There are hundreds if not thousands of online stores that sell pipe and fittings of all sizes.

http://www.mcmaster.com would probably be your best bet... It has pictures and stuff.:wink:

I (for example) was looking at 4" elbows... I could only find drain :( . Am I being stupid and not seeing one or do they not have it? Also, am I mistaken or the few pressure rated items I did see were going for about 25 dollars?

Yes, MC-Master is the best way to go. I would suggest that you reduce your pipe a little (maybe to 1 1/2 inch?) for all your turns and whatnot, and then enlarge it again for whatever...

I am saddened by people only suggesting mcmaster.
There are more general supply sites other than mcmaster!

http://www.builderdepot.com/
http://www.grainger.com
http://www.mscdirect.com/

Mcmaster is way too high priced to rely upon for everything.

I was looking at www.sprinkler.com and they had this pressure rating list for their fittings. Anyone know if the ratings are 100% right?


Sch 40 Fittings-
Schedule 40 (Sch 40) fittings are rated on wall thickness. Due to this fact the pressure ratings for the size of fittings will vary. The pressure ratings are as follows:

Fittings Size Pressure Rating
1/2" Sch 40 Fittings 600 psi
3/4" Sch 40 Fittings 480 psi
1" Sch 40 Fittings 450 psi
1 1/4" Sch 40 Fittings 370 psi
1 1/2" Sch 40 Fittings 330 psi
2" Sch 40 Fittings 280 psi
2 1/2" Sch 40 Fittings 300 psi
3" Sch 40 Fittings 260 psi
4" Sch 40 Fittings 220 psi
6" Sch 40 Fittings 180 psi
8" Sch 40 Fittings 160 psi
10" Sch 40 Fittings 140 psi
12" Sch 40 Fittings 130 psi

Are all of the 4" fittings on sprinkler.com 220 psi? I think that is what it says, but I don't know.
