Reseal your A/C system connections in one shot with the Four Seasons A/C System O-Ring and Gasket Kit 26039. It's an application-specific seal kit for a broad range of Freightliner trucks — including the CLASSIC, 2010-2013 COLUMBIA, CORONADO, 2006-2007 FLD120, and M2 106 — plus the 1986 GMC B6000; see the Buyer's Guide tab for the full list of years, models, and engine codes such as 6-11.1L, L6-12.7L, L6-14.0L, and V8-5.7L.
- Application specific: the seal selection is matched to the listed vehicles rather than a generic assortment.
- All the seals needed to complete the job: supplies the O-rings and gaskets called for on these applications.
- Dual-refrigerant compatible: works with both R12 and R134a refrigerants.
- Four Seasons pedigree: engineered and tested by a supplier with over 50 years of mobile A/C experience.
The O-rings and gaskets seal the joints and fittings throughout the A/C system so refrigerant is contained at each connection. If worn or hardened original seals are the cause of a refrigerant leak, this kit replaces them during service. Always diagnose the source of the leak before opening the system.
