Detailed Product Description

The Four Seasons 33430 A/C receiver drier is engineered with a steel body that measures 2.5 inches in diameter and 8 inches in length, providing a robust housing for the internal desiccant material. The desiccant is non-replaceable and is designed to trap moisture and contaminants from the refrigerant, preventing corrosion and damage to the A/C system. Both the inlet and outlet fittings use male insert o-rings, ensuring a tight seal and leak-free operation. This part includes green o-rings ([24606] and [24608]) to maintain system integrity during installation. While the mounting bracket is not included, the part meets or exceeds OEM standards, making it a direct replacement for the BMW 735i's original component.
