AC Avalanche Blaster Recharge Hose Adapter

Self Sealing Valve Recharge Hose Adapter All new 2018 AC Avalanche products with R-134a refrigerant are equipped with EPA mandated self-sealing valves. Most refrigerant products pre-2018 were equipped with a piercing-style valve which remained open and could leak refrigerant if used improperly. As required by Section 608 of the EPA Clean Air Act, all refrigerant cans are required to have a self-sealing valve which remains closed when the recharge hose is removed.
