Gasoila looks like a good product, and it is rated for heat up to 600 degrees.  
I think Megaloc is superior.  Diesel exhaust can be 1000 to 1200 degrees so I'm 
still looking.

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?

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 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?

Found Megaloc rated to 400 degrees.  That's the normal temperature of a diesel 
exhaust but it can get up to 1000 degrees when stressed or when there is a 
problem, so I might look for something else.

I’m not a mechanic and have not played one on TV.  Based on the recommendation 
of a very good mechanic, I stopped using Teflon tape and now use Gasoila on 
everything with a pipe thread connection (hot or cold).

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

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.
