6 x 4 Fernco Coupler

They were exactly what I needed!

Solid company that will make sure your getting what you need

Worked well when I replaced my old fan. This company is great to work with. I used the chat feature to make sure it all would fit and be the correct size. They were wonderful and answered all my concerns

solid coupling, very tight fit

The couplings are quality, but to get them on a 6" fan and 4" SCH 40 PVC pipe, you have to remove the clamps completely. This eats up a bit of time especially if you have to install them more than once. If they are cold, forget about it.. just place them on your dashboard with the defrost on high for a few minutes and they become more malleable.
