Value Collection SS-RF-FT8 Compression Back Ferrule 1/2 in

Product Description

The VALUE COLLECTION SS-RF-FT8 is a stainless steel compression tube back ferrule designed for use in high-integrity tube fitting assemblies. This back ferrule seats against the front ferrule inside a compression fitting body, creating a leak-tight seal when the fitting nut is tightened. It is sized for 1/2 inch tube outside diameter and conforms to a 3/4-20 UNF thread standard. Fabricated from 316 stainless steel to ASTM A182, ASTM A276, and ASTM A479 standards, among others, it delivers strong corrosion resistance in demanding fluid and gas service environments. Licensed plumbers, pipefitters, and instrumentation technicians are the typical installers.

This back ferrule is suited for residential and commercial applications involving instrument tubing, process piping, and fluid transfer lines where a reliable compression-style connection is required. It is compatible with two-ferrule compression fitting systems that accept a 1/2 inch tube OD. The part carries a Swagelok reference part number of SS-814-1, making it a widely recognized form-factor in instrumentation and process tubing work. It is sold individually and is appropriate for maintenance, repair, and new installation projects.

Compatibility

Designed for two-ferrule compression tube fitting assemblies accepting a 1/2 inch tube OD with a 3/4-20 UNF thread standard. Cross-references to Swagelok part number SS-814-1 for form and fit reference.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or instrumentation technician familiar with compression fitting assembly procedures. Depressurize and isolate the line completely before disassembling any existing fitting. Follow the fitting manufacturer's assembly instructions for ferrule seating and nut turn specifications, as improper tightening can damage the ferrule or tube wall. Do not reuse a ferrule that has already been fully swaged onto tubing.
