Flame King manufactured this 12. 2 gallon RV propane cylinder to ASME specifications in facilities that have a Quality Management System certified to ISO 9002 requirements.

NOTE: Fits in a 26ft GMC Motorhome but requires minor trimming of the collar to allow for a snug fit and compartment door closing.

The advantage for ASME cylinder vs. DOT is that they do not require recertification after 12 years from Date of Manufacture.

The unit has the fill valve, relief valve, and level gauge installed with high-grade steel welded construction that is powder coated for long lasting exterior protection. It is X-ray and hydrostatic tested.

This tank is 12. 3″ diameter, 28″ in length and the height including the collar/bracket is 15. 5″. The collar on it’s own is 4″.
