Do you HAVE a rubber seal ?
Asking, as I had one funny situation last weekend out with my 8 m2 kite.
I could hear it slightly "hissing" from the valve after it was pumped hard
(I always put the valve up to my ear before and after tightening the valve - this way I am 100 % it goes to non leaking)
Usually a leaking valve when rigging only happens if I get the line to the valve/cap stuck under the seal, so you just loosen and remove and close it again and now its tight
But this very kite did not have a rubber seal at all !
I have been riding around 1½ year with this kite, almost 100 sessions, maybe my most used size (out of 8 sizes), it has NEVER gotten flat or soft, just with the plastic ring on the boston valve closing fully tight towards the plastic on the LE side
Of course, at first when I used the brand new kite for the first time, I thought: The seal must be missing, or what ? Maybe some new material so you dont need the rubber seal nomore ?
As, when just screwed fine and tight, it was NEVER leaking for these close to 2 years
Till last weekend...
So I took a new rubber seal ring from one of the repair kits that comes with the kites, and voila - now it is healed and could ride the whole day not leaking now.
Apparently the plastic ring itself had such a perfect fit when new, that it was tight - till last weekend where wear and sand and me getting the line stuck under it, ha haaa.
All my other kites have the rubber sealing, so just curious IF you have this, or just by accident without knowing have had it without this sealing ?
As it seems to work fine for a while when brand new
