Holyoke Fittings 46-106 Female Flare Adapter 5/8 X 3/8

Product Description

The HOLYOKE FITTINGS 46-106 is a female flare adapter designed to connect refrigerant or fluid lines with differing tube sizes. It steps down from a 5/8-inch female flare connection to a 3/8-inch fitting, allowing technicians to join mismatched line sizes in HVAC, refrigeration, and related mechanical systems. This type of reducer adapter is a standard component in service and installation work where tubing diameters must be transitioned without losing a leak-free flare seal. HVAC technicians and refrigeration mechanics are the primary installers of this fitting.

The 46-106 adapter is suited for residential and light commercial HVAC and refrigeration applications where 5/8-inch and 3/8-inch flare connections must be joined. It is appropriate for use in refrigerant line sets, copper tubing assemblies, and similar fluid-handling systems that use flare-type fittings. This adapter is typically installed during system assembly, line set modification, or service work requiring a size transition at a flare connection point.

Key Features

• Female flare inlet at 5/8 inches for secure, leak-resistant connection
• 3/8-inch outlet for transitioning to smaller-diameter tubing or fittings
• Reducer configuration allows mismatched line sizes to be joined cleanly
• Flare-type design provides a reliable, tool-tightened mechanical seal

Compatibility

Designed as a standard female flare reducer adapter for use in HVAC, refrigeration, and mechanical systems that utilize 5/8-inch and 3/8-inch flare-type connections.

Installation Notes

Installation should be performed by a licensed HVAC technician or refrigeration mechanic familiar with flare fittings and refrigerant-handling regulations. Recover any refrigerant and depressurize the system before removing or installing fittings. Use appropriate flare wrenches to tighten connections to avoid cross-threading or damage to the flare seat. All refrigerant work must comply with applicable EPA and local code requirements.
