tune Válvula tubeless en set de 2

I had to throw the inner valves away. That was not because of sealant because I always seat the tyres without sealant first. The factory inner valves almost release no air, so lowering pressure takes forever.
One O-ring was too big and both o-rings protrude from underneath when fastened. That is not from tightening too hard, because I press with my thumb on the rim side of the valve when tightening, so less or no pressure and rubbing between ring and rim occurs.and the result is still tight enough. In time I have to find another solution for these rings.
Never encountered this kind of problems with tubeless valves before.
Length is good, colour is nice. But I buy them to be functional out of the box, so minus 2 stars.
