Parker LLD-053 Liquid Line Filter Dryer 5.2in 650 psi
A liquid-line filter dryer with a 75/25 desiccant blend for all CFC, HCFC and HFC refrigerants, 5.2 in overall length and 650 psi rating
- Removes moisture and acid with 75/25 desiccant blend
- Handles R-22 and R-410A systems up to 2 ton capacity
- Withstands 650 psi working pressure for reliable operation
- Compact 5.2 in length fits tight installations
- SAE flare connections simplify installation on copper lines
Application fit
The Parker LLD-053 is a liquid line filter dryer built for HVAC and refrigeration systems using CFC, HCFC or HFC refrigerants. It suits technicians who need a 5.2 inch steel shell with a 3/8 inch SAE flare connection and a 75/25 desiccant blend rated for 650 psi working pressure.
Sustained operation
Under continuous flow the 75/25 desiccant blend maintains moisture and acid removal across the full 2 ton R-22 or R-410A capacity rating. The steel body holds the 650 psi rating without deformation, so the dryer keeps protecting the circuit through long cooling cycles and repeated pressure swings.
Replacement context
This unit replaces an existing liquid line dryer when the desiccant is saturated or the shell shows corrosion. The jump is worth it when the system requires a 5 3/16 inch cut-out length and a 3/8 inch SAE flare fit, and when the refrigerant mix calls for the 75/25 blend rather than a straight molecular sieve.

Questions about this item
Does the 650 psi rating mean the filter dryer runs hot or makes noise during continuous operation?
The Parker LLD-053 is a passive component with no moving parts, so it generates no noise and adds negligible heat to the refrigerant circuit.
What existing refrigerant lines or fittings do I need to install this 3/8 inch SAE flare filter dryer?
You need 3/8 inch SAE flare connections on both the inlet and outlet of your liquid line to match the filter dryer’s fittings.
Will the 75/25 desiccant blend work with the R-22 still in my older system?
Yes, the filter dryer is rated for all CFC, HCFC and HFC refrigerants, including R-22 at a 2 ton capacity.
