Safe thread sealant for grease trap drain pipe

Hey guys,
I am doing a bit of maintenance on my smoker, and wanted to fix a leaking issue. My grease trap drain pipe seems to be leaking through the threads. I've tried Teflon tape, but it still leaks. I don't know if it is safe to use pipe dope, since the first set of threads are in the cooking chamber. Does anyone have any suggestions?

From a safety standpoint, it simply doesn't matter. Your meat doesn't touch the threads does it? I don't understand why Teflon tape doesn't work, it should. Try dope or joint compound if the meat doesn't touch.

I figured using the wrong thing could let off gases with the heat involved. The meat will be only about 2 1/2 inches from the threads, so I would rather be safe than sorry. I'll try the dope and see if that works. Thanks.

Don't know what type of nipple you are using for your "pipe"....but brass threads are for the most part  self sealing.

My guess then would be that the leak is happening at the nipple where it enters the cooker. Metals of different thickness and material will expand and contract at different rates. Might try going with brass nipple and valve. Plumbers putty and pipe dope both have solvents.

If your weary of using pipe dope or Teflon tape you can use lampwick or fine mesh gauze to wrap your threads. Grease will swell material and create a seal.

There is no nipple. It's a 1"steel pipe that goes straight to the baffle plate/grease trap straight through the cooking chamber wall. I did put RTV around this section though.
