I have two partially full canisters of refrigeration gas. The R22 is National brand, made in USA. It's a 30 lb. canister
that weighs 13.4 lbs. Based on the Tare (empty) weight of 6 lbs. it contains approximately 7.4 lbs. of R22.
The R404 is Arkema brand, made in USA. It's a 24 lb. canister that weighs 11 lbs. Based on an empty canister weight of 6 lbs. it contains approximately 5 lbs. of R404. I will take $100 for both.
