Polylok4" Corrugated Pipe Adapter (4" corrugated to 4" SDR 35 or 4" SCH 40)

Product was delivered efficiently and in a timely manner. Product is big and durable and has a grid lock size compatability.

I’m hopefulOld parts featured next to new Polylok 4” corrugated adapted, new solid corrugated and 3x4 downspout and welded on SDR35 with no fitment issues even though the end wasn’t cut true on the PVC and no room to fix it. This adapter is NOT on the store shelf in the White Mountains of Arizona so I’m thanking God.My Father in law, passed in 21’, added a very nice wood handy capped porch and ramp on the backside of his 2250sf Modular. Drainage was an afterthought and I’m compelled to correct it. TWAS 4” perf corrugated right next to the foundation in 2 places that leaked HABITUALLY…Boooooo

Even my local hardware store after research as not familiar with this fitting had to purchase here. Use PVC tape to attach.

Very nice

Great product - fits onto PVC schedule 40 to irrigation pipe- much cleaner than using tape to connect- professional!

This is a very good fitting for connecting the 4" black corregated piping to either sch. 40 pvc (dwv) piping OR to the 4" thin wall pvc piping. No problems in connecting.

Prior home owner replaced iron sewer pipe - 80+ years old - with corrugated line - UGH!We decided to replace the corrugated in 3 phases, since replacement involves tearing up decking and patio area.But how do you get a good seal between flexible corrugated and smooth PVC?These adapters are the answer!While they might not be 100% water tight for a corrugated transition, we simply wrapped these adapters in tile tape to prevent any sewer leaks.After the Summer is over, phase 2 means tearing up our deck to replace more of the remaining corrugated. These adapters will definitely be part of that repair effort!

I don't understand with the big stors don't sell this. Worked great!

Would be nice if we could find these in the big box stores in Canada

Worked perfectly to go from sewer pipe to Big O
