Hey Guys if I shut off the main gas valve can I remove this valve? It is getting very hard to rotate it when I want to relight the furnace. If so what should a person lube it with?
If it is the small valve that you manually turn to light the pilot is what you mean I don't think they are serviceable. I would replace the entire gas valve and not try to repair the old one.
That furnace looks ancient from what I can see in the picture, you might consider a replacement.
Molykote 55 if you can get to the orings without damaging them.
Sounds like it would be safer if I just sent it to you for the overhaul. LOLwhen I was in the printing business we used a product on our rubber rollers to make them soft again we called it rubber rejuvinator it was nasty stuff ate paint, plastic and your skin but it worked great on rubber
