## Customer Reviews

### ⭐⭐⭐⭐⭐ Using to attach pvc to orangeburg that is no longer round.
*by P***8 on October 4, 2022*

Very heavy rubber coupling that will conform to old pipe that's no longer round, has high quality stainless clamps. This will work until I replace all the 4" to my septic.

### ⭐⭐⭐⭐⭐ Value
*by K***N on September 22, 2022*

Used these to connect central duets collection pies in woodsho. Heavy duty and cheaper than I could purchase at local hardware store. Great value and arrived expediently.

### ⭐⭐⭐⭐⭐ Not for dust collection
*by A***N on March 27, 2024*

I don’t feel it’s fair to give this product less than five stars, because it appears sturdy and as advertised, but it doesn’t meet my needs at all. I bought this to connect four-inch pvc (sewer) pipes and gates for a wood shop sawdust collection system, but these couplings are so oversized as to be unusable for this purpose. I can’t tighten them enough to form a proper seal; they bulge and deform too much.
