Protect Your A/C System: Vintage Receiver Driers & Filters
If you are resurrecting a vintage air conditioning system, the Receiver Drier (or Filter Drier) is the one part you must replace. This cylinder acts as the kidney of your A/C loop, containing a desiccant bag that traps moisture and debris.Once a system has been opened or sat empty, the old drier is saturated and useless.
At Old Car Parts NW, we stock authentic NORS (New Old Replacement Stock) receiver driers that fit your original brackets and look the part.
The "Sight Glass" Advantage
Modern replacement driers often look like generic black cans. Our vintage inventory typically features the built-in Sight Glass—the clear window at the top of the unit.
Diagnostics: The sight glass allows you to visually check the refrigerant charge (bubbles mean low charge, clear means full) and oil condition—a critical tool for maintaining vintage R12 or R134a systems.
Original Appearance: Keep your engine bay looking factory-correct with chrome or painted steel finishes that match the OEM style.
Why Replace It?
Prevent Acid: Moisture mixed with refrigerant creates acid that eats your compressor and condenser from the inside out.
Stop Blockages: Old desiccant bags often burst, sending pellets into the expansion valve and blocking flow.
Fitment: Specific units for Ford, GM (Harrison), and Mopar systems with correct inlet/outlet positioning.
