ROTHENBERGER 222403 Eccentric Flaring Tool for 6-18 mm Copper, Aluminum, and Soft Steel Pipes, 45° Single Flares

Produce flawless 45° single flares on tubing from 6 to 18 mm (1/4" to 3/4") with the ROTHENBERGER 222403 eccentric flaring tool. Its self-centering clamping bar and integrated depth stop eliminate guesswork, ensuring uniform, burr-free connections for HVAC, refrigeration, automotive, and plumbing systems.

Overview

The ROTHENBERGER 222403 is a professional-grade manual flaring tool engineered for copper, aluminum, and soft steel tubing. Using an eccentric (tumbling) flaring cone, it produces consistent 45° single flares without cracking or thinning the pipe wall. The robust metal alloy construction withstands daily jobsite use, while the compact design allows one-handed operation in tight spaces.

What stands out

• Eccentric flaring cone rotates and presses simultaneously for smooth, concentric flares.
• Self-centering clamping bar holds tubing securely without marring the surface.
• Integrated depth stop prevents over-tightening and ensures repeatable flare dimensions.
• Accepts an external ratchet drive (not included) for faster operation on larger diameters.
• Lightweight and portable — easily fits in a tool bag or service van.
