Can a union hold prolonged pressure?

[Mihlrad]

Can a sch 40 union be used as a part of the resevoirs or will they be unable to withstand about 110 psi.

if a sch 40 wouldnt work, would sch 80?

[noname]

SCH 80 would work, people use them in hybrids, SCH 40 would probably work. Now 2 questions
1. How long will they be pressurized?
2. What for?

[Velocity]

don't use sch 40 unions in chambers for prolonged pressurization. It will probably work, but I just wouldn't risk it. Use SCH 80 unions, or better yet, cam locks!

[Mihlrad]

The cam locks would cost me an extra 20 dollars for my idea.+ shipping of 5 dollars.

why do you think they use them in house hold plumbing

[rna_duelers]

Well if the part is designed to hold pressure for prolonged periods and they are deisgned for it there is no reason why not.

why do you think they use them in house hold plumbing

household plumbing does not consist of pressure like 100 psi.

[SpudStuff]

it is 275 psi comming off the water main at our house and 120 through the rest of the house

[Mihlrad]

Yea, and off of the freaking water main does not use pvc... Im not gonna argue with you.

[SpudStuff]

actually the main to the house is 1.5 " pvc

[drac]

Plain and simple, PVC WILL hold up when the PVC union is used. If your concernec about sealing issues, don't worry it's fine.
