What is the burst pressure of 1/2" black poly tubing rated for 100psi. I
want to bury it as an air line between my house and work building so it
will
have up to 125 psi in it. I have a lot of it for free that is why I want
to
use it.

100psi. g Bury it housed in PVC pipe so you can replace it easily
when it bursts on you.
