Excellent Switch

I have a 1981 Reznor ceiling mounted furnace that worked fine until the last year. The air intake proving switch failed because a wasp nest had totally filled the 6" pipe! Taking it apart showed the diaphragm was split. This product, though the photo was not exactly what was shipped (the actual one had nips not fittings on it) worked immediately with a bit of modification with a piece of hose. It works great now. Bye nest, thanks Pex!
