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.



I used that stuff for some outdoor water faucets in the garden. All of
it eventually failed (split) at the barb connections. I only run 40 psi
water pressure.

Actually it depends on which stuff he has. The newer poly pipes are
very good especially if he's got gas service rated. It's about all the
gas companies are putting in the ground now days.
