Hello Reddit rafters. I recently purchased an older raft with Halkey Roberts valves, all of which are missing their cap. These are the old and discontinued 690-BV values with the long-stem cap. The new 690-NSBV and old 690-BV short-stem caps do not fit the old long-stem valve. I am looking to buy 6 of the old long-stem caps if I can find them, which is a challenge, so I am trying the power of Reddit. If anyone has some of these and you are willing to part with them, please let me know. Or perhaps you know someone else that might have some. Thanks for looking and any assistance in locating these caps is greatly appreciated.
