Ham-let 3600005 Compression Back Ferrule Brass 6mm

Product Description

The HAM-LET 3600005 is a brass back ferrule designed for use in compression tube fittings. The back ferrule seats behind the front ferrule in a two-ferrule compression assembly, providing the grip and pull-up force that locks the fitting onto the tubing. It is sized for 6mm tube outside diameter and is manufactured from brass to ASTM B68 and ASTM B75 standards, ensuring consistent material quality and dimensional accuracy. This component is used by instrumentation technicians, plumbers, and industrial pipefitters working on compression tube assemblies in fluid and gas handling systems.

This back ferrule is suited for compression fittings used in residential and light commercial fluid systems, instrumentation tubing lines, and general-purpose tube connections where a reliable, leak-free seal is required. It is rated for service between -20 degrees C and 37 degrees C, making it appropriate for ambient and near-ambient temperature applications. The 6mm tube OD sizing is common in metric instrumentation and process tubing configurations.

Key Features

• Brass construction meets ASTM B68 and ASTM B75 material standards
• Designed for 6mm outside diameter tubing in two-ferrule compression assemblies
• Operating temperature range: -20 degrees C to 37 degrees C
• Compatible Swagelok reference part number: B-6M4-1
• Lightweight at 0.01 pounds for easy handling in tight instrumentation spaces

Compatibility

Designed as an OEM-style replacement or direct-fit component for two-ferrule compression tube fitting assemblies using 6mm tube OD. The Swagelok equivalent part number listed in the input is B-6M4-1.

Installation Notes

Installation is performed by instrumentation technicians or licensed plumbers working on compression tube systems. Always depressurize and isolate the tubing line before disassembling or assembling compression fittings. The back ferrule must be oriented correctly behind the front ferrule before the fitting nut is tightened - reversing ferrule order will result in a failed seal. Follow the fitting manufacturer's make-up procedure for turn counts after finger-tight; do not over-torque.
