Customer Reviews for Advanced Drainage Systems 4 in. Singlewall External Snap Coupler

Advanced Drainage Systems 8 in. Singlewall External Snap Coupler - NONE OF THE MEASUREMENTS ON THIS ITEM MATCH THE SPECIFICATIONS. Hopefully the attached pictures will help you.

I ordered 2 of these couplings. Normally when someone ordered and pays a normal price they expect the items to be just that. New. Look at what HD sent me. Perhaps someone in management can explain to their customers why they pawn off returned GARBAGE on their them. Or maybe it’s management’s policy to not care?

Lock up tight, fit like a glove.

It's totally a joke. Here's what I received.

The fitting was really easy to snap and fit into place, and it looks like it will hold up.

Excellent fit,works great

they have changed this product and it DOES NOT MATCH THE PICTURE!! the one you get is smooth and very loose fitting and the little bumps inside coupler are just that-- very little, and they DO NOT HOLD the corrugated pipe-- my contractor said it would leak during a heavy down pour.....DO NOT BUY

Did not work, totally useless, very poorly designed. Had to use duct tape, would not connect to 4” sewer pipe. Junk!

Ordered a coupler for 4” tubing… a 5” coupler is what I received, entirely too big and did not fit at all.

Worked as expected. Rigid and easy to use.

I was trying to use pieces of pipe as shown on the internet... I tore out several and used these connectors... better fit and 10 tines easier...

Ive ordered this part 2X and both times received something different

Product word as described

The product description is an external coupler, however it has the SAME diameter as the pipe over which it should fit. Doesn’t work.

End cap was tight fitting and the snap coupler was loose. Still went together well.

The coupling is actually too big. The 4 in drain pipe doesn't really snap in securely. It just slides in and out. I had to tape the pipe and coupling together.
