White teflon will not seal gas or lubricants. I use yellow Rector seal #5 with reliable results.

FWIW, I worked as an HVAC mechanic and know there are teflon tapes rated specifically for Gas. But the only time I used teflon tape is when threads were damaged and I followed up with Megaloc on top of it. I
never like using tape as threads of tape can wind up clogging valves downstream.
I never liked using teflon as tape or paste as I found leaks later.
Megaloc works on everything including fuel, water, gas, gasoline, oxygen, acids, etc. My company wound up specifying it for all situations and it paid off in the long run. It's good stuff.

I will be very interested in this discussion as I plan to replace my exhaust riser assembly soon. I recently had a propane gas line installed in my house and the technician cringed at the telfon tape used on the existing pipe. Not the same thing of course,
but never would have expected teflon tape does not meet building code!
Also, if anyone reading this thread has a source recommendation for an exhaust riser/mixing elbow supplier, I would be grateful. Engine is a 1981 Yanmar 3GM 20 hp (not the 30 hp as in many boats).

I use Teflon tape on the pipe threads. A couple of wraps is good.

Here's a question for the mechanics in the group.
I am replacing the engine's exhaust riser or mixing elbow and associated threaded 1 1/4" and 1 1/2" nipples, and want to use the right pipe dope that can handle the heat and make a good seal and hopefully make
it easier to take apart for the next person.
I've been adised to use Never-Sieze on the bolts holding the flange and want to use Megaloc by Hercules on the pipe threads, but don't see any temperature stats on the can.
Any suggestions?
