These are good, solid, durable Vac hoses. This is my second one - not because my first wore out (it's still as good as new) - but because I neeed to add more convenient dust collection in my shop. This hose, without the screw on connectors, fits firmly into a 2"-1-1/2" PVC reducer to make a great, flexible connection from individual tools to the 2" pipe I used to construct the dust collection in my small shop.
