Detailed Description

Global Parts 4812520 is an automotive A/C hose assembly used in HVAC systems to route refrigerant between major components. In air conditioning service, suction hoses connect the compressor to the evaporator, discharge hoses connect the compressor to the condenser, and liquid lines connect the condenser to the evaporator. This hose assembly serves the refrigerant path required by the listed Nissan and INFINITI applications, including 2009-2019 Nissan 370Z, 2009 Nissan 350Z, 2007-2008 INFINITI G35, 2008-2013 INFINITI G37, 2008-2012 INFINITI EX35, and 2013 INFINITI EX37.
