Totaline p504-h163p Press Fit Filter Drier 16 Cu 3/8 in

Product Description

The TOTALINE p504-h163p is a press fit liquid line bi-flo filter drier rated at 16 cubic inches with 3/8-inch press fit connections on both the inlet and outlet. Designed for use in refrigerant circuits, it removes moisture, acid, and contaminants from the liquid line to protect compressors, expansion devices, and other system components. The bi-flo design allows bidirectional flow, making it compatible with heat pump systems that reverse refrigerant direction during heating and cooling cycles. Licensed HVAC technicians install this drier as part of routine service or after a system repair involving an open refrigerant circuit.

This filter drier is suited for residential and light commercial refrigerant systems using R-32 or R-454B refrigerants. It is installed in the liquid line between the condenser and the metering device. The press fit connection style simplifies installation without the need for brazing, reducing labor time and heat-related risk to nearby components. Systems requiring a compact, bidirectional drier with a 3/8-inch line size are the primary application.

Key Features

• Bi-flo design supports bidirectional refrigerant flow for heat pump compatibility
• Press fit connections on both inlet and outlet eliminate brazing requirements
• 16 cubic inch capacity provides solid moisture and acid removal capacity for residential systems
• Compatible with R-32 and R-454B next-generation low-GWP refrigerants
• 3/8-inch inlet and outlet sizing fits common residential liquid line configurations
• Manufactured in Mexico to TOTALINE specifications

Compatibility

Rated for use with R-32 and R-454B refrigerants. Designed as an OEM-style liquid line filter drier replacement for residential and light commercial heat pump and air conditioning systems using 3/8-inch press fit liquid line connections.

Installation Notes

Installation must be performed by an EPA Section 608 certified HVAC technician. Always recover refrigerant and confirm the system is fully depressurized before opening the refrigerant circuit. Install with the flow arrow aligned to the intended refrigerant flow direction; for bi-flo applications in heat pump systems, either orientation is acceptable per manufacturer design. Replace the filter drier any time the system has been open to atmosphere or after a compressor burnout.
