Ham-let 3500138 Compression Tube Front Ferrule 316 Ss

Product Description

The HAM-LET 3500138 is a compression tube front ferrule designed for use in high-integrity tube fitting assemblies. The front ferrule is the primary sealing component in a two-ferrule compression fitting, biting into the tube outer diameter to create a leak-free, pressure-tight connection when the fitting nut is torqued. Manufactured from 316 stainless steel meeting ASTM A182, ASTM A213, ASTM A269, ASTM A276, and ASTM A479 standards, this ferrule is built for demanding fluid and gas system applications where corrosion resistance and dimensional consistency are critical.

This front ferrule is suited for use in instrumentation, process piping, pneumatic, and hydraulic tubing systems found in industrial, commercial, and laboratory environments. It connects at the tube outer diameter and is compatible with standard two-ferrule compression fitting bodies and back ferrules of the appropriate tube size. Installation is performed by pipefitters, instrumentation technicians, and mechanical contractors working on compression-style tube fitting systems. The rated operating temperature range spans -20 degrees F to 37 degrees F.

Key Features

• 316 stainless steel construction for corrosion resistance in aggressive media and environments
• Meets ASTM A182, ASTM A213, ASTM A269, ASTM A276, and ASTM A479 material standards
• Also certified to DIN EN10122-5 and DIN EN10272 for international application compliance
• Front ferrule design provides primary tube grip and seal in two-ferrule compression assemblies
• Tube OD end connection for direct, sleeve-free installation onto tube outside diameter
• Swagelok cross-reference part number SS-1013-1 for reference during sourcing and replacement

Compatibility

Designed as a front ferrule replacement for two-ferrule compression tube fitting systems connecting at the tube outer diameter. Cross-references Swagelok part number SS-1013-1. Verify tube OD size and fitting body manufacturer before installation to confirm dimensional fit.

Installation Notes

Installation is performed by qualified instrumentation technicians or pipefitters following the fitting manufacturer's assembly procedure. De-pressurize and isolate the tubing system completely before disassembling or replacing ferrules. Front ferrules are typically not reusable once swaged onto tubing - inspect tube condition and replace the complete ferrule set when reassembling a fitting. Follow applicable industry codes and the fitting manufacturer's torque and pull-up guidelines for proper seating.
