How we calculate scores →About this gear
The R251 is a 3-litre steel cylinder listed for rEvo use, with a 232 bar rating and an M25 × 2 neck thread. It is supplied bare, without a valve. Compared with the R252, both capacity and neck-thread specification differ, so this is more than simply a larger version of the same assembly.
Consider before buying
The current product description lists 3.9 kg, while the official 2025 parts list says 3.8 kg. Confirm the actual cylinder’s markings and supplied weight if trim or transport calculations depend on it. The listing does not establish oxygen-service preparation, valve compatibility for every configuration or current inspection status of an individual item.
Our take
Choose R251 when the exact rEvo setup calls for this size and thread, with the valve and mounting confirmed by the supplier. The 2-litre R252 is a comparison for a different configuration, not an interchangeable spare. No independent numeric overall review was verified, and the small weight discrepancy remains visible rather than being silently resolved.
