Rated to 46psi, I'd say no. A metered propane combustion gun can theoretically produce 82-86psi, this is too much of a pressure spike for pipe rated to 46.

Though there's continual debate on the topic, I prefer cellular core ABS for combustion guns - if it DOES fail, it rips clean with no shrapnel (as far as my testing can tell...). It's also dirt cheap.

NSF-PW PVC is always considered the best.

Peace,
Pete Zaria.

i have seen sewer pipe used before, but it was rated to more PSI than that. I would not use that low rated pipe. Combustion makes alot of pressure too, i wouldnt risk it. JMO

do you have an air compressor. if you do put a chuck in a small piece of the pip and hook the air compressor on it and turn it on hiding behind a wall and if it blows up don't use it if it doesn't you can.

i would bet that if the combustion chamber was only about 8 inches or so and had a coupler in the middle it would be ok, but probably not worth it.
