Product Details

This A/C compressor replacement service kit is built around the service parts commonly replaced during compressor repair on Ford E-Series vehicles. The accumulator measures 3.000 inches in diameter and 11 inches in length, with a 0.625-inch female O-ring inlet and a 0.750-inch P-nut outlet. The included orifice tube uses a standard black/white style with a 0.072-inch orifice diameter. Four Seasons 60078SK is intended for R134a systems that use an orifice tube design, making it a direct-service solution for select Ford E-150, E-250, E-350 Super Duty, Econoline Van, and Econoline Wagon applications.

This part cross-references Monroe Shocks & Struts (e.g., 551262, MUK60015) for the same application.
