Walker 40000 Universal Universal Exhaust Flex Pipe Flex Tube-Galv.-1" Dia.-25' Lgth.

Reviewing Walker (40000) 1" Diameter - 25' Galvanized Flex Tube.I don't like running my generator exposed to the weather. We occasionally get over 3 feet of snow. We have been without power for a week after a manor winter storm. After seeing "How to extend your generator's exhaust" articles on the internet, I thought I would try this flexible exhaust tube. Earlier reviewers said the tube is coated in oil that smokes the first time you use it. And smoke it does.Photo 1: Tube doesn't blink at 1102 degrees F. It almost glows red.Photo 2: After it cools, the tube turns gun metal blue. Look closely at the tube lying on the asphalt to see the smoke from the oil burning off. The smoke is not exhaust, but hot oil. Keep a fire extinguisher handy.Photo 3: Generator exhaust at end of 25 feet.I ran the generator for only 15 minutes for this test. At over 1000 degrees, the hot tubing could have easily started a house or forest fire.Some people have suggested using silicone tubing which decomposes at about 500 degrees into possibly toxic and flammable byproducts. Good luck with that.This is professional grade exhaust tubing that performs well and withstands hot exhaust.

Works great for getting exhaust fumes away from portable generators. 1 inch threaded Steel pipe fits perfectly to the inside diameter.

Worked fine to get rid of my gophers. Cut 8 feet off, connected to mower's exhaust.Then find gopher's tunnel, put hose in tunnel, cover with dirt, then run mower for about 5 minutes.Next day no more gopher.Fits 3/4 in pipe perfectly. Most small engine exhaust is 1/2 in pipe, need adapter to 3/4 inch pipe.I have enough left over hose for the neighbors.

These have a protective coat of oil that have to be burned off - so allow for at least half an hour of smoke time as it does so, where you have it outdoors or door-open with a fan.The tube is FAR HEAVIER DUTY than the original diesel heater exhaust, and the diameter is a true inch - which is slightly larger. Fortunately the original pipe can be tapped or turned into it.So to install, CUT YOUR ORIGINAL IN HALF. Tap those into each end of your cut to length of the new pipe. There is plenty of length and it is tight enough to make this a leak-proof connection - which you can verify with just a blow test. Your muffler will then slip over the end, and the original pipe will bend tight enough to make the turn into the exhaust port without issue.

I use this hose to get the generator fumes from my RV generator out of the garage when I exercise the generator. It works fine but, because must of it is outside, it rusted immediately after thr first rain. Not just where the heat source is at the exhaust pipe, but the entire pipe rusted. It still works but I'm sure I'll get exhaust leaks eventually.

Very well made, sturdy. Clamp that order page recommends does not shrink down far enough on my generator exhaust. I made a "shim" out of stainless hose clamp and it works great. Bends to 11" radius. 1.125 OD. 1.0 ID.

The product is okay but the listing is misleading. It is definitely not stainless steel as mentioned in the listing, as it completely flunks the magnet test. It may have some stainless steel, but certainly not enough to call it stainless steel nor, to keep it from rusting. But for the price it's not too bad. In addition they have the dimensions listed as 26x2x2 inches. That's about the size of the box it comes in. If you are wondering how long it is, it's about 22 feet long and is 1" inside diameter. Watch out for the ends they are very sharp.

The item was a perfect fit for my small generator exhaust!!

Bon produit, bon prix

Everything was intact and in good condition, measured right on 1" ID perfect!

fits Honda EU3000i.

Ad states pipe is stainless. It is not stainless, it is galvanized.

It burns off galvanized coating if used as exhaust. Great way to die.
