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: Great product - Well made product and worked great for my application, i wish i found this sooner.
