Dry Fit, NO GLUE!

The best connection to connect 4″ corrugated pipe to any 4″ smooth wall PVC pipe.  This coupler is made out of HDPE – the strongest material on the planet. HDPE lasts 200 to 500 years, yet it is flexible enough for underground buried downspouts which is crucial when the ground settles and you have shifting.

Installation is easy and requires no PVC glue or cement. Attach one end to the corrugated pipe, attach your PVC pipe to the other end and seal with PVC tile tape. It’s that simple. Made in the USA.

MUST BE DRY FIT. Use PVC Tile Tape for connecting.
