i have a few stupid questions :p

1)if i have a hole pile of pn18 pvc fittings and i make a chamber out of them but join them with pn12 ( or whatever the equivalent to sch40) pipe would the chamber be able to hold pn18 pressure or would the pn12 let it down?

2)and a chamber made of of pn18 fittings joined with other pn18 fittings would it be pn18 pressure rated? right?

3)oh and how much pressure can a pn18 fitting hold?

sorry if these questions dont make sense or are rely stupid, its late

Well, the pn12 fitting will probably hold up, but you will have exceded the rating and possibly weakened them.
I think pn18 is 260 psi and pn12 is 170psi, correct me if I'm wrong.

Idon't know these standards but I pretty sure that a chain(or chamber) is only as strong as its weakest link

1: Unless if you cover every bit of PN12 pipe with a PN18 fitting it wont be as strong as PN18. I wouldn't trust it to 290PSI though.

2.Yeah.

3.PN18 means 'Pressure Number 18 BAR' or 252psi.
PN12 means 'Pressure Number 12 BAR' or 168psi.

thanks chaps you have being a huge help
