Rubber washers for Orbot?

[encaprodney]

Dave I don't see the grommets (rubber washers) listed separately for the bottle cap hoses. Hos has changed the design of the cap/hoses slightly and they no longer have the rubber grommets around the hoses going into the cap, but it is a better design because you can now twist on the cap without removing the jug which was always a pain. The part is inexpensive (P/N 2018).
