Holyoke Fittings 446-84 Male Flare Female Flare Adapter

Product Description

The HOLYOKE FITTINGS 446-84 is a male flare to female flare adapter designed to connect refrigerant or gas lines of two different outside diameters. The larger end is a 1/2 inch OD male flare connection and the smaller end is a 1/4 inch OD female flare connection. This fitting allows a technician to transition between line sizes within the same flare-type system without additional couplings. It is a standard component used in HVAC, refrigeration, and gas distribution work where flare fittings are required by code or system design.

This adapter is suited for residential and light commercial HVAC and refrigeration systems where a size reduction or step-down is needed between flare-connected components. Typical applications include service work on refrigerant circuits, charging port adapters, and gas line assemblies where a 1/2 inch OD male flare must mate with a 1/4 inch OD female flare port. Licensed HVAC technicians and refrigeration mechanics are the primary installers of this fitting type.

Key Features

• 1/2 inch OD male flare inlet transitions to 1/4 inch OD female flare outlet
• Flare-to-flare design requires no solder or brazing for assembly
• Compatible with standard 45-degree SAE flare tooling
• Compact adapter profile minimizes added length in tight installations

Compatibility

Designed as an OEM-style replacement or service fitting for HVAC and refrigeration systems using SAE 45-degree male and female flare connections in 1/2 inch and 1/4 inch OD line sizes.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified tradesperson. Recover or isolate refrigerant and shut off gas supply before disconnecting any flare fitting. Inspect flare seats on both mating connections for damage or debris before assembly. Hand-tighten the fitting first, then snug with a flare wrench to avoid cross-threading or over-torquing the seats.
