Diversitech 1839023 Expander Head 1-3/8 Inches

Product Description

The DIVERSITECH 1839023 is a 1-3/8 inch expander head designed for use with compatible tube expansion systems. This tool creates a uniform bell end on copper or compatible tubing, allowing for a direct tube-to-tube connection without couplings. HVAC technicians and refrigeration mechanics use expander heads when joining refrigerant lines, ensuring a clean, leak-resistant mechanical joint. The 1839023 fits into a driver handle or expansion tool body and is sized specifically for 1-3/8 inch nominal tubing. It is suited for field service and shop fabrication work where repeatable, consistent tube ends are required.

This expander head is intended for use in HVAC and refrigeration applications where copper tubing connections must be made without solder-fit couplings. It is appropriate for both residential and light commercial system installations and service calls. Technicians working on line sets, evaporator coils, and condenser connections will find this size applicable to larger-diameter refrigerant piping configurations.

Key Features

• 1-3/8 inch sizing for larger-diameter tubing expansion work
• Creates a direct tube-to-tube bell joint without added couplings
• Designed for use with compatible expansion tool handles and driver bodies
• Supports leak-resistant mechanical connections in refrigerant and HVAC line applications
• Suited for field service and installation environments

Compatibility

Designed as a replacement or supplemental expander head for use with compatible tube expansion tool systems sized for 1-3/8 inch tubing applications.

Installation Notes

Expander heads are installed and used by licensed HVAC and refrigeration technicians. Always recover system refrigerant and depressurize the line set before cutting or expanding tubing. Ensure the expander head is fully seated in the driver before applying force to avoid uneven expansion. Follow applicable mechanical codes and refrigerant handling regulations when working on pressurized systems.
