Step 7: Flexible rubber coupling with hose clamps
I’m using a 3” to 2” coupling as 3” is the rough diameter of the blower valve and 2” is the size of my PVC pipe. The flexible rubber is lovely since where the leaf blower nozzle on my leaf blower wasn’t a circle but instead a long oval, almost a rounded rectangle.
The Flexible Rubber Coupling fits around where the blower nozzle was previously was and the hose clamps allow for the oddly shaped nozzle to have a custom, leak free fit. The 2” end fits perfectly, as it should, to the standard PVC pipe. You would never know that this wasn’t the original intent for this part.
The leaf blower connects to the 2” PVC pipe via the Flexible Rubber Coupling with Hose Clamps which you tighten by tightening the screws. The connect PVC pipe fits under or through the compost bin wall, and now connect the remaining pipe system.
Finish by capping off all open pipes.
