    tubeless.Presta valve stem with a removable core . having a hard time sealing.

    i replaced my presta specialized tubeless valve stems with Stans Presta valve stem with a removable core on my Custom DT Swiss X420SL rims and having a hard time getting a seal around the valve stem base . i even added extra stans...:cry:
    any suggestions?

    Which Stans valve did you use? If you are using the Olympic Valve Stem it will not seal as it is made specifically for the ZTR rims...you should be using the UST Valve.

    I like to dip my valve stem (that sounds kind of kinky) into my sealant before installing, like this

    It's fairly common. Try hand tightening the nut as far as you can, then give it a turn with pliers. Once once you get a seal, back it off, so you can hand remove. If that doesn't work, I use this tape, which is sticky and moisture sealing. Put a small piece between the valve and rim. Works for me.

    Old enough to know better. And old enough not to care. Best age to be.
