Summary
This APEX Design USA replacement cap keeps your RCV Rapid Connect Valve sealed when it loses its original. A missing cap invites grit and moisture into the one component your air system relies on at every corner - a cheap fix now versus a fouled valve on a trailhead later.
Best For
- RCV owners replacing a lost or damaged cap
- Keeping a couple of spares in the glovebox for trips
