Replace worn or leaking A/C service-port valve cores and caps with the Four Seasons A/C System Valve Core and Cap Kit, part number 26780, a cap and valve seal kit designed to help seal your air conditioning system's service ports. It fits many vehicles, among them the 1997-2003 Ford F-150 4.2L / 4.6L / 5.4L, 1994-2009 Ford F-250 4.6L / 4.9L / 5.0L / 5.4L / 5.8L / 7.3L / 7.5L and 1997-2010 Ford Explorer 4.0L / 4.6L / 5.0L. It is a direct-fit replacement for the listed applications; see the Buyer's Guide tab for the full list.

Valve cores seal the A/C service ports while still letting the system be charged or recovered through them. The caps cover the ports to help keep dirt and moisture out. This kit supplies both in one package.

  • Seals for the whole job: Four Seasons includes the seals needed to complete the job in one kit.
  • Two refrigerants: Works with both R12 and R134a refrigerants.
  • Application-specific: Intended for SUV and rear air applications, as listed.
  • Plastic caps: The caps are supplied in red, blue and black.

Four Seasons engineers and tests its products and brings more than 50 years of mobile A/C experience to them.

Signs these parts may need replacing include a refrigerant leak or hissing at a service port, a missing or cracked cap, or a gradual loss of cooling performance. If a leaking valve core or damaged cap is the cause, this kit replaces them. Diagnose the cause of any refrigerant loss before replacing parts.

The listed applications use one kit. Country of origin: China.
