Parker 450254-001 Drier

The Parker 450254-001 is a 30-cubic-inch liquid line filter drier designed for high-performance contaminant control in residential and commercial cooling systems. As the direct updated replacement for the 033000-305, this LLD-305 model features 5/8" SAE flare connections, offering a secure, mechanical fit without the need for brazing. Its molded molecular sieve core provides exceptional moisture removal and acid neutralization, making it fully compatible with modern HFC and HFO refrigerants including R-410A, R-134a, and R-404A, as well as POE and mineral oils. The steel shell is finished with an epoxy powder coating to resist corrosion in harsh environments, maintaining a 650 psig maximum working pressure. This unit is an essential HVAC service part for ensuring system longevity by capturing solid debris and preventing TEV freeze-ups or compressor failure.

• Direct Replacement: Seamlessly replaces legacy 033000-305 and 305 5/8" SAE units.
• High Capacity: 30 cu. in. volume provides superior water and acid capacity for systems up to 15 tons.
• Corrosion Resistant: Epoxy powder-coated finish exceeds standard salt spray testing requirements.
• Universal Compatibility: Optimized for use with all standard CFC, HCFC, and HFC refrigerants and their associated lubricants.
• Easy Installation: 5/8" SAE flare fittings allow for quick field replacement and leak-tight connections.

• Is the Parker 450254-001 compatible with R-410A systems? Yes, this solid core liquid line drier is rated for 650 psig, meeting the pressure requirements and desiccant compatibility needs of high-pressure R-410A systems.
• Does this drier replace the 033000-305? Correct. The 450254-001 is the official updated part number for the 033000-305 5/8" flare drier.
• Can this be used for system clean-up after a burnout? While this provides excellent filtration, it is designed for permanent liquid line protection. For heavy burnout clean-up, a suction line drier alongside a liquid line drier is recommended.
