    1 Answer
    Answer This Question

    A:  Hello, Thank you for your interest in our products. For a permanent underground solution, we would suggest the use of our Strong Back Couplings that feature a steel band to help resist sheer forces. (1056-44RC)

      Answer This Question

      A:  Hello, Thank you for your interest in our products. Unfortunately, this coupling is not meant to plug holes only butt up pipe for sewer drain waste. We would recommend the FPW3132CS fiberglass power wrap to plug that size of hole.

          Great for radon fan install
          Put a pair of these in to install a radon fan into a passive radon system. Fit the 3 inch pipe and 4 inch fan fittings perfectly. Easy to slide on the pipes and the clamps hold firmly.

          This saved me so much time. The prior plumber/homebuilder did not have the main sewer line in line with the hole in the side of the foundation. Using this saved me from chipping away at the concrete to get the pipes to line up. It was easy to install and tighten down. I was able to get it so that it does not leak. Highly recommend.

          These rubber couplings fit perfectly and do and excellent job. To replace all existing drain lines to the nearest point to make glued joints would have taken many hours and grater expense. For under $10 I saved hundreds and have a joint I can trust and depend on.

          Innacurate Description
          Its clealry marked as 4”. It is very much 5”. Luckily I live close to store but still a huge annoyance and waste of my time. I don’t often need parts like this. Is this some sort of twisted “normal” industry standard of measurement? Like a 2x4 NOT actually being 2x4?

            These worked exactly the way I needed them to. I was worried that they’d be too tight when I slid them on so that I’d have a rough time of it, but they were just slightly larger and slid onto my old drain pipe without much effort. Highly recommended. Sure beats smelly glue and primer!

            I have a 42" flagpole and I used this item to cushion the pole in its' mounting bracket. The straps were useful to hold it in place whilst I tightened down the bracket.
