3/4-inch hydraulic copper expander head

This 3/4-inch hydraulic copper tube expander head is designed for plumbing professionals and DIY users who need to flare copper pipe quickly. The eccentric cone mechanism creates a smooth, uniform flare face without scratching the material. It fits hydraulic expander tools and weighs 133g for easy handling.

Check tool compatibility and pipe size

Verify that your hydraulic expander accepts a head with a maximum diameter of 45mm and height of 40mm. The head is sized for 3/4-inch standard diameter copper pipe only. Ensure your tool provides the hydraulic pressure required to operate the eccentric cone and automatic rebound function.

Replaces manual flaring tools

This head upgrades from manual flaring tools that require more force and can leave uneven flare surfaces. The automatic cone rebound and re-rotation finish the flare face cleaner and faster. The jump is worth it when you regularly flare 3/4-inch copper pipe and want consistent results with less effort.

Questions about this item

What comes in the box and do I need a separate hydraulic expander tool to use this head?

The package contains one tube expander head only; a compatible hydraulic tube expander is required and not included.

Which size should I choose if I am working with three-quarter-inch copper pipe?

This head is built for 3/4-inch standard diameter copper tube, matching the 45 x 40 mm dimensions listed.

How does the 133 g weight affect handling when the head is mounted on a hydraulic expander?

At 133 g the head adds minimal mass, keeping the assembly light enough for one-handed positioning while the eccentric cone forms a smooth, uniform flare.
