That is not the same one, but the first one on the list should work. The ones listed there are for washer fluid, but should handle vacuum.

Allow the plenum to evacuate

Allow the plenum to evacuate, but block the reentry of air, or loss of vacuum.

The subject line of the post says it is for washer fluid.

Did not re read that. I also commented on one where the check valve for the HVAC was not working.
