Summary
The APEX Design USA Flip To Deflate Cap hides a tyre deflator inside an ordinary valve stem cap - so the tool you need at the trailhead is already fitted to the wheel. Remove the cap, pull off the rubber cover, flip it over and screw it back on: the cap depresses the valve core and the tyre airs down while you watch the pressure. Reach your target, flip it back, and it returns to being the cap. No rummaging, no forgotten deflator, no borrowed kit.
Best For
- Drivers who air down at every trailhead and want the deflator always on the wheel
- Simple setups keeping standard valve stems rather than fitting valve systems
- Glovebox minimalists - the tool is the cap, so there is nothing extra to carry
- Four corners covered with the set of 4, or a fifth wheel with the set of 5

Fitment And Setup Checks

Frequently Asked Questions
How do I control how much air comes out?
The cap deflates while screwed on in the flipped position - watch your gauge and remove it when you hit the target pressure, then flip it back over and refit as the cap.
Will it deflate on its own while driving?
In normal cap position it seals like any valve cap. Deflation only happens when you deliberately flip it and screw it down onto the core.
Cap deflator or a valve system - which suits me?
The cap is the simple, always-there option for standard stems. If you want the fastest possible air-downs, the Rapid Precision Valve is the full valve-system route.
Fit them once and every trailhead starts with the deflator already on the wheel.
