i am not giving less than four stars review because i have compassion and empathy for companies and the products they make.with that said, these leak air and the tolerances which would permit these to not leak, must be reevaluated/reconsidered.i returned these, and purchased a similar item from a different company, here on amazon.i noticed that when these were tight, per specification, any movement of the valve stem extender permit air to leak. this poses a safety hazard because i cannot have my electric bike (vivi folding ebike with 48 volt, 20 amp hour capacity long range battery) achieving flat tires while en route. this is highly undesirable, and must be avoided at all costs (meaning, i shall avoid flat tires at all costs) this is why i have ordered solid (honeycomb) tires for my 14” ebike wheels, which cannot achieve flat tires. this is a wonderful, long term solution.meanwhile (while my solid tires are being shipped, which is a four to six week shipping duration), i shall use valve stem extenders on the ebike i am presently riding (as ordered from a different company). if this company can achieve zero air leaks from their product here, with design/tolerance improvement, i would be willing to try this product again, if, as needed.thank you.

thrown in to make the picture look good. But the metal caps have the rubber gasket for the true double seal. These things work better than they have a right to. You can orient them in any direction - I've got them on my bicycle. It's a serious commuter.
