FerncoP1056-33 3-Inch Stock Coupling

Good quality, decent price. Worked well.

I needed to fix what the “professionals” left behind my wall many years ago. Someone used the wrong type of coupling to go from ABS to copper. This one worked perfectly! No more seepage between the two pipes.

The reason for the 4 stars is that I had to ask for a refund because it came with only one clamp. Obviously it was suppose to have two (just like the pic) and from the looks of the coupling it had one on there at one time because you can still see the imprint that it left. It was not in the box and It was a decent coupling but they didn't send it complete. I could have gone to the big box store for it but It was the convenience of being able to order online. These things happen!

Exactly as expected and high quality. Used to install a Radon mitigation system, these fit perfectly on both sides of my radon fan to connect it to 3" PVC pipes. The radon fan is slightly larger than 3" so to get these on you simply put them in warm water and it makes them just flexible enough to get on the radon fan. This was actually my second radon fan installation using these so all 4 are working perfectly.

Superior product! Really nice thick rubber so soaked it in HOT water for a few minutes before installing (was a tight one handed install). My pipe gap was angled and the two pipes I was joining were rigid and off alignment by 1/4" so I needed the 6" of width to securely fasten to prevent a leak.
