Good quality but limited size range
The material and build quality are great, and it fit perfectly for my 4-inch to 3-inch pipe transition. I just wish there were more size options in this flexible coupling style for other projects.

Reliable for home plumbing
I used this coupling to repair a leaking joint between copper and PVC pipes. It’s flexible and provides a solid seal. The only downside is that the rubber might wear faster if exposed to harsh chemicals, but for my use it’s been great.
