Holyoke Fittings 446-810 Flare Adapter 1/2 X 5/8 Inch Od

Product Description

The HOLYOKE FITTINGS 446-810 is a male flare to female flare adapter designed for refrigerant line connections in HVAC and refrigeration systems. This fitting transitions from a 1/2 inch OD male flare connection to a 5/8 inch OD female flare connection, allowing technicians to join or adapt tubing of two different diameters within a sealed refrigerant circuit. It is a standard-style brass fitting suited for use by licensed HVAC technicians and refrigeration mechanics working on split systems, heat pumps, and similar equipment where flare connections are specified.

This adapter is commonly used in residential and light commercial HVAC and refrigeration applications where a size transition between copper refrigerant lines is required. The male flare to female flare configuration allows direct in-line adaptation without additional fittings. It ships in a box quantity of 10 units, making it appropriate for service contractors who want to stock the fitting for recurring field use.

Key Features

• Transitions 1/2 inch OD male flare to 5/8 inch OD female flare in a single fitting
• Standard flare connection type for secure, leak-resistant refrigerant joints
• Box quantity of 10 units supports field stock for service contractors
• Compact adapter form factor reduces additional connections in the refrigerant circuit

Compatibility

Designed as an OEM-style replacement and service fitting for HVAC and refrigeration systems using 1/2 inch OD and 5/8 inch OD flare connections on copper refrigerant tubing.

Installation Notes

Installation should be performed by a licensed HVAC or refrigeration technician in accordance with applicable mechanical codes. Recover and evacuate the refrigerant circuit before disconnecting or adding any flare fittings. Hand-tighten the flare connection first, then torque with flare wrenches to avoid cross-threading or deforming the flare seat. Inspect the flare seat on both mating surfaces for nicks or debris before assembly.
