Which refrigerant container may still be sold to a buyer without Section 608 or 609 certification?
Answer: D. A small MVAC can with a self-sealing valve.
- AA 25-lb cylinder of R-410A for home use.
- BA 30-lb cylinder of R-134a for a car shop.
- CA 10-lb cylinder of R-22 for a window unit.
- DA small MVAC can with a self-sealing valve.✓ Correct
Why D is right
Since 2018 the sales restriction covers HFCs as well as CFCs and HCFCs, so cylinders go only to certified technicians. Small cans of MVAC refrigerant, 2 lbs or less with a unique fitting and a self-sealing valve, may still be sold for do-it-yourself car repair.
