Thanks for the suggestions. I'll have to try to find which storage box my old calipers are in. It looks like Lowes has a wide variety online, not sure what their in-store selection will be like. I guess I can take the needle valve into the hardware store to see what fits, I guess I'm just paranoid that I'll be accused of shoplifting if I take stuff into stores like that.
Does anyone know if I should try to match to the nearest metric or imperial size? Does it matter as long as it's a close fit?
