FORANE by Arkema R-407C Refrigerant 25 LBS R22 Replacement, Open Tank

Description

Up for sale is a 25lb cylinder of Forane 407c refrigerant.  The tank is sealed in the box but the valve tamper seal has been broken.
Shipping weight is 32.10lbs so the empty bottle should tare out to 7.10lbs.
My scale shows a bottle weight of 31lbs so approximately 1 pound of 407C was used.
