Ham-let 3001557 Compression Tube Insert 316 Ss

Product Description

The HAM-LET 3001557 is a compression tube insert fitting made from 316 stainless steel. It is designed to reinforce tubing at compression fittings, preventing tube deformation under compression load. The insert seats inside the tube ID while the compression fitting engages the tube OD, maintaining a secure, leak-resistant joint. With a 0.5000-inch inside diameter and compliance with ASTM A182, ASTM A213, ASTM A269, ASTM A276, ASTM A479, DIN EN10122-5, and DIN EN10272, this insert is suited for demanding fluid and gas handling applications across industrial, HVAC, and instrumentation systems.

This compression tube insert is used in plumbing, instrumentation tubing, and process piping installations where soft or thin-wall tubing requires internal support at the compression fitting joint. Typical applications include compressed air lines, hydraulic instrumentation tubing, and fluid control systems operating within the rated temperature range of -20 degrees F to 37 degrees F. It is installed by licensed plumbers, pipefitters, and instrumentation technicians working on both residential and commercial systems.

Key Features

• 316 stainless steel construction for corrosion resistance in wet and chemical-exposed environments
• Inside diameter of 0.5000 inches for precise fit within compatible tubing
• Tube OD x Tube ID end connections for standard compression fitting assemblies
• Compliant with ASTM A182, ASTM A213, ASTM A269, ASTM A276, ASTM A479, DIN EN10122-5, and DIN EN10272
• Rated for temperatures from -20 degrees F to 37 degrees F

Compatibility

Designed as an OEM-style compression tube insert for use with standard compression fittings on tubing with a 0.5000-inch inside diameter.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or instrumentation technicians. Depressurize and isolate the line completely before disassembling any compression fitting. Ensure the insert is fully seated inside the tube end before engaging the compression nut to prevent fitting failure under pressure. Follow applicable IPC and ASME B31 piping code requirements for the system type being serviced.
