Description
**Sanitary Stainless Steel Vacuum Fittings**
*Premium-Grade Aseptic Connection Solutions for Hygienic Applications*
—
Sanitary stainless steel vacuum fittings are precision-engineered components designed for hygienic fluid transfer systems in industries requiring strict cleanliness, such as food & beverage, pharmaceuticals, biotech, and dairy. These fittings ensure leak-free connections under vacuum or low-pressure conditions while meeting global sanitary standards .

1. **Material Excellence**
– Made from 316L/304 stainless steel, offering superior corrosion resistance and durability.
– Electropolished or mechanically polished surfaces (Ra ≤ 0.8 µm) to minimize bacterial adhesion.
2. **Hygienic Design**
– Tri-Clamp (Triple-Clamp) or DIN 11851 connections for quick assembly/disassembly.
– Smooth, crevice-free interiors to prevent product buildup.
3. **Vacuum Compatibility**
– Seamless integration with vacuum pumps and systems, rated for full vacuum (29.9 inHg) to 10 bar.
– High-integrity seals (EPDM, Silicone, or PTFE) for airtight performance.
4. **Temperature & Chemical Resistance**
– Operational range: -40°C to 200°C (-40°F to 392°F).
– Resistant to CIP/SIP processes and harsh cleaning agents.
