Four Seasons 33169 A/C Accumulator Overview

Product Details

The accumulator is a key component in the vehicle air conditioning system, helping manage refrigerant flow and moisture control on the low-pressure side of the HVAC circuit. Four Seasons 33169 measures 3.500 inches in body diameter and 8.000 inches in body length, with a 3/4 inch inlet and 3/4 inch outlet. The aluminum construction supports corrosion resistance in underhood environments, while the OE-style fitment details make it a practical replacement for service work on older GM truck platforms and select Audi and Pontiac models.
