Ham-let 3600020 Compression Front Ferrule Brass 6mm

Product Description

The HAM-LET 3600020 is a brass front ferrule designed for use in compression tube fittings with a 6mm outside diameter tube. Front ferrules are the primary sealing component in two-ferrule compression assemblies, biting into the tube wall as the fitting nut is tightened to form a leak-tight mechanical seal. This ferrule is manufactured from brass conforming to ASTM B68 and ASTM B75 standards, making it appropriate for use in fluid and gas handling systems operating within a defined temperature range. Installation is performed by licensed plumbers, pipefitters, and instrumentation technicians working on tubing systems in industrial, HVAC, and process applications.

This front ferrule is suited for use in compression fitting assemblies on 6mm OD tubing. It is commonly installed in instrumentation lines, pneumatic control circuits, hydraulic systems, and fluid distribution manifolds where a secure, vibration-resistant tube connection is required. The brass construction makes it appropriate for use with compatible tubing materials in both residential and light commercial or industrial settings. The Swagelok equivalent part number is B-6M3-1, which may assist in cross-referencing for replacement or retrofit applications.

Compatibility

Designed for use in two-ferrule compression tube fitting assemblies accepting 6mm OD tubing. Cross-references to Swagelok part number B-6M3-1 for replacement and retrofit use.

Installation Notes

Installation is performed by qualified plumbers, pipefitters, or instrumentation technicians. Before servicing any compression fitting, isolate and depressurize the line and verify the system is at zero pressure before disassembly. Front ferrules are not typically reusable once fully swaged onto tubing - inspect the tube end and ferrule seat condition before reassembly. Follow the fitting manufacturer's assembly procedure, including the recommended number of turns past finger-tight, to achieve a proper seal without over-tightening.
