8" Inch / 200 mm Metal Vent Duct Connector - Vent Extension - Galvanized Metal Pipe Connection - 8 Inch Dryer Vent Coupler - Metal Drier Pipe Coupling - Rigid 8In Metal Hose Extension

Inexpensive and good quality. Worked well for fitting a flue cap to my static caravan boiler outlet. A 100mm (4") pipe fits inside. The problem I had was that the outlet pipe on the roof of the caravan was exactly the same diameter are the flue cap supplied we're exactly the same diameter. This solved the issue. Just needed a couple of self-tappers to hole it in place

Ideal length for elongation of my wind turbine

I'm not sure why it works but it does. It's a perfect fit for connecting two 4-inch pipes together. Doesn't matter if one, both or none of sides are crimped. Not sure why the big box stores don't sell this piece. I've looked at many stores and tried different connectors and nothing has worked like this Amazon product does.

Hält, was es verspricht! Wortwörtlich.

This worked to join to dryer vent hoses.

This is an actual 5 star review. My current wall dryer vent outlet was pliable and did not extend far enough out of the wall. I was able to firmly insert the new duct connector within my wall outlet to strengthen and extend it. My dryer hose now has a strong duct to connect to. The duct connector is well made and strong! Hope my review helps others.

Die Muffe fällt deutlich zu groß aus und dichtet dem entsprechend nicht ab, ca. 2-3 mm Spiel.
