Home Depot sells those same gas line tubes with flared and (IIRC) brazed endings, so theres no reason you couldn't make this thing tight enough for decades of operation. People use them in ghetto refrigeration systems already, and those often have 200+ PSI in them. Ditch the plastic for copper and you're good to go.

Edit: And put a $0.75 shrader valve on there. That way you can pump the pressure as high or low as you like.
