Mastercool 70041 Swaging Punch 1/4 Inch Tubing

Product Description

The MASTERCOOL 70041 is a single-size swaging punch designed to swage 1/4-inch copper tubing. Swaging creates an expanded bell end on tubing so that a same-diameter tube can be inserted and soldered or brazed, eliminating the need for a separate coupling fitting. This tool is used during refrigeration and HVAC service work wherever copper line sets or refrigerant circuits require tube-to-tube joints. It is a hand-operated punch intended for use with a compatible swaging block or lever-type swaging tool set. HVAC technicians and refrigeration mechanics reach for this punch when making field repairs or installing new systems.

The 70041 is suited for residential and light commercial HVAC and refrigeration applications where 1/4-inch copper tubing is common, such as refrigerant suction and liquid line work, mini-split line sets, and refrigeration equipment servicing. The single-size design keeps the punch compact and easy to store in a service bag alongside other tube preparation tools.

Key Features

• Swages 1/4-inch copper tubing for soldered or brazed tube-to-tube connections
• Single-size punch keeps the tool simple and purpose-built
• Compact and lightweight at 1 pound for easy transport in a field service kit
• Eliminates the need for a separate coupling when joining same-diameter tubing

Compatibility

Designed for use with 1/4-inch copper tubing in HVAC and refrigeration applications. Confirm compatibility with your existing swaging block or lever swaging tool set before use.

Installation Notes

Swaging work on refrigerant circuits should be performed by an EPA Section 608 certified HVAC technician. Recover all refrigerant and relieve system pressure before cutting or working on any tubing. Ensure the tube end is cut cleanly and deburred before inserting the swaging punch to achieve a proper flare and leak-free joint after brazing or soldering.
