Diversitech 278-FS-05 Swaging Adapter 5/16 Inch

Product Description

The DIVERSITECH 278-FS-05 is a 5/16-inch swaging replacement adapter designed for use in refrigerant line and copper tubing service work. Swaging adapters allow a technician to expand the end of one tube to accept another tube of the same diameter, creating a proper joint for brazing or soldering without the need for a separate coupling fitting. This adapter is a direct replacement component for compatible swaging tool sets and is typically handled by licensed HVAC technicians performing field fabrication or repair on refrigerant piping systems.

This adapter is suited for residential and light commercial HVAC applications where copper tubing service is required. It is used during installation, retrofit, or repair work on split systems, package units, and other equipment that uses copper refrigerant lines. The 5/16-inch size addresses a common tubing diameter found in smaller-capacity systems and specific suction and liquid line configurations.

Key Features

• 5/16-inch swaging size for precise tube expansion to matching diameter
• Replacement adapter for swaging tool kits, extending tool service life
• Enables same-size tube joints suitable for brazing or soldering
• Eliminates need for separate coupling fittings in field fabrication
• Compact adapter format for use with standard swaging tool bodies

Compatibility

Designed as a replacement swaging adapter for use with compatible DIVERSITECH swaging tool sets that accept 5/16-inch adapter components. No additional specific model compatibility data was provided in the product information.

Installation Notes

Swaging adapters are installed and used by licensed HVAC technicians during copper tubing fabrication or repair. Before working on any refrigerant system, recover all refrigerant per EPA Section 608 requirements and ensure the system is fully depressurized. Use the adapter only with a compatible swaging tool body and follow the tool manufacturer's operating procedure to avoid splitting or distorting the tubing. Braze or solder the resulting joint per applicable mechanical codes and equipment manufacturer specifications.
