MSR - Fuel Bottle - 20 oz.
 
Designed to work with the threaded pumps on your existing MSR fuel.  Air-tight seal allows fuel to be stored longer by preventing air from entering and degrading fuel.  Made from single-piece, impact-extruded aluminum to prevent leaks and cracks.  Bolstered shoulder and base to resist bulging when pressurized. 
 
Assembled in the USA of imported parts.
