what did i break? help

What is this thing on the gas line? I unscrewed a nob on the bottom a bit and it wont screw back in. It was in my attempt to light the pilot. Here are some pictures

This is a picture of the inside of this very old furnace. The object im trying to identify is on the left. The one on the right is the regulator... right? Here is a close up

Its got some wires coming out of it, the gas line runs through it and the nob on the botoom screwed out but not back in

that is the gas valve, very old and crude design. You would be best to have the valve replaced and upgraded to standing pilot gas valve with a thermocouple. Or to replace the furnace. This is NOT DIY! You need to shut the gas off! Especially if you smell gas!

Locate the gas shutoff near the furnace and close it - you might need pliers...



Don't use it until you get it looked at.

Anything old enough to have that style of regulator/gas valve should have been replaced decades ago. It certainly doesn't meet modern safety standards, that's for sure.

I agree with Hvactechfw 100%

Find the gas shut off & call a local pro. No way, no how would I touch that online.
