I ordered a check valve from devils own site for meth injection a week or two ago. A few days later I was looking through my parts and realized I had a solenoid so I didn't need the check valve.

It came in last night, and I checked to make sure it's there, havent touched it otherwise, it's the one with 1/8" npt male on one side and the quick connection for tubing on the other side.

It's $30 plus shipping from their site, I'll just sell it for $30 shipped if anyone is interested, if not I'll just keep it. Thanks
