You need a compressor that you can regulate down to 35 psi.
Why? PEX tubing and valves are rated for 160PSI of water @73F, I use 90 PSI of air which is much gentler and it works just fine.
The tubing is rated at 160 PSI but the crimped and screwed-on connectors are not rated that high. At 90 PSI you can cause a connector to fail. Normal water pressure is between 45-60 PSI so there is no real need for 90 PSI.
