0615AA Corrugated Singlewall Pipe Internal Coupler, 6", No Color

Homeowner. I connected up my two gutter pipes with 6 inch corrugated pipe (probably should have gone with 4 inch). Connected them both to PVC Y connector (with their PVC to corrugated pipe connectors), and then connected up two corrugated pipes with this product. Buried it all. It all is working great.
