Fernco 1056-44W 4-inch Flexible Pipe Coupling Plumbing Plastic PVC ABS, Cast Iron, Lead in White

In an attempt to make my radon mitigation system less unsightly, I ordered these so it would match the white PVC pipes. My local big box store only carries black. So I ordered these more for astatic reasons than anything else. I was able to use this to connect my fan to the PVC pipe. Seems like good quality.

Worked great for my application.

Thank you! I may be ordering another!

So disappointed in its size and black marks that won't come off. This thing is huge for a 4" diameter. ID and OD seem oversized.UPDATE- Even though the outside diameter is larger than most it was a much better fit overall. It still came damaged minus 1 star.

This fit perfectly as a coupling connection on exterior pvc (sump pump discharge lines). The installers didn't compact the dirt and the pvc kept sinking (already been 'fixed' once) so I needed my own solution to remedy the gap/separation growing further apart. I connected two of these (4-inch flexible coupling) and tightened the bands/screws and everything is secure. I did have to cut the plastic along the seam to fit them over the existing pvc, but for the purpose I'm using them for that isn't an issue. I just need the top piece and the bottom piece to 'hold' together and this does the job. Looks more professional too.

Good product with decent clamps but arrived too late to use

This item works great and is as advertised.

Time tested Fernco coupling. For some reason local stores don't know they come in white. Great to finish out a gutter connection and match cleanly.
