Pressure Ratings

If a piece of pipe is rated to "NSF 61" does that mean its rated to a max of 61 PSI?
Because I found a cool schedule 40 fitting, and I cant find what it's rated to. I would think it'd be rated like any other sch40 fitting.

Not at all related to pressure, it just means it complies to
this standard - so basically, your piece of pipe is safe to drink out of

This website was the first site Google recommended when searching for "nsf 61"
research research
This site explains in a whole lot more words what jackssmirkingrevenge so very well summarized.

So should I just go ahead and get the fitting? It's sch40, and that is a basis on how thick the pipe walls are. I would assume that it is rated just the same as any other sch40 fitting.

Wrong.
Sch-40 means nothing.
No pressure rating means no pressure.

Well it's clear pipe, that's why there arent any words on it. No words = No idea if it's rated or not.

It's probably safe to use as a combustion chamber or as a barrel but I wouldn't trust it as a pressure chamber for a pneumatic.

It actually was for a pneumatic.

Trust me, you'll get a lot more buzz with clear pipe if you use it for a combustion

I have yet to see a pressure rating on any PVC fitting, and everyone uses 'em.

NSF-PW and NSF-61 fittings are both perfectly safe to use in pressure applications. Your fitting is absolutley safe to use in a pneumatic or a combustion. (I would recommend the combustion)

* I assume as we use the same pipe

I have yet to see a piece of pressure rated pipe of fitting that doesn't have atleast nsf-pw or a pressure rating.
My fittings have nsf-pw and my pipe has nsf-pw and a pressure.
