Perfect description and quality.
Purchased for attaching my planer to the shop vacuum system. Arrived a day early, awesome! Product was described perfectly. Sealed great. Was true to size. I could not purchase from local stores as they did not carry that size. Price on point compared to local stores if they would have ordered it.

Great Product, Unique Size
I had searched all over for a high quality 5" rubber pipe couplings and was able to find these at Amazon through Pro Plumbing Supply. They were shipped immediately and were actually more robust than described. Very happy with this product.

Not 5" like advertised
This is sold as 5", but it is not. It is 6". I could have gone to home depot or my local plumbing supply house and picked up a 6" fernco coupler for less. I needed a 5" coupler for my dust collection connection on my 20" planner. I ordered this, due to them listing it as 5". One of the hose clamps broke trying to get it tight enough to seal on the 5" planner outlet. You really have to crank them down to get it shrunk down enough. This will be going in the garbage as soon as I can find a 5" rubber coupler. Overall, if I ordered this to use on a 6" pipe, it would work. It feels like a standard rubber coupler. The hose bands are on the cheap side. If given a choice, I would probably just order a rubber coupler from a plumbing supply house.
