Charging Nipple"

These high-quality Copper Charging Access Valves (also known as service ports or Schrader valves) are essential for any refrigeration or air conditioning system. They provide a permanent, leak-proof access point for charging refrigerant, performing vacuum evacuations, and monitoring system pressures. Each valve is constructed from durable, corrosion-resistant brass with a high-purity copper stem, designed specifically for easy brazing into suction or liquid lines.
