Ham-let 3600068 Compression Tube Front Ferrule

Product Description

The HAM-LET 3600068 is a brass front ferrule designed for use in compression tube fittings. It serves as the primary sealing component in a two-ferrule compression fitting assembly, biting into the outer diameter of the tube when the fitting nut is tightened to create a leak-tight mechanical connection. Manufactured from brass and conforming to ASTM B68 and ASTM B75 standards, this ferrule is suited for instrumentation, fluid handling, and process tubing applications where a reliable, repeatable tube connection is required. Licensed plumbers, pipefitters, and instrumentation technicians are the typical installers.

This front ferrule is used in compression fitting assemblies on tubing systems found in commercial and industrial settings. It is compatible with standard two-ferrule compression fitting bodies and back ferrules that accept tube OD connections. Typical applications include process instrumentation lines, pneumatic control tubing, and hydraulic or fluid transfer systems where vibration resistance and leak integrity are critical. Rated for a minimum temperature of -20 degrees C and a maximum temperature of 37 degrees C.

Key Features

• Brass construction conforming to ASTM B68 and ASTM B75 material standards
• Front ferrule design for two-ferrule compression fitting systems
• Tube OD end connection for direct tube bite and seal
• Rated operating range from -20 degrees C to 37 degrees C
• Cross-reference to Swagelok part number B-813-1

Compatibility

Designed as an OEM-style replacement front ferrule for standard two-ferrule compression tube fitting assemblies using tube OD connections. Cross-references to Swagelok part number B-813-1 per supplier data.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or instrumentation technicians in accordance with applicable piping codes. Before assembly, ensure the tubing end is cut square, deburred, and clean. Do not over-torque the fitting nut, as this can deform the ferrule and compromise the seal. Once a ferrule has been swaged onto a tube, it should not be reused on a new fitting body.
