## Description

Fernco P1056-44 Flexible PVC Pipe Coupling for Cast Iron, Plastic or Steel to Cast Iron, Plastic or Steel Connections

Review: Easy - Worked perfectly for connecting 4” ID ABS
Review: Works Perfectly for an Unconventional Use - Have a high efficiency furnace, A/C unit that vents outside using PVC vent pipe. We had some yellow jackets get in the house and the only way they could get to the 2nd floor master bedroom had to be through the ductwork. Just to be sure, I purchased a very tight circular screen but needed a fernco-like device that not only fit over the end of the PVC vent pipe but with an inside diameter that would allow the hard metal circular screen to fit and stay put. This worked absolutely perfectly! I take it off during winter not only because the yellow jackets are no longer active but when running the furnace, the vent not only carries out combustion gases but due to it being high efficiency, water vapor. If I left it in place, the tight screening would accumulate the water, it would freeze, block the exit, and carbon monoxide is not my friend. Anyway, this Fernco worked perfectly for something it was not even intended to do.
