Holyoke Fittings 46-84 Brass Straight Adapter 1/2 Flare X 1/4 Fpt

Product Description

The HOLYOKE FITTINGS 46-84 is a brass straight adapter designed to transition a 1/2 inch SAE flare connection to a 1/4 inch female pipe thread. This fitting is used in refrigeration, HVAC, and plumbing systems where a direct inline connection between a flare tube and a female-threaded port is required. Brass construction provides reliable corrosion resistance and durability in both gas and liquid service applications. Licensed HVAC technicians and plumbers install this adapter during line set connections, appliance hookups, and service work where mismatched connection types must be joined without additional fittings.

This adapter is suited for residential and light commercial applications involving refrigerant lines, fuel gas piping, and similar systems that use SAE flare fittings on one side and female pipe threads on the other. It is sold in quantities of 25 per bag, box, or carton, making it practical for service vans and shop stock. The straight configuration keeps the connection inline and minimizes added length in tight installations.

Installation Notes

This fitting is typically installed by licensed HVAC technicians or plumbers. Shut off all gas or refrigerant supply and depressurize the line before disassembly or installation. Apply thread sealant appropriate for the service medium to the female pipe threads before assembly. Tighten to snug plus a controlled additional turn — do not overtighten brass fittings, as brass threads can be damaged by excessive force.
