Ham-let 3500040 Front Ferrule 316 Ss 8mm Tube Od

Product Description

The HAM-LET 3500040 is a compression tube front ferrule machined from 316 stainless steel for use in twin-ferrule compression fittings. The front ferrule seats against the fitting body and bites into the tube wall during assembly to create a pressure-tight, leak-free connection. It is designed for an 8mm tube outside diameter and is a single-piece component sold individually. Licensed pipefitters, instrumentation technicians, and process plumbers install this ferrule as part of a standard compression fitting assembly in fluid and gas systems where corrosion resistance and repeatable make-up are required.

This front ferrule is suited for instrumentation tubing, process piping, and pneumatic control line applications where 316 stainless steel is specified for compatibility with corrosive media, high-purity fluids, or demanding temperature and pressure environments. It is commonly installed in industrial, offshore, chemical processing, and laboratory settings. The 8mm tube OD sizing matches metric tubing standards used in European and internationally specified systems. Installation is typically handled by instrumentation or process piping professionals as part of a complete ferrule and fitting assembly.

Key Features

• 316 stainless steel construction for corrosion resistance in aggressive media
• Front ferrule geometry designed for twin-ferrule compression fitting assemblies
• Sized for 8mm tube outside diameter metric tubing
• Single-piece component for individual replacement or assembly builds
• Cross-references to Swagelok part number SS-8M3-1 for compatibility reference

Compatibility

Cross-references to Swagelok part number SS-8M3-1. Designed as an OEM-style front ferrule for use with standard twin-ferrule compression fittings accepting 8mm tube outside diameter.

Installation Notes

Installation should be performed by a qualified instrumentation technician or licensed pipefitter following the fitting manufacturer's make-up procedure. Depressurize and isolate the line before disassembly or assembly. Do not reuse ferrules that have previously been fully swaged, as re-make may not produce a reliable seal. Consult applicable process piping codes such as ASME B31.3 for pressure system requirements.
