This neat item PREVENTS Back-flow by allowing the fluid to pass in ONE direction ONLY !!!

Just insert one of these goodies into the tubing and it does the rest !

This can be used in place of a straight connector as well, such as between tubing and an Inflatable Nozzle !

The connections are tapered, so they'll fit 5/16" or 1/4" Tubing very nicely. Naturally, this restricts the flow a little, so we recommend hanging the bag higher to increase the "feed" pressure.
