Lennox furnace hose


Looking for the OEM hose that goes to the combustion air inducer. It's orange in color, square on the outside, and round on the inside. I was having trouble with my furnace quitting so a friend looked at it and pulled the orange hose off and a section broke off.

I replaced the flame sensor and used some automotive vacuum hose to replace it, but was still having problems so I put the old hose back on and everything is now working perfectly, with one problem. The hose isn't long enough to sit flush on both ends. It's connected at both ends and seems to be functioning well, I would just feel better if it was long enough to go all of the way on at both ends.

I have tried a couple of other hoses from heating and cooling places, but they are too small and won't go on the metal end of the air inducer. I have no trouble removing and putting the OEM hose back on but I can't seem to find that one anywhere. Any suggestions?

Thanks

The model starts with G50UH and I have the manual, but I can't find a part number anywhere and can't find that hose online. I have been to 3 heating and cooling places with no luck.

Only problem is I don't need a new switch, just the hose.

on a mid/G50 it needs to be high temp silicone hose or the end will melt and keep cracking. try Graingers or Johnstones and ask for it. it is EXPENSIVE like $10/foot.

I don't have a dog, and I don't see that hose at CozyParts. That was one of the first places I looked. If you can find it there, please provide a link to the part.

Thanks for the suggestions guys but I am looking for the OEM hose that was originally on the furnace since I have tried a couple others and have had problems. If anyone is able to find it could you post a direct link to the part instead of just the main web address?

Here's what it looks like.

Yes they do, I just called them.

I guess I should have called in the first place instead of browsing the online catalog. It's much easier to find when you have the part number. I wish they had part numbers listed in the owners manual so this task would be easier.

Thank you for the help!
