Thank you for sharing your feedback. We’re sorry to hear that you encountered difficulty inflating your tire after installing the product.
To clarify, the inflation nozzle operates with a one-way valve mechanism. Inside the nozzle, there is a pin that pushes open the valve core to allow air to flow in. If the inflating head of your equipment is not able to press this pin and open the valve core, the air won’t be able to enter the tire.
It seems that the issue you encountered may be related to the air inflating head, rather than the valve itself. We recommend checking the compatibility of your inflating equipment’s nozzle with the valve.
We hope this helps, and if you have any further questions or need assistance, please don’t hesitate to contact us.
Best regards,
