Good fir
I used already 3 piece,all of them worked perfectly on the pvc 4" sch40 pipe. Nice shield,easy to adjust the tightness and stainless steel. What i don't like about it, I feel little bit thinner the rubber what you can buy in big box store,but yes,is much cheaper. I hope last long term.

Good clamp 60 inch-pound NOT foot-pound
Good couplings for no hub pipes Make sure you torque it to 60 inches-pound NOT foot-pound like some of the reviews that complain about the clamps bad. Realized that after destroying two of them lol and cursed junk. But itโs my brain cell deficiency on this one. If you are installing a lot of these couplings, get some duck butter not just any grease, that things makes slipping these couplings on super easy.

Good product. Works as intended
This coupling is also suitable for a range of pipe types, it felt pretty snug on sdr35 before fastening the clamps. Any gripes are likely user error. (Such as using a torque wrench on the clamp bands)

Great value. High quality
I absolutely love these. Unlike some we use from the supply house, itโs actually easy to start the clamps in the worm gear mechanism. They seem to be high quality and we havenโt had any leaks

not refined
Having used many different clamps of this type, this one is not well made or refined. Given the important of such an item, keeping your drainage system water type and sewer gas free, and often, once completed, the drywall is closed up and painted and you can not monitor its success or slow failure. It arrived beat up and deformed because of poor packaging. Just loose in a bag it has clearly been crushed being at the bottom of a pile. But also the rubber is not well formed. It uses 5/16 nuts to tighten, to a recommended torque of 80 in pounds. Every major maker of these clamps uses 3/8 bands and recommends 80 in pounds, but 60 inch pounds for the smaller versions that do also use 5/16. Something doesn't add up. I would not use this fitting behind a closed wall where it can not be monitored.

Not as good as a fernco!
This thing is very light duty. It is 1/4 of the thickness of a fernco. It is not where near as good as a fernco. Not even remotely close. Do not use this in underground or in closed wall applications! Youโve been warned.
