Ndl Industries NMH-165S Liquid Line Filter Drier 5/8 in Ods

Product Description

The NDL INDUSTRIES NMH-165S is a liquid line filter drier designed for use in refrigeration and air conditioning systems. Installed on the liquid line between the condenser and the metering device, this filter drier removes moisture, acid, and particulate contamination from the refrigerant circuit. It features a 5/8 inch ODS (Outside Diameter Solder) connection, making it compatible with standard copper line installations. Licensed HVAC technicians install this component as part of routine system service or following compressor replacement to protect downstream components from debris and moisture-related damage.

This filter drier is suited for residential and light commercial refrigerant systems where liquid line protection is required. It is typically installed during system commissioning, after a compressor burnout cleanup, or whenever the refrigerant circuit has been opened and exposed to atmosphere. The ODS connection style allows for a secure, brazed-in-place installation on copper refrigerant tubing.

Key Features

• 5/8 inch ODS connection for brazed copper line installation
• Liquid line configuration removes moisture, acid, and solid contaminants from the refrigerant stream
• Designed for installation between condenser outlet and metering device
• Suitable for use following compressor replacement or burnout remediation

Compatibility

Designed as an OEM-style replacement or new-installation liquid line filter drier for refrigeration and air conditioning systems using 5/8 inch ODS copper liquid line connections.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with applicable refrigerant handling regulations, including EPA Section 608 requirements. Recover all refrigerant from the system before cutting or unbrazing any line connections. Use nitrogen purge and proper brazing technique when sweating the ODS fittings to prevent oxidation scale inside the refrigerant circuit. Ensure the drier is installed with flow direction matching the arrow or label indicator on the drier body.
