OBA Check Valve

[loki_racer]

I can't find anyone local tool or auto parts stores that sell an air check valve. I'm headed to The Flats tomorrow and the only part I'm still missing for the build is the check valve.

Anyone know where I can get one tonight in Charlotte? Anyone able to bring one tomorrow to The Flats?

I got mine from a local plumbing supply place, made for water, but works for air too
