This is a good quality hose and it will replace the worn out hose that came with your shop vac but there is something else to consider.  Although this hose will fit into a standard shop vac the accessories that came with your shop vac such as the extension tube, crevice tool, etc. MAY NOT FIT THE OTHER END OF THIS NEW HOSE! only Mr. Nozzles accessories or accessories that use a 1 1/2" I.D. hose end will fit this hose, and Mr. Nozzle does not have alot of accessories to go with this hose so you may end up with a great hose but a poor nozzle etc. at the end of it.
