The product description states that each of the 3 vacuum extension tubes are 17.7 inches long. Applied. I'm not sure if this could be the seller's issue and not the product's, but in any case potential buyers should be aware that the length of the product does not match the description, at least when I ordered it. I have purchased these 17.7" tubes from another seller in the past and on this previous order the tubes that came out were actually 17.7". Aside from the short length (which is a problem for my use), the pipes appear to be good.
