Pipe Expander MAR-POL M55650 for 29–89 mm Pipes

MAR-POL M55650 pipe expander for 29–89 mm pipes is a compact accessory designed to expand and shape metal or plastic tubing. The accessory fits applications where a controlled, uniform increase in pipe diameter is needed for joining, flaring or fitting connections. It is intended for use with compatible power tool drives or manual fixtures that accept this type of expanders, offering on-site adjustability for plumbing, HVAC and general repair tasks.

Advantages

The pipe expander provides a stable, concentric expansion across the specified diameter range, reducing the likelihood of uneven flares or deformations. Its compact design allows use in confined spaces and on-site adjustments without the need to replace or buy multiple fixed-size tools. The tool accessory is suitable for both metal and plastic pipes within the stated size range, enabling a single accessory to cover common plumbing and HVAC tube sizes.

Suitable for

• Expanding copper, aluminum or plastic pipes with diameters from 29 mm to 89 mm
• On-site plumbing installation and repair work
• HVAC tubing fitting, shaping and flare preparation
• General maintenance tasks where a uniform pipe widening is required

When it may not be suitable

This expander is not suitable for pipes outside the 29–89 mm range or for applications that require precision machining beyond simple expansion and shaping. It should not be used on brittle or heavily corroded pipes where expansion could cause cracking or further damage. Compatibility with the drive system must be confirmed before use; the accessory does not include a power drive or adapter.

Key specifications

• Applicable pipe diameter range: 29–89 mm
• Intended materials: metal (e.g., copper, aluminum) and suitable plastics
• Design: compact accessory for on-site expansion and shaping
• Typical applications: plumbing, HVAC, repair and maintenance

How to use

Install the expander into a compatible drive or fixture according to the drive manufacturer's instructions. Secure the pipe in a stable position and advance the expander slowly to achieve the required diameter increase, checking progress frequently to avoid over-expansion. Use steady, even pressure and rotate or reposition the tool as needed to maintain concentric shaping. After reaching the desired diameter, retract the expander and inspect the pipe for uniformity and integrity before completing the joint or connection.

What to consider before purchase

• Ensure your drive or tool is compatible with this type of pipe expander
• Verify the pipe material and condition are suitable for mechanical expansion
• Confirm the required diameter range falls within 29–89 mm
• Consider whether additional adapters or fixtures are needed for your setup

Usage recommendations

For best results, use steady, controlled advancement and inspect the pipe frequently during expansion. Test the expander on a scrap section of pipe when possible to confirm settings and compatibility, and follow all safety guidance for the driving tool and personal protective equipment.
