    anyone reccomend an air compressor nozzle that actually FITS over presta adapter?

    im trying to add more stans but the threads on the presta adapter dont allow the compressor nozzle to go over it.
    when i screw down the presta adapter tighter (so the actuator is closer to the top of the presta adapter and had a better chance of contacting the trigger inside the compressor nozzle) it only ends up pulling out the valve core completely. i know i did it once but maybe it was just luck.

    this nozzle will fit over the shraeder valves in my car tires no problem, but not the presta adapter for the bike.

    Just buy a presta->shraeder adapter. It screws onto the presta valve and will fit any compressor fitting.

    arrgh,, FINALLY after fiddling around with the other assorted nozzle attachments and was able to get it seated. that only wasted an hour.

    the problem was:
    inner diameter nozzle A would not fit around threads of B, preventing it from activating the center thingie to release the air.
    maybe it's just a REALLY old presta adapter and therefore has larger thread diameter? damned if i know

    finally,, screwing B into C into D, i was able to just push the whole thing around the open presta valve and get enuff of a seal (even without the adapter being screwed onto it), to get enuff pressure to seat the tire. the rest i was able to do with a floor pump... still 2 hours oof daylight left,, im out,, thanks,

    The problem is A, those are horrible for bicycles, schrader or presta. Get the long ones with the dual-sided head.

    I had the same problem. My solution was to tighten the valve core a little tighter. Works fine for all my tires now.

    and of course 20 mins out into the ride my rear derailleur cable snapped. luckily it was right where it clamps into the derailleur bolt so there was still enough cable to reattach it for a SS ride home...

    I've had this same problem with the nozzles at gas stations lately. Never had a problem up until the past couple of tubeless conversions I've done. Not sure what the difference is as my presta/schraeder adaptor is the same. Very frustrating.

    That's why I like the slide on ones. Gives a little wiggle room. I have notices that the last two sets of peseta stems I installed (not sure what brands but both pairs different and removable core) the nut screwed out a turn or two less it seemed. I only noticed because I didn't bend them right away like I always have in the past. And here I thought I was just getting better at it/being more careful!

    They also come in black. I bought these a few years back, because I got tired of messing with an adapter kit. No problems ever since. I think a LBS on the far west side of town sells them also.
    Tubeless presta issues no more!!!
    I think I'm not as good as I thought.

    I can't see having another pair of wheels without these or something similar. Presta is a pain in the ass. But, then again, the majority of you likely are worried about weight and shaving milliseconds off your Strava times. I'm not, so I've got wide, heavy rims that will accommodate a Schrader valve. Many rims won't.

    +1 for the Prestaflator, though. Since I have one of them. Just get the attachment, though. I've found the gauge on the actual "gun" to be not terribly accurate.

    What I ended up doing is making a hybrid air pump with about 25 bucks in parts off amazon and some fittings from Lowes anyone reccomend an air compressor nozzle that actually FITS over presta adapter?-imageuploadedbytapatalk1361175793.653779.jpganyone reccomend an air compressor nozzle that actually FITS over presta adapter?-imageuploadedbytapatalk1361175810.798533.jpganyone reccomend an air compressor nozzle that actually FITS over presta adapter?-imageuploadedbytapatalk1361175832.525774.jpg

    It was a pretty easy DIY project. If I did it again I would get a different hose end from sks but for now this works great

    Cheap and easy tubeless inflator setup

    Buy this inflator from your local Walmart (same one as the post above mine, but modified differently). Use a wrench to unscrew the brass head (from the end of the red hose) and remove the little floating brass nipple inside but leave the rubber O-ring in there. Screw it back together. The floating piece you remove is the part that opens a shrader for inflation and since you're using a presta, you wont need the part. The head of this inflator easily fits over a presta/shrader adapter and there's a spring-loaded lever that holds the nozzle in place while you inflate. Best $18 I ever spent.

    I have been scrounging old tubes from an off road motorbike shop - cut out the schraeder valve and they have a proper hex nut on the full length threaded valve body to lock it onto the rim - much simpler to refill through the larger valve and more robust that presta!
    Growing old is mandatory - growing up is optional

    Frickin awesome! Just read this, because I have the same issue. Clicked your link to see what that was and realized I have one laying around and threw it in a drawer because it did not work for me. I will give this a shot!

    Thanks!

    Hope it works out for you. The only drawback is that the bleeder button doesn't work for this application, but tubeless setup works really well.
