   I got the 1″ to use on my generator. I used a 220-volt welder at 35 amps (lowest setting) and blasted through this if I wasn’t paying very close attention. Granted, I’m only a hobby welder not a professional. Once I connected it to the generator and fired it up, it worked well. What I didn’t expect was how much it smoked once it heated up. I don’t know if it was manufacturing oil burning off or what, but it stared smoking closest to the inlet and worked it’s way down as it heated up. Temperature gun indicated it started smoking when it was around 400F, which is within tolerance. Per the manufacturer’s website:Galvanized – For applications up to 600°F (315°C) <<< this oneAluminized – For applications from 600°F to 1200°F (315°C to 650°C)Stainless Steel – For applications over 1200°F (650°C)Overall I'm happy and will continue to use it. Just plan to let it 'smoke out' when you first use it.

   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.

   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.

   Great Flexible Exhaust Pipe. It does rust in open weather conditions which implies low low grade stainless steel, but it acomplishes it goal as a flexible exhaust pipe. And for the price point (under $50) the rusting is acceptable. I probrably could have sprayed it with some corrosion inhibitor but was not sure if there were any heat compatible corrosion inhibitors available.

   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.

   I purchase this to route a generator exhaust away from occupied buildings. Too many people get sick or die… not from the hurricane or tornado, but from carbon monoxide poisoning by running their generator on their porch or in an attached garage.I had to buy iron pipe plumbing fittings to make it easily detachable from a portable 5KW generator. When in use, I unroll the exhaust into the yard, which puts it about 20 feet from the house. Then turn the flange nut that attaches it to the generator. I moved the original muffler to the yard end using iron pipe fittings.Safe enough.
