Stainless Steel Ferrule Set – 3/8 in. Tube OD, Front and Back Ferrules

The SFS-6 is a 3/8" front and back ferrule set designed for use with compression fittings in sanitary, high-pressure, and critical instrumentation systems. Made from 316 stainless steel, this set delivers secure tube grip and leak-tight sealing even in harsh conditions involving vibration, thermal cycling, or corrosive media.

Built to work with Superlok and Swagelok® style compression fittings, the dual-ferrule design separates tube grip from sealing—ensuring long-term reliability, especially in Clean-in-Place (CIP) and hygienic fluid processing environments.

Whether you’re outfitting OEM skids, gas lines, or water purification systems, the SFS-6 ferrule set provides the structural integrity and corrosion resistance needed for precise, high-integrity fluid control.

Key Benefits

• Seal: Dual-ferrule design separates sealing and gripping for reliable compression
• Strength: Maintains performance under vibration, pressure, and temperature swings
• Compatibility: Works with 3/8" stainless tubing and Swagelok® style fittings
• Material: 316 stainless steel for high-purity and industrial environments
• Reliability: Prevents galling and tube deformation in repeated installations

Typical Applications

• Sanitary stainless steel fitting assemblies
• Clean-in-Place (CIP) instrumentation
• Water purification and lab fluid control systems
• Hydrogen, CNG, and process gas lines
• OEM skids and instrumentation panels
