Parker SLD-8-4SV-HH filter-dryer

The Parker SLD-8-4SV-HH is a liquid line filter-dryer built for automotive HVAC and stationary refrigeration systems. It fits lines requiring a 1/2 inch solder connection and handles all CFC, HCFC and HFC refrigerants. Installers working with R-22 or R-410A will find the rated capacities match common tonnage requirements. It is not for systems needing larger connection sizes or different fitting types.

High acid capacity under continuous flow

The desiccant core maintains high acid removal capacity while refrigerant circulates under sustained load. Inlet and outlet access valves allow pressure checks without breaking the circuit during long service intervals. The unit supports R-22 capacity of 2 1/2 ton and R-410A capacity of 3 ton throughout the operating cycle. It does not suit applications exceeding these refrigerant tonnage ratings.

Compact body for tight service access

Overall length measures 4 7/16 in with a cut-out length of 3 1/8 in, letting the assembly sit in confined equipment compartments. Solder connections create a permanent, leak-resistant joint once brazed in place. No moving parts mean zero vibration noise and no electrical power draw. The design omits a sight glass, so moisture indication requires a separate device.

Questions about this item

How much heat does the SLD-8-4SV-HH generate when running continuously?

The filter dryer is a passive component with no moving parts, so it produces no measurable heat during all-day operation.

What refrigerant lines and valves must already be in place for the SLD-8-4SV-HH to work?

You need a 1/2-inch solder connection line set and compatible access valves for the inlet and outlet ports.

Will the SLD-8-4SV-HH work with an older R-22 system rated at 2 1/2 tons?

Yes, it is rated for R-22 at 2 1/2 tons and also supports R-410A up to 3 tons.
