    Has anybody found a good source for flexible non combustible tubeing? I guess it should be 2 ". Looking for a low cost alternative to stainless steel. (This is Mr beachy who is cheap... compared to Mrs beachy...lol) Thanks!

    I used Flex auto exhaust tubing. Painted it with black stove paint. Found tubing at an auto parts store. 6 ft. was less than $20

    Thanks everyone for the replies! Wooden Head, i did go to my local (non-chain) parts store,but no luck. Guess i should try others....did you get this at a national chain store like auto zone ect? I would prefer to get this at a landed store. Ordering stuff online can be a pain. Actually like to look the product over before buying. Thanks, Mr Beachy

    I got the 2 inch galvanized steel from McmasterCarr last year and have had no problems, needed 5 feet so the standard OAK kit you buy wasn't long enough. they are very quick with delivery, I believe I got in the next day with standard shipping. There are many options to choose from.
    http://www.mcmaster.com/#duct-hose/=kyiea4 (Super-Abrasion-Resistant Metal Duct for Chips and Shavings)

    • Ideal for wood chips, metal shavings, corrugated fibers, plastic pellets, and powders; also for air, smoke, and dust
    • Rigid
    • Maximum Temperature: Galvanized Steel: 550° F; Type 304 SS: 1000° F
    • Internal Abrasion Resistance: Excellent
    • Clamps: Use U-bolts

    I'm looking for this tubing as well, and am stuck. I ordered 5262K31 for my Harman Advance. My problem is that my stove is about 3" from the wall, and directly behind the wallboard in front of the OAK inlet on the stove is a wall stud.

    So I need a very flexible, metal tubing. The stuff I got from McMaster was heavy, with a bend radius of 8". Nowhere near as flexible as I will need. I'll need something with around a 2" bend radius to get a tight enough "Z" to get out the back of the stove and around the side of the stud in the wall.

    Make sense?


    I have found some very flexible vent duct products, but nothing in metal. I could work with something close in diameter (my stove spec's a 2 3/8" ID hose), but I do not want to deal with 3" dryer alum duct.

    My other thought was to build an "off set" air box of some kind (I like metal fab, I restore old cars....).


    Any ideas??

    If you got the connections in metal why not bend exaust tubing to your needs and have joints expanded and assemble or cut and weld or combination. If you got saw and a good welder,Thats what I did for my system in stainless. Never worry about my exaust system when made with 14 gauge.

    You can't bend flexible tube in a radius equal to it's diameter. It will always kink. The exhaust tubing idea from Bioburner sounds like the most likely solution. Avoid sharp bend.

    Well, actually you can get real close with some products. McMaster has a "bend and stay" aluminum duct tube that is 3" dia and has a bend radius of 1.8" . Unfortunately 3" is as small as you can get it.

    I am going to see what they have at the Autoparts store. I have steel cutting saws and MIG welders. Might just have to get creative. Pressure is that I can't have my town inspector inspect the install until this is done. I am having to use intake air to reduce the window proximity to vent requirements, not because my set up actually needs it!

    Can you use the 3" and just add a reducing collar to the stove's air intake. I didn't care about looks on my pdvc in the workshop so I just crushed the 3" flexible tube with a band clamp until it was a tight fit on the 2" intake tube. A bit ugly, but the building inspector didn't have a problem with it.

    Maybe look into metal air intake tubing as some is metal from header heater to air filter housing on some older cars and vans.
  14. Let me know if it will help you out in a bind- Send me a PM I make 2" and can get you what you need...
