Parker Liquid Line Filter Dryer HVAC Control
The Parker SLD-27-7SV-HH is a liquid line filter dryer designed for HVAC and refrigeration systems. It handles R-22 capacities up to 10 ton and R-410A capacities up to 12 ton. The unit suits technicians who need high acid capacity filtration with integrated access valves for pressure monitoring during service work.
355 psi rated filter dryer thermals and pressure
The component withstands a maximum working pressure of 355 psi during normal system operation. Its solid copper solder connections ensure reliable sealing under thermal cycling conditions. The high acid capacity desiccant core maintains refrigerant purity without adding measurable pressure drop across the liquid line.
Inlet outlet access valves and solder connections
Factory-fitted inlet and outlet access valves allow direct pressure readings without additional service ports. The 7/8 inch solder connections suit standard copper tubing installations with a 5 1/2 inch cut-out length. The dryer supports all CFC, HCFC and HFC refrigerants, eliminating the need for refrigerant-specific inventory.

Questions about this item
How do I install the Parker SLD-27-7SV-HH filter dryer with its 7/8 inch solder connections?
Braze the 7/8 inch solder connections using a nitrogen purge to prevent oxidation, then evacuate the system before charging; the step often missed is skipping the purge, which leaves oxide scale inside the line.
What maintenance or replacement will this filter dryer need later?
Replace the filter dryer whenever the system is opened for repair, after a compressor burnout, or if a pressure drop across the core indicates saturation; the high acid capacity core cannot be cleaned or regenerated.
What limit appears first on this filter dryer during sustained high-pressure operation?
The 355 psi maximum working pressure is the first limit; exceeding it risks shell rupture, so ensure the system relief valve is set below this rating.
