Product Details

The Four Seasons Filter Drier line is used in automotive air conditioning systems to trap contaminants and remove moisture from the refrigerant circuit. On applications such as the 1968-1974 Cadillac DeVille, 1968-1973 Pontiac GTO, and 1968-1972 Buick LeSabre, the receiver drier helps maintain cleaner refrigerant flow and stable system operation after service or component replacement. Part number 33213 uses a steel body, female insert O-ring connectors, and a non-replaceable desiccant design with no service port, switch port, or mounting bracket included.

This part cross-references Monroe Shocks & Struts 172289 for the same application.

Installation Notes and Tips

Replace the receiver drier any time the A/C system has been opened for service, especially after compressor failure or major refrigerant loss. Verify 3/8 in. inlet and outlet sizing, female O-ring connection style, and overall dimensions before installation. Use the included green O-rings during assembly, and evacuate the system before recharging to help remove air and moisture.
