Ham-let 3600056 Compression Tube Back Ferrule Brass

Product Description

The HAM-LET 3600056 is a brass compression tube back ferrule designed for use in compression-style tube fittings. The back ferrule works in tandem with the front ferrule and fitting body to create a secure, leak-resistant seal when the fitting nut is tightened onto the tube outside diameter. Manufactured from brass to ASTM B68 and ASTM B75 standards, this ferrule is suited for instrumentation, process, and fluid-handling line connections where reliable compression sealing is required. Licensed plumbers, pipefitters, and instrumentation technicians typically handle installation of components like this in both industrial and commercial environments.

This back ferrule is appropriate for tube OD compression connections in low-pressure fluid and gas service within its rated temperature range. It is commonly used in instrumentation tubing runs, hydraulic lines, and process piping assemblies where brass compression fittings are specified. The part is sold individually but must be ordered in multiples of 5 per manufacturer minimum order quantity.

Key Features

• Brass construction meeting ASTM B68 and ASTM B75 material standards
• Back ferrule design mates with front ferrule and fitting body for a two-ferrule compression seal
• Tube OD end connection for use with standard compression tube fittings
• Rated for service from -20 degrees C to 37 degrees C
• Cross-reference to Swagelok part number B-814-1 for replacement reference

Compatibility

Cross-references to Swagelok part number B-814-1. Designed as a back ferrule component for tube OD compression fittings. Verify tube outside diameter and fitting series compatibility before installation.

Installation Notes

Installation is typically performed by licensed pipefitters or instrumentation technicians. Depressurize and isolate the line completely before disassembling any compression fitting. Do not reuse ferrules that have already been swaged onto tubing, as the deformed ferrule will not seal reliably in a new fitting body. Follow the fitting manufacturer's assembly instructions for proper nut-turn method to avoid over- or under-tightening.
