-220 to 140
Note: PT points are stored in psig and °F. For blends, bubble and dew represent different saturation states. Always follow OEM charging procedures.

Quick actions

These routes are designed to be technician-friendly: minimal taps, prefilled context, and predictable URLs for bookmarks and sharing.
