[Dcdiego91]

I have a heater model H120 120,000 btu port.

I need the NSN for the rubber wheel, I was able to find a part # but no nsn, and when I enter the information on fed log nothing is found. The part number I have is 40520. If you happen to ahve the nsn please share

What TM did you get this part number from? I looked in the TM for the heater in the TM form and came up with something very different. And that part number had an NSN. 2530-01-398-5396
So what TM are you using?
