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

Did not couple. Used duct tape.

It did its job as advertised.

Great for connecting ADS corrugated drain pipe. Easy to connect sections of pipe. Leakproof seal.

It's a coupling, it coupled drain pipe. Did its job.

Works great. Clips easly to the corrugated pipe.

What is there to say? It's a piece of plastic that aligns 4 in flex lines. It does not even really hold them together. It just lines them up - It is likely to leak if you have any pressure. C'est la vie.

Worked well, easily snapped together. Will use more in the future.

Perfect fit, quick free shipping from Home Depot, very happy with the purchase!

Easy to install, but is not tight fitting so it must be sealed. Recommend making your own joint out of twelve inches of pipe, sliced lengthwise and rolled inside both ends. A youtube video is available for this. We will return this product.

Worked like a charm.

Too thin to work properly

I used it for something else.

It was easy to assemble but leaks fairly severely. I ended up cutting an old tube lengthwise to make a coupler and sealed much better.

Works fine but “Extremely expensive” Price increases by the day

It didn’t fit externally or internally. It was the same size

Works great, was able to successfully repair a poked hole in the 6inch corrugated pipe with this
