Answer

This coupling is made to fit clay to plastic. You would need the cast iron to PVC series which is a 1056. Contact Fernco Customer Service with your size pipes for a specific part # for this application. This is the intended use of the coupling.

Can these go over a hose barb intended for 1" id hose?

Answers

why not? I use the various sizes to connect anything from PVC pipes to flexible hoses rubber and plastic. I use 1.5" and 2" fernco couplers to connect plumbing lines. I glue everything else with PVC cement including the P and S traps knowing they will never leak. when I need to disconnect the under kitchen sink line for cleaning the trap I simply undo the fernco coupler. I have never known these couplers to leak when installed properly and tightened

I needed this to go from clay to pvc. This was easy to install and was just the correct size to fit over both sides. Also, the pipes weren’t completely in line with each other as they were a few degrees off. This allowed for a slight “bend” in the system at that point. The straps are easy to get tight over the pipes to prevent leaking. Overall, I’m happy with this product.

I use these in my shop for my dust collection system, going from 4 inches is common and what my dust collection system is, going down to the size of my different tools is always the challenge, and before everyone jumps on it, yes I do know there other ways of doing it, this is just my preferred method. I bought this for a project I was doing and ended up not using it, but will hang on to it, because I know there will be a use. Love these and would recommend them to any wood worker.

The 1-1/2 PVC fit perfect. the 3 inch to copper DWV was very loose fitting but did work. It' fortunate that I was able to pass the 1-1/2 beyond the connection of the coupling. Therefore there was no leaks. But,,,,,,,,,, If you need a tight fit to the copper DWV this product might not be the right one for your application. It's obvious I painted the copper white as it is inside a cabinet, hence if appears the color of white PVC.

Perfect for connecting existing sewer line to house with ABS or PVC piping. Note that not all Clay pipe manufacturers are the same outer dimension, so you may have to stretch the coupling a bit and use a lubricant such as soap to slip it onto the Clay pipe. I have done this on two separate installations without any problems what-so-ever.
