All American Canner Pressure Cooker 15.5 Qt

All American pressure Canner/Cookers feature an exclusive, precision machined "metal-to-metal" sealing system. Positive action clamping locks align the cover to the base, forming a steam-tight seal. At the same time, this metal-to-metal seal automatically permits venting under unusual pressure conditions providing an extra margin of safety over conventional rubber or composition gasketed cookers.

• Exclusive metal-to-metal seal, no gaskets to crack, burn, replace or clean
• 5, 10 and 15 pound pressure regulator weight
• Positive action clamping wing nuts permit easy opening and closing
• Double thickness edges for additional protection on these points of heaviest wear
• Automatic overpressure release
