Do you have a problem where you have 4” SCH40 or 4” SDR35 PVC pipe that you need to connect to corrugated pipe? If Polylok has the best solution for you! Attach one end to the corrugated pipe, and then attach your PVC pipe to the other end, and you’re done. No tools needed other than your own hands. Fits: 4" corrugated pipe to 4" SDR35 pipe or 4" SCH40 pipe

Review: Perfect fit - I needed to run water from a downspout under new pavers that we were putting in for our front steps. This connector was perfect to attach a corrugated pipe to a PVC pipe. The clips worked perfectly to keep the flex pipe attached. I also used flex tape to seal the connection.
Review: Dry Well Connection - Used to completed connection between corrugated pipe and PVC pipe in a dry well. Pricey product but it worked great. Happy I purchased connector.
