Frequently Asked Questions

Q: Do I need to remove these caps to check my tire pressure? A: No, the flow-through design is specifically engineered to let you gauge and inflate tires directly through the cap.

Q: What happens if the internal valve core of the tire fails? A: These caps act as a secondary seal that becomes tighter under pressure, preventing air from escaping even if the primary core fails.
