Has anyone tried replacing the 9mm inflation valve with the large Ozone cabrihna slingshot inflate deflate valve?

The ozone valves are quite suscetible to bleeding air if there is even one grain of sand under the black o-ring. It can be a pain in the arse, why do you want to convert?

Liquid force and best have the best valves. No leaking air at all. I had a huge prob with airush valves last year, you would crash and it would pop open a little bit. Cabrinha I kept loosing the lid. But then you would have to mod your LE for the larg valve to fit.

ive got a 2013 14m RPM and it a 3 heart attack kite to pump up and just an idea that came into my head change it out instead of upgrading as the kites still pretty good.

It is simple if you don't have a problem with modifying your leading edge. I replaced the 11mm deflate valve on this kite with a First Generation Cabrinha one. I just carefully cut the hole bigger and bigger till it was a perfect fit. Although I have lost a lid at the beach as Kemp90 has, just make a habit of screwing it back on when your kite is deflated. I also patched over the 9 mm ball valve because it was also leaking.

Yeah right best this year have had a world wide valve nightmare, and liquid force Iover tighten it and it leaks air,, norths valve for the last two years is awesome, and a good shop can modify the fitting

This is correct but only for the valve delaminating. The valve its self is quite good. If your glueing them on yourself, you won't have a drama.

I really dig the LF valve. So far so good

Yeah I did.

However, I replaced the dump valve as the leading edge material has a bigger hole. The bonus being you can inflate your kite with the old style pump if you forget / lose the adapter.

I simply bought a boston valve for $5 from the local hardware store. Filed the plastic base (as it was a bit thick) and then made a ring with tear aid and placed it over the top to seal it.

The lack of complaints about that issue on here says your claim is simply not true. I have no problem with the valve, not do any of the dozens of people up my way that ride ozone kites. Several brands have actually switched to this valve as it just works and is super reliable.
You have to keep the rubber washer reasonably clean, but a few grains of sand will not be an issue, but a lot of sand will. You must refit the rubber washer the right way up, the side that is flat faces in to the base of the valve cap.

I'm actually with Chris here. I thought it was accepted that there was an issue when sand gets in them (even just a little sand) or if it's not done up tight and everyone stopped discussing it as that is just the way it is.

I've had Ozone forever and am happy but I am also super careful setting up to ensure it is sealed properly and I rarely have an issue. I however do occasionally experience a slow leak, but not often, maybe 3 times a year and always the valve just needs tightening or cleaning.

As said, I am super careful/aware of this so don't have many issues but someone not so careful or aware of this must have a more frequent issue.

IMO, if you're careful, it's a good system, if you're not careful, it might be trouble.

ps. I suppose anyone who has read this is now aware so there is no problem!!

It has been raised on here before, it's a nuisance if you forget to pull the o-ring off and clean it periodically, since I keep buying Ozone it's certainly not a deal breaker though. The one-way valve will eventually bleed air as well if sand gets in it, I just replace the red part and seals each season.

Perhaps its just a language and perception thing Jono/Chris? I used to clean the washer every time, now I hardly ever do, but I do make sure that I stick the valve in the neoprene valve cover and attach that back to the velcro on the LE, so there is less chance of sand getting under the washer or the one way rubber seal being damaged.
The one way seal is blown clean every time you inflate, by every pump stroke, and I've actually been out for a 2 hr session and come in to find to my horror that I'd forgotten to do up the lid!!
Small amounts of fine sand under the washer is not an issue, coarser sand, you need to be cleaner and more careful to check the washer, especially if you are not in the habit of keeping the valve in the neoprene (hat) valve cover when the kite is not in use.

What I do like about the large "boston" valve though is how fast the kite inflates and deflates!

Yeah, maybe. The one way valve definately is good. Loses no air. The inflate/deflate rate is great. Only issue I have found is the seal when screwing in. I suppose all systems would have the same potential for issues.

I'm just always conscious of it every time I pump up and if the kite has a wobble, my instant thought is that I didn't do up the seal right and the leading edge is going soft , although 99.9% of the time, nothing is wrong

We have fitted new North, Naish and Ozone valves to older kites with no problem. It is a little bit of work on some depending on the type of material around the valve.
