Choose a camping gas cartridge by the exact connection and fuel specification in the appliance instructions, not just by the words butane or propane. Two cartridges can contain similar fuels and still belong to different connection systems.
These three documented families illustrate the distinction. They are not an exhaustive list of regional camping cylinders or cartridges.
Three connections that should stay separate
| Family | Documented example | Compatibility information to keep |
|---|---|---|
| Screw-on cartridge | MSR PocketRocket 2 | The manual specifies its cartridge type and fuel blend; retain both |
| Campingaz CV self-sealing valve | CV 270 Plus with Easy Clic or Easy Clic Plus equipment | Match the CV family and the appliance’s listed cartridge compatibility |
| Pierceable cartridge | Campingaz C206 family | A pierced cartridge is not treated like a detachable self-sealing valve cartridge |
The PocketRocket 2 manual specifies an MSR cartridge with an 80% isobutane/20% propane mixture certified to EN 417. The standard marking is one part of that specification, not permission to attach any container bearing it.
Campingaz separately identifies CV 270 Plus for Easy Clic and Easy Clic Plus equipment. Its Twister Micro Plus stove page gives a named appliance example using CV Plus cartridges. These records are more useful than a broad listing that says only “camping gas.”
Why the valve matters when packing
A self-sealing valve can permit disconnection while fuel remains, where the appliance instructions allow it. Campingaz explicitly describes that capability for CV 270 Plus.
The C206 pierceable example has a different constraint. Campingaz’s 2016 cartridge catalog identifies it as a cartridge that cannot be disconnected from the appliance until empty. That historical document establishes the construction distinction; it is not evidence of current availability or permission to use an old appliance without its own instructions.
Do not assume that two small, similarly shaped cans share the same removal procedure. If you cannot identify the connection from the model’s documentation, resolve that before selecting fuel.
Make a fuel record before the trip
Record the appliance model, approved cartridge designation, required fuel specification and the matching manual. Check the cartridge label against that record. Keep a photograph of the label so a replacement can be identified accurately at your destination.
If the listed cartridge is unavailable, a similar fuel name does not establish a substitute. Ask the appliance manufacturer about supported options. This comparison does not certify adapters, modified fittings or refill arrangements.
Use gas equipment only within its documented operating conditions. The MSR example is explicitly for outdoor use; a tent is not a substitute for an outdoor cooking location.
This is a manufacturer-document comparison checked October 12, 2026. No cartridges were connected, burned or cold-weather tested for this article. Connection permission, safe operation and transport requirements remain model- and location-specific.
