    New question here. RockShox Speed Lube kit: lost suction

    So I pulled out the RockShox Speed Lube kit to do a quick splash-oil change, only to find out that it no longer has any suction to suck up oil or push out oil. It's as if the plunger shrunk or syringe expanded, no longer having a tight fit/seal. (Does fork oil affect plastic syringes?)

    Anything I can do the expand/shrink it back to a normal fit/seal? Or does this mean it's simply dead; discard & buy new?



    I also have the Avid Brake Bleed kit (even older), and those syringes/plungers are totally fine. (I guess Dot fluid doesn't affect plastic syringes?)

    Thanks for your info in advance,

    Isn't there an o-ring on the plunger you can replace?

    A dumb question here, but "o-ring" as in the whole "rubber chunk/piece" at the end of plunger? (Or is there really a separate more-conventional "o-ring" on it, which I don't see it on mine?)

    If so, is this really a SRAM-replacement piece, or something from a local hardware store?

    Can you move the threaded fitting over to any other syringe?

    I meant o-ring but if you have the cone shaped rubber tip you're probably better off just getting a new syringe.

    Mine did the same thing a few years ago. My quick fix was to wrap a rubber band around the wide groove in the black rubber to build up the end. It wasn't perfect but it worked well enough and was free.

    Good job! cheap replacement syringe

    So, instead of buying a whole new kit for $30~, I found this syringe for $6 (on sale) at Amazon.

    Large Plastic 100ml Syringe + 80cm handy plastic tubing:Amazon:Industrial & Scientific

    What's really cool is that the tip of this syringe happens to have the exact threads to accept the Speed Lube piece.

    I'll be doing oil change on my Totem tomorrow.

    Eh, any luer lock syringe would have worked, I bet you can get one for less than a dollar at your local pharmacy.

    You could clean off the plunger from the brake bleed kit and use it in the speed lube kit since you had both, this is what I did.
