Parker LLD-052 Liquid Line Filter Dryer

The Parker LLD-052 is a liquid line filter dryer built for HVAC and refrigeration systems. It uses a 75/25 desiccant blend to remove moisture and contaminants from the refrigerant circuit. The unit handles all CFC, HCFC and HFC refrigerants. It installs with SAE flare connections sized at 1/4 inch.

4.7 inch length and 650 psi rating

This filter dryer measures 4.7 inches overall and is rated for 650 psi working pressure. It replaces older dryers that lack the 75/25 blend or the higher pressure rating. The jump is worth it when the system requires R-410A compatibility at 1 1/2 ton capacity or R-22 capacity at 3 1/2 ton. Steel construction resists corrosion in demanding environments.

Technicians servicing mixed refrigerant systems

Contractors working with both legacy and modern refrigerants will appreciate the broad compatibility. Installers needing a compact cut-out length of 4 3/4 inches benefit from the small footprint. Builders requiring larger connection sizes or higher tonnage ratings should look at alternative models. Those needing metric flare threads will need a different fitting type.

Questions about this item

Will the 1/4 in SAE flare connections on this 4.7 in filter dryer fit my existing liquid line?

The unit has 1/4 in SAE flare fittings on each end, so it connects directly to a matching 1/4 in flare liquid line without adapters.

What is the correct orientation and torque when installing the Parker LLD-052?

Install with the flow arrow pointing toward the evaporator and tighten each flare nut to the manufacturer’s specified torque for 1/4 in SAE fittings; over-tightening cracks the flare seat.

How often should the 75/25 desiccant core be replaced in an R-410A system rated at 1.5 ton?

Replace the filter dryer whenever the system is opened for service or after a compressor burnout; the 75/25 desiccant blend is not field-replaceable, so the entire 4.7 in shell is swapped out.
