Reseal every refrigerant connection you open with the Four Seasons A/C System O-Ring and Gasket Kit 26005. It's an application-specific set of the O-rings and gaskets used to seal the air-conditioning line and component fittings on a wide range of BMW models, including the 2016-2017 120i, 2012-2017 320i, 2014-2016 328i, 2016-2019 330i, 2013-2017 640i, 2013-2017 650i, and the 2015-2017 M3 and M4 — see the Buyer's Guide tab for the full list of covered vehicles and years.

  • Purpose-built kit: supplies the sealing O-rings and gaskets you replace whenever an A/C fitting or line is disconnected during service.
  • Fresh seals: installing new O-rings and gaskets helps restore a leak-tight joint at the connections you open.
  • Model-matched coverage: assembled for the listed BMW applications so the right seals are on hand for the job.

If aged, cracked, or flattened O-rings are the cause of a refrigerant leak at a serviced connection, these fresh seals replace them. Always evacuate and recharge the system per the vehicle service procedure and use the correct refrigerant and lubricant.
