We have an old NuTone central vacuum system. Apparently, the company updated the sockets a few years ago, and now the latest hoses do not fit our old model. I'm happy to report that after a little research I found this hose and it fits! It works great and is actually a big update for us. Our old hose didn't have a switch to turn it on and off - it just turned itself on automatically as long as it was connected to the network. This is a nice benefit as I can now leave the hose connected while I answer the phone and need to take a few minutes break. It is very durable. I'm impressed with the quality and this price is a lot cheaper than others I've found on central vacuum sites. I am very happy with my purchase and would recommend this product to anyone if it fits your central vacuum model.
