Value Collection SS-RF-FT4 Back Ferrule 1/4 in Tube Od

Product Description

The VALUE COLLECTION SS-RF-FT4 is a stainless steel compression tube back ferrule designed for use in two-ferrule compression tube fittings. The back ferrule seats behind the front ferrule and drives the front ferrule into the fitting body as the nut is tightened, creating a pressure-tight, leak-free seal on the tube OD. This ferrule is machined from 316 stainless steel and conforms to multiple ASTM and DIN standards. It is sized for a 1/4 inch tube OD and measures 0.1 inches in overall length. Licensed plumbers, pipefitters, and instrumentation technicians install this type of component in process, instrumentation, and pneumatic tubing systems.

This back ferrule is appropriate for residential, commercial, and industrial instrumentation and process piping applications where a reliable, corrosion-resistant tube connection is required. It is used wherever a two-ferrule compression fitting is specified on 1/4 inch OD tubing, including pneumatic control lines, analytical instrument plumbing, and hydraulic sample lines. The Swagelok equivalent part number for this ferrule is SS-404-1, making it a recognized cross-reference in instrumentation and process industries.

Key Features

• 316 stainless steel construction for corrosion resistance in wet, chemical, and outdoor environments
• Sized for 1/4 inch tube OD — fits standard two-ferrule compression fitting assemblies
• 0.1 inch overall length for compact installation in tight spaces
• Meets ASTM A182, A213, A269, A276, A479 and DIN EN10122-5, DIN EN10272 standards
• Cross-references Swagelok part number SS-404-1
• Tube OD end connection — no threading or flaring required on the tube

Compatibility

Designed as a back ferrule replacement for standard two-ferrule compression tube fittings accepting 1/4 inch tube OD. Cross-references Swagelok part number SS-404-1.

Installation Notes

Installation is performed by licensed pipefitters or instrumentation technicians following applicable process piping codes. Depressurize and isolate the line before disassembling any compression fitting. Ensure the tube end is cut square and fully inserted before tightening the fitting nut — the back ferrule must seat correctly behind the front ferrule for a reliable seal. Do not reuse ferrules that show deformation or scoring from previous installations.
