale on the inner surface. Immediately after welding, internal cleaning and (where required) passivation are needed to meet the cleanliness requirements of hygienic lines.
- Which is appropriate, SUS304 or SUS316L?
- SUS304 is the standard for most general food, beverage, and hygienic lines. SUS316L is generally selected for lines with high chloride concentrations, lines containing strong organic acids, and GMP-grade pharmaceutical and biotech processes.
- How is the size selected?
- Sanitary ferrules are supplied in tri-clamp standard sizes (1", 1.5", 2", 3", etc.). Tell us the pipe outer diameter and clamp size you are currently using and we will prepare a matching specification.
