If the Dubro you bought has a black stopper, do not use either the stopper or the tubing in the bag. Only the reddish-brown Dubro stopper is "gas usable". Silicon tubing that works for nitro will NOT work for gas; you need tygon (yellow), neoprene (black), or Viton (black, smoother feel).
Bob,
Do you have any experience with K&S Sta-Flex?
