Brake air hose for 105

[Armada]

I just picked up an M105 that has a chunk missing out of the air hose between the glad hand and where it attaches to the trailer. I can remove it from the trailer and remove the G-hand which leaves me with just a section of hose that I would think any well stocked automotive store could make up, like NAPA. What is the psi rating needed for the hose? Does anyone offhand know who has NOS? Useable tak-offs?
Thanks

It's a stock airhose.. Any decent truck stop will have it.
