They don't fit. True, if you have a "new" pump and/or kitevalve, it will often not fit very well and pop out too easily, I was swearing a lot years ago when having the first of these.... When used and roughed up, it sits a lot better, so problem wears off in time. My latest kites from Storm Kites, h...

We call these "mini" boston valves, as their neck diametre is about 26mm. There are many sub-types of these valves, but mainly they fit into each other as the screw cap and threads are about the same. They are safely interchangable. If you're Cabrinha kite owner with Airlock V1 valve, V2 valve cap d...

This OZONE cap won't fit to Naish "green" valve. Kite brands use few version of "big" boston valves, I'm talking about the ones with approx 42 - 45mm valve necks.

And that is also what we meant on our site. We updated the text on our site to be fully clear. :bye: - Lately it has been discussed a...

Hello, sadly we can not do much work on genuine products themselves (eg. raw brand's valves), but contact us on info (at) drtuba (dot) eu and we'll try to help you with this issue. As I've mentioned earlier, go with universal solution or maybe try "fit on" solution, like Ozone's one pump valve (it's...

Hi, https://drtuba.eu/products/repair-kits-parts/kiteboarding-lines (we have both Liros SK75 & SK99 on stock) DHL service to US is 5 days, we ship worldwide. :bye: Playing devil's advocate here. If Liros kite lines are so superior, why is it almost impossible to have a set made and shipped to the U....

Links are updated now. DHL is 5 days to Hawaii from us. ;) Go with this: https://drtuba.eu/shop/product/deflate-valve-11mm-xl or better get new LE: https://drtuba.eu/shop/product/slingshot_rally_2014_12m_leading_edge if the old one has too much issues. :bye: I need some advice guys. Long story short...
