Hygienic fittings and adapters are specialized components used in industries where cleanliness, sterility, and contamination prevention are critical—such as in food & beverage, pharmaceuticals, dairy, and biotech.
Key Characteristics:
- Smooth, crevice-free surfaces to prevent bacterial growth,
- Easy to disassemble and clean (CIP/SIP compatible)
- Made of stainless steel, typically 304 or 316L,
- Designed to meet sanitary standards like 3-A, ASME BPE, or EHEDG
Common Hygienic Fittings:
- Tri-Clamp (Tri-Clover) - Quick-connect/disconnect clamp-style fitting; the most widely used sanitary fitting.
- DIN fittings - Common in Europe; metric-sized, used in food and dairy
- SMS fittings - Swedish standard; smooth bore, less common than DIN
- IDF/ISO - British standard; similar to DIN but not interchangeable
- Bevel Seat - Threaded and gasketed; often seen in older systems
- I-Line - Heavy-duty with a tapered ferrule; strong and secure for high-pressure systems
