My dad's birthday is coming up in a couple weeks. He has a Kent KT-300 shop vac that I think was manufactured in the 70's. This is one of the best shop vacs I've ever used.

The hose is falling apart and I'm not sure duct tape will suffice much longer. On the tank side, a retainer screw fits into a slot on the hose. See the pictures attached to this post.

What are my options, if any, for replacing the hose? Any suggestions very much appreciated.

They sell generic shop vac hoses by diameter, you should be able to find them at the hardware store. However, you may have to finagle something for the connection to the machine. Seems like a special end piece. You may be able to reuse the original one with a new hose, or jam the end of a new hose into it. Not sure.

If I'm seeing it correctly, the machine-end connector was very cleverly designed. The screw-down pin on the suction outlet would fit into the channel around the hose connector; if it's not screwed down too tightly, just tight enough to hold the hose in place, the hose would have a swivel function -- something very few shop-vacs have.


I agree with others that it would be easy to find replacement hose onto which the original ends can be attached. They probably just screw onto the hose. There might be some glue that might be a bit of a challenge to free up. Try soaking the ends of the hose in a bucket of hot water for a few minutes.


Good luck!

The vacuum end of the hose is just like that on my Tornado vacuum.Best bet-bring the old hose and connectors to a good vac shop-they can make up a new hose for you using the old connectors.I had to do that for my Tornado vacuum.Worked out just fine-cost less than 50 bucks.

Thanks for the suggestions.

As far as replacement hose is concerned, is vacuum hose vacuum hose, or are some types better than others? Reason I ask is that my dad does a lot of woodworking, and I'm pretty sure the old hose is thrashed because of sharp chunks of wood that get vacuumed up. I don't want to inadvertently buy cheap hose and have it destroyed again in short time.

Not yet, but I was headed in the direction of using industrial hose.

Update, I got the ends loose after a couple hours of work (mostly soaking in boiling hot water).

The hose is either 1-1/2" or 1-9/16" in diameter and is reinforced with 16 gauge wire. The wire reinforcement is the only thing holding it together in many places, so I'd like to replace it with the same type of hose. (the gauge of the wire is not critical)

Where can I get 10 feet of this stuff in the next week? Online ordering is fine.

Contact a company in your area that services Janitorial equipment. They can get you hoses and cuffs. If you pay with cash or credit card they will more than likely work with you.

Iíve heard that flex seal works to fix leaks, but Iím not sure how well it works to fix vacuum hose leaks. A new hose might be your best bet, though, as Iíve not read or heard about flex seal and a vacuum hose.
