Ham-let 3500115 Compression Tube Back Ferrule 316 Ss

Product Description

The HAM-LET 3500115 is a compression tube back ferrule designed to create a reliable, leak-tight seal in compression-style tube fittings. The back ferrule works in conjunction with a front ferrule and fitting body to grip and seal tubing under compression load. Machined from 316 stainless steel, this ferrule meets multiple ASTM and DIN material standards, making it suitable for demanding fluid and gas handling applications. It weighs 0.01 pounds and is sold individually. Licensed plumbers, pipefitters, and instrumentation technicians are the primary installers of this type of component.

This back ferrule is used in industrial, commercial, and instrumentation piping systems where tube compression fittings are required. Typical applications include process instrumentation, hydraulic and pneumatic tubing systems, chemical handling lines, and analytical equipment connections. The Tube OD end connection type means the ferrule slides over the outside diameter of the tubing before assembly. The rated temperature range runs from -20 degrees F to 37 degrees F, making it appropriate for ambient and moderately cold service conditions.

Key Features

• 316 stainless steel construction meets ASTM A182, A213, A269, A276, A479, DIN EN10122-5, and DIN EN10272 material standards
• Back ferrule design for use in two-ferrule compression tube fitting assemblies
• Tube OD end connection for direct installation over tubing outside diameter
• Rated temperature range: -20 degrees F minimum to 37 degrees F maximum
• Lightweight at 0.01 pounds for ease of handling during assembly
• Single-piece packaging with a minimum order quantity of one

Compatibility

The Swagelok cross-reference part number SS-304-1 is noted in the supplier data. Beyond that reference, specific compatible fitting bodies or tubing sizes were not stated in the available product data. This ferrule is designed as an OEM-style component for two-ferrule compression tube fitting systems using Tube OD connections.

Installation Notes

Installation is typically performed by licensed pipefitters or instrumentation technicians in accordance with applicable piping codes such as ASME B31.3 for process piping. Before servicing any compression fitting, isolate and depressurize the line completely and verify the system is free of hazardous media. Ensure tubing is cut square, deburred, and cleaned before inserting into the fitting body. Do not reuse ferrules that have already been fully swaged onto tubing, as proper sealing cannot be guaranteed after initial compression.
