Reseal the joints in your air conditioning system with the Four Seasons A/C System O-Ring and Gasket Kit, part number 26739. This application-specific seal kit supplies the O-rings and gaskets needed to complete the job. It fits many vehicles, among them the 1988-1991 Chevrolet C1500 4.3L / 5.0L / 5.7L / 6.2L / 7.4L, 1988-1991 Chevrolet K1500 4.3L / 5.0L / 5.7L / 6.2L and 1987-1991 Chevrolet Suburban 5.7L. See the "Vehicles it fits" section for the full list of applications and engines.
O-rings and gaskets seal the points where A/C lines, hoses and components connect, which helps keep refrigerant and oil inside the system. Signs these seals may need replacing include refrigerant loss, oily residue around fittings, or cooling that fades between recharges. Fitting new seals at each joint you open during A/C service is common practice. The listed applications use one kit. Country of origin: China.
