Any auto supplier, they use them in just about all FI
cars as "one way air valves", about 5/16 ID hose push on
fittings but you can add hose clamps externally.

Ooops. When the "pop" happens it will blow the absolute
crap out of your container and fittings. What volume of
gas will you have in the container where it can pop?
Don't underestimate the explosive power of even a small
quantity of gas, a fist sized volume will blow the sides
out of a heavy gauge steel welded container.

I'd love to see your design. Before you blow it up. :o)
