MASC – Special flaring tool for rainwater downpipes

Precise fit for every pipe connection – professional quality for roofers & sheet metal workers

As a roofing professional, one thing matters most: connections have to fit. With rainwater downpipes in particular, pipes from different manufacturers often have slightly different diameters. This can make installation at the gutter unnecessarily difficult – or, in the worst case, lead to leaks. That’s exactly what the MASC special flaring tool for rainwater downpipes is designed for: Adjust pipe ends precisely without damaging the material – quickly, in a controlled way, and cleanly.

Specialist use in roof drainage

The flaring tool is used to precisely flare or expand the end of a rainwater downpipe so the next pipe section can be inserted cleanly. It’s especially useful when compensating for tolerances of 1–2 mm, making repairs to existing systems, or combining different systems. You work in a controlled way and achieve an even expansion – for a tight, stable push-fit connection in everyday sheet metal and roofing work. Combined with the right roofing tools and sheet metal tools, installation becomes much more efficient.

Practical tip: prepare it properly
