3Inch Flexible Ducting Hose 16.5 feet Black Aluminum Ducting Dryer Vent Hose with 2 Screw Clamps for Heating Ventilation Air Conditioning (HVAC), Boat Blower, Exhaust Grow Tents

I got a laser cutting machine which has a 3-inch hose connector. It came with a short hose and I needed a longer one, but in my country I could only find 4-inch hoses. I decided to pick this one up and I'm very pleased with it, as it fits on the 3-inch host connector in my laser machine very well. It is also well made, unlike traditional dryer hoses which have a very thin layer of material around the actual string that makes the hose, which tend to tear by the tension of the inner string.

I don’t know what those other guys are talking about. I bought this for my diesel heater. Stinks like crazy actually made me sick to my stomach. Sending it back do not recommend

quality product

Used this as ducting from a diesel heater to a rooftop tent, it definitely serves the purpose, outside of the tube doesn’t get too hot to melt anything and the air coming through stays at a warm temperature (depending on how long of a run you’re pushing it) only negative thing is the plastic outer liner is prone to peeling at both ends of the tube.

I was looking for a good quality hose for my diesel heater and this one is great. Fits perfect, keep heat in, & easy to pack.
