Value Collection SS-RF-FT12 Compression Back Ferrule 3/4 in

Product Description

The VALUE COLLECTION SS-RF-FT12 is a stainless steel compression tube back ferrule designed for use with 3/4 inch outside diameter tubing. Back ferrules are the rear sealing component in two-ferrule compression fittings, working in tandem with a front ferrule to create a leak-tight mechanical connection when the fitting nut is tightened. This ferrule is machined from 316 stainless steel and meets multiple ASTM and DIN material standards, making it suitable for demanding fluid and gas instrumentation systems. It is typically installed by licensed plumbers, pipefitters, or instrumentation technicians working on process, pneumatic, or high-purity tubing runs.

This back ferrule is sized for 3/4 inch tube OD and is compatible with standard two-ferrule compression fitting assemblies used in industrial, commercial, and process instrumentation applications. The 1-20 UNF thread standard and overall length of 0.2902 inches conform to widely used compression fitting geometry. Applications include process piping, pneumatic control lines, hydraulic instrumentation, and chemical distribution systems where a reliable tube seal is required. The Swagelok equivalent part number is SS-1214-1.

• Overall length of 0.2902 inches (7.37 mm) for precise ferrule seat engagement
• 1-20 UNF thread standard for compatibility with standard compression fitting bodies and nuts
• Single-piece back ferrule design provides reliable rear tube grip in two-ferrule assemblies
• UNSPSC Code 27121700 and Product Service Code 4720 for procurement and cataloging

Compatibility

Designed as an OEM-style replacement back ferrule for standard two-ferrule compression tube fittings using 3/4 inch tube OD. Cross-references to Swagelok part number SS-1214-1.

Installation Notes

Installation is performed by qualified pipefitters, plumbers, or instrumentation technicians. Before servicing any compression fitting, depressurize and isolate the line completely. Back ferrules must be installed in the correct orientation within the fitting body — reversing front and back ferrules will result in a failed seal. Follow the fitting manufacturer's assembly instructions for proper nut turn from finger-tight to avoid over-swaging the ferrule.
