Just got some milkit tubeless valves... Great idea to stop clogging
Issue I'm having is when taking off the pump head... A lot of air escaping before I get chance to screw down the presta head
Now if I pull the presta head up as soon as I disconnect the pump head it closes the valve inside the tyre... But I'm still loosing a fair bit of air even as I do that?
Am I missing something? I'm use to just pulling off my pump from the valve and no air escaping so I can use my pressure gauge to see the psi I'm running... But when I attach the pressure gauge the same thing happens upon release so I lose another couple of psi
Any ideas what I'm doing wrong or is this just how it is?
Strange. I have two sets and haven't had this
Yep, I have the same issue.
Liked the idea when I bought them but with this and the added agro of adding fluid (I normally add through the valve) I kinda feel for me they’re an answer to some problem I never had. Nice quality valves though.
Mine work great, pump up as normal and I don't get any air escape. Big advantage is being able to check sealant levels and top up if necessary without popping off a bead and risking lifting the edge of my tape. I only tend to change tyres a couple of times a year though
Splodge phewwww thought I was being stupidly dim but glad to hear its not just me
I haven't bought the sealant syringe thing literally just the valves
They do pump up better no doubt and it's a better flow of air combined with the fact they don't clog
But the air escaping makes it really really hard for me to get a accurate psi reading
Rubber struggling see how you don't have any air escape as soon as I pull the pump head off its gushing it out... So if I put my gauge on release it I lose another 2 psi or similar meaning my digital gauge now becomes pointless
Unless of course we are both being dim and missing something ha
bump for morning crowd, anyone else found this?
I had this on my one of mine. I hadn't installed it correctly and the tube in the valve had pushed through to rubber end part and left it open. So when I unscrewed the valve loads of air came out.
It still wasn't that much of a hassle, as I could still put new fluid in, I just had to let the air go to almost nothing in the tyre.
The bigger problem I'm having is getting the valve to have a good seal on the rim I have. It works, but it relies on it being sealed with sealant and this breaks if I try to top up with air via a hand pump. Not solved this yet, but I'm hoping a strip down, clean up and re-install will solve it.
Actually, I think I've miss-understood your original query. I was meaning if I unscrewed the valve, I've never had problem with just using the presta valve 'normally', other than the "vigorous" hand pumping breaking the valve seal as described.
It sounds like yours are sticking open when they should close by themselves. If I want to let some air out I push the valve in like I would any other presta valve then when I let go the valve seals and no more air escapes. Sounds like you'd have to pull yours closed so I can only guess they are faulty, I can't see that you are doing anything different to what I do.
Only issue I've had was trying to remove sealant with the tyre at 20psi. I forgot to close the butterfly valve on the syringe and got sprayed with sealant 🙁
If you don't have the syringe you are missing out on the main benefit of the valves.....and they aren't cheap are they.
yep sounds like a different issue traildog
mines is purely just getting the pump head off or a digital gauge head off with losing loads of pressure
everything else seems spot on so far
