Thanks guys. I've got most of my fittings at local plumbing store, it's cheaper than order them online. The fittings that go into swagelok metering valve can be found only at their website. Clippard sent me solenoid + brass check valves and regulator was bought here on S&S. I don't remember exactly how much it all cost, but it was close to $150 including shipping. But I don't regret any dollar spent

Hope that helps
