    There are two different products from the same company being confused 
there, I think.

    RapidAir Products makes RapidAir tubing, which is 1/2" OD nylon and 
rated for 150psi at the temperatures above.

    They also make Maxline, which is 3/4" OD hpde-al-hpde tube, and rated 
for 175psi at 70* F, and 140 psi at 140*.

    Which, now that I just typed that out, makes no sense.  I mean, it's 
hard for me to believe that the nylon hose is stronger at 180* F ( 150psi 
) than the aluminum-cored tubing is at 140*.
