    Dry Fit, NO GLUE! Introducing the ultimate solution for connecting 4" corrugated pipe to any 4" smooth wall PVC pipe - our HDPE coupler. Built to last, our coupler is made from the strongest material on the planet, HDPE, which boasts a lifespan of up to 500 years. It has a lifetime guarantee not to crack. Not only is HDPE durable, but it's also flexible enough to withstand underground buried downspouts, which is crucial when the ground settles and shifts over time. Plus, our coupler is effortless to install and requires no PVC glue or cement. Simply connect one end of the coupler to the corrugated pipe, attach the PVC pipe to the other end, and seal it with PVC tile tape - it's that easy. And, because we believe in supporting American-made products, our HDPE coupler is proudly made in the USA. Upgrade your pipe connections with our HDPE coupler and enjoy a durable, long-lasting solution that will stand the test of time. MUST BE DRY FIT. Use PVC Tile Tape for connecting.
