Long story, but I'm having a hard time finding an in-line check valve for 3/8" tubing. Anyone seen such a thing sold for PC watercooling applications?

Quick disconnects seem to be the only similar thing, It's unusual to use a check valve since the pressure drop would make it pretty useless

Yea, the only one I've found (US Plastics) claims 1 psi drop in the flow direction (equates to about 3 ft loss of H2O head.)
