1980s Coleman model 4312 Circulating Air furnace

Hi there


This may be a long shot BUT does anyone have a broken/spare Coleman 4312 model furnace around? These were made in the 80s. I broke a small piece off mine when servicing and cant find the part anywhere.


I have checked ALL local/online plumbing/heating/rv shops.


I am hoping someone has a furnace that bit the dust and I can buy and pay for shipping on that part.

Here are some pics

It is a gas pipe elbow fitting. You should be able to find a suitable replacement part for it at an RV dealer who services propane equipment. This is not a part that is only specific to that make and model. It is more in the nature of a universal type of fitting. Take your broken part with you so they can be sure to match the thread size.


If you are trying to have them match the part to an old part number that will be an exercise in frustration. So you need to use the generic name for its function.

Went to 3 big RV parts stores. They all said good luck. It has an orofice at the end and it seems a tube was compressed to connect the two pieces

Someone that can silver (silfos) solder could probably repair that for you.
I have done fittings that broke before, and I don't know about your codes, but here it is totally legal to do. just clean it up nice, and solder. good to go.

I have the same problem as 78valleyForge and like Joe MacDonald I could only find Young Farts RV Parts with no luck there. How do I find Old Farts RV Parts?

Coleman furnace pilot light

After searching the web, I found that a Frymaster 8100148 also had this part, brand new. I got one on E-Bay for $20.00 out of Texas. Removed it from their elbow adapter and put it on mine, it fit perfectly. I have not installed it yet to see how it preforms, but have high hopes.
