Hey, that's great!

I think you should be able to get some parts just around the corner there. You know, just past Big Jim's and next to Blurpy's Imaginary Surplus.


Confused?

You need to tell people where you are (within reason) if you're going to ask "Where can I get ???".

Please don't presume we know. There are members on this forum from many different continents, let alone different countries.

So,...Where are you?

Today, plastic plumbing products designed for potable water applications are usually designated with either "NSF-PW" or "NSF-61" to indicate that the product complies with the health effects requirements of NSF/ANSI Standard 61 for materials designed for contact with potable water. This standard also establishes similar guidelines for other plumbing materials, including copper tubing. If your pipe is not coded with one of these designations or if it is designated with an alternative code such "NSF-DWV," it is probably not meant for potable water applications and should not be used for such purposes.

It is pressure rated.

McMaster-Carr has pressure rated fittings all the way up to 8".

So far, the web site has only failed me on certain small, insignificant things, like not having un-threaded male plugs, and things like that.

I've always thought that McMaster's part look-up process was rather fool-proof. Please don't tell me you are an advanced breed. :wink:

Just kidding. Click on "Pipe Fittings and Pipe" (first link on the page), click on "Plastic Pipe Fittings and Pipe", and then just narrow it down from there. It's pretty easy.

EDIT - a tip for pressure ratings. Get pipe fittings (SCH-40) that are rated as ASTM D2466. These are rated the same as the pipe (or 50% in the case of threads) when solvent welded correctly.

If you look again it does say "ASTM Specification
ASTM D1784, ASTM D2466"

Which, like mark says, means the fitting is rated as high as the pipe is.

It says its not rated to maximum pressure. It doesnt say it is not to be used with pressure.

If mark is right, im im almost certain he is, then the fitting is safe.

Well, then like frankrede said, look for an irrigation supply. They usually carry pressure rated pipe and fittings (required for pressurized water). If not, find a good plumbing supply house.

The Yellow pages would likely be a better resource than this forum, in your case. :wink:

Don't look for it in Big Box stores, look in the yellow pages for plumbing supplies...

Use Fastenal. There's one near my place within 2 miles, and I ordered (accidentally) over $100 worth of pressure rated 3" caps, bushings, and couplers. Their catalog is great (and usually free) and I definitely recommend them. The prices aren't bad, either.
