A brass charging nipple is a short, threaded piece of brass pipe used as a fitting to connect pipes or other components, often in applications like refrigeration or HVAC systems. It's primarily used for gas charging and service connections. Brass is chosen for its durability, corrosion resistance, and conductivity.

A brass charging nipple is a short, threaded brass pipe used to connect to a gas pipe, typically for air conditioning or refrigeration systems. It's designed to facilitate the process of adding refrigerant (or gas) to a system, such as an AC or refrigeration unit, by providing a secure connection between the charging gauge and the system's service port. The brass material offers good conductivity and durability.                                                                                                                                               .
