Hybrid(?) Diffusion Stone

[ErinGoBuff]

Has anyone come across a 1/2"NPT in-line diffusion stone with either a check valve or a 1/4"MFL integrated with it? ...so I can add a check valve.

I'd love for my oxygen line to stop taking in wort on it's way past the stone.

I have not seen what you are looking for but could you just turn on the oxygen before submerging the stone. Seems like the pressure would keep the wort out of the line that way.

That's logically true, but this is part of an in-line system. If I try to not over-oxygenate my wort, or if I'm conserving oxygen, or, conducting CIP, liquid will backflow through the stone.

Another simple solution is to add a 1/4"mfl swivel via an easily cleaned pigtail, but I would prefer having a dedicated piece of gear to rely on.
