Fernco P1056-150 Flexible PVC Pipe Coupling for Cast Iron, Plastic or Steel to Cast Iron, Plastic or Steel Plumbing Connections

Here's a coupler that's well made and doesn't leak. Very pleased overall.

The 1-1/2 inch is a perfect fit on a 1-1/2inch PVC drain pipe. My kitchen drain to the basement isn't on a downward enough slope so it occasionally gets sluggish. We cut the pipe to access it with a snake and hose to flush it through once or twice a year as needed. This works very well for keeping it from leaking and still being able to access it when needed. No glue needed which would have defeated our purpose. It fits snug and did need a little wiggling to put it on. Once the screws on the clamps are tightened it will not budge. We'll see how well it holds up long term, whether the rubber gets hard and cracks etc. Bought a spare since it's not something I could find locally (No big box DIY stores nearby). I can see this being very useful for multiple in a pinch needs.

The coupling was well made . But I oringinally bought the wrong size because I thought the sizes went by O.D, turns out the product size is measured by I.D. Quite a difference so I had to order another coupling which worked very well for my application.

I used this for my sump pump pipes. They were originally hard piped all the way through the lid into the pump pit. This meant when I needed to get access to pit or service the pump I could only lift lid 6 inches unless I cut the pipe apart. Using these allowed me to pull pipe apart quickly and fully access the pit then quickly reattach when finished. Work perfectly.

I needed this to connect a Fein vacuum to a 2 1/2 X 1 1/2 reducer. This was the only rubber coupling I could find that was 1 1/2 inch. When it arrived, the size of 1 1/2 inch was molded into it. I measured and the inside diameter was 1 7/8 inch with an outside diameter of 2 1/8 inch. I tried it anyway. The rubber was flexible enough and the clamp range wide enough that I was able to tighten the clamps so it would seal to my 1 1/2 inch fittings. In short, it didn't look like the right size but it worked. For this reason, 4 stars. A better product description would help.

Wrong size but will make due

There are some that say this type of hose/coupling should not be used on a Hot Tub, but I beg to differ!PVC pipes are hard to align in tight spaces, and even worse, they tend to leak and break if they are handled after installation. After several years of replacing PVC fittings that were damaged every time I removed my Hot Tub Filter, I decided to take an easier route!I Installed this bad boy in between the pump and my filter, and I haven't had any issues since. When I want to change the filter, I simply loosen the clamps, remove the coupling, and then remove the filter. No broken/stripped PVC couplings to deal with!It is very strong as it has held up to the high pressure and chemicals in my Spa for a couple of years now without any issues. Highly recommended, especially if you need a coupler/splice for a Spa or Hot tub.

Well made. Would buy again.
