Do these fit my tire valve stems?

These are standard-size caps designed for typical tire valve stems found on most vehicles. Test-fit one on your valve before installing all four to confirm compatibility with your specific setup.

Will these caps prevent air leaks?

Valve caps seal out debris and moisture but are not primary air-retention devices. Your valve stem core does the actual sealing—these caps just protect it from contaminants.

Can I leave these on long-term without maintenance?

Yes. The anodized aluminum finish resists corrosion, but rinse them occasionally if exposed to road salt or harsh weather to keep the threads clean.
