Value Collection SS-FF-FT4 Front Ferrule 1/4 in Od 316 Ss

Product Description

The VALUE COLLECTION SS-FF-FT4 is a compression tube front ferrule machined from 316 stainless steel for use in tube-to-fitting compression assemblies. This front ferrule seats against the fitting body and deforms around the tube outer diameter during tightening to create a leak-tight mechanical seal. It carries a 1/4 inch tube OD and uses a 9/16-20 UNF thread standard. The overall length is 0.1902 inches (4.83 mm). Plumbers, instrumentation technicians, and industrial pipefitters install this component when assembling or rebuilding two-ferrule compression fittings on stainless steel tubing systems.

This front ferrule is suited for high-purity fluid, gas, and instrumentation tubing applications in residential, commercial, and industrial settings. It is designed for use with 1/4 inch OD stainless steel tubing in systems requiring reliable, vibration-resistant compression connections. The 316 stainless steel construction makes it appropriate for corrosive media, high-pressure instrumentation lines, and sanitary process environments. This part is identified as a functional equivalent to Swagelok part number SS-403-1 and conforms to multiple ASTM and DIN standards applicable to stainless steel tubing fittings.

Key Features

• 316 stainless steel construction meets ASTM A182, A213, A269, A276, A479, DIN EN10122-5, and DIN EN10272 standards
• 1/4 inch tube OD sizing for standard two-ferrule compression fitting assemblies
• 9/16-20 UNF thread standard for precise engagement with compatible fitting bodies
• Overall length of 0.1902 inches provides consistent deformation geometry during make-up
• Functional replacement for Swagelok SS-403-1 front ferrule
• Sold individually, suitable for single-fitting service or rebuild work

Compatibility

Designed as an OEM-style replacement front ferrule for two-ferrule compression fitting systems accepting 1/4 inch tube OD with a 9/16-20 UNF thread standard. Compatible reference: Swagelok part number SS-403-1.

Installation Notes

Installation is performed by qualified pipefitters or instrumentation technicians following standard two-ferrule compression fitting make-up procedures. Depressurize and isolate the tubing system before disassembly. Do not reuse a ferrule that has already been swaged onto tubing, as the deformed geometry will not re-seal reliably. Follow the fitting manufacturer's recommended number of turns past finger-tight to achieve proper ferrule swage without over-tightening.
