IR SSR-EP200/50 Air Compressor

I have an IR 7.5 hp , it's set for 175 psi , the Fast Pipe air line I would like to use is rated for 190 psi . That seems like not much buffer for air pressure. Will it be safe?

I made my first air line out of PVC SCH. 40 , but I think that was a mistake. Don't want to screw up again.

Thanks,

Bill
