Copper Charging Access Valve – 1/4″ SAE Flare with 4-Inch Copper Stem
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.

Copper Charging Access Valve – 1/4″ SAE Flare with 4-Inch Copper Stem
The 3/8″ Copper Access Valve is a high-flow service port designed for larger refrigeration systems and commercial HVAC applications. Featuring a larger 3/8″ SAE Flare connection, this valve allows for significantly faster vacuum pull-downs and refrigerant charging compared to standard 1/4″ valves. The 4-inch high-purity copper stem provides ample space for secure brazing into suction lines or large evaporator coils, making it an essential component for heavy-duty cooling maintenance.

Copper Charging Access Valve – 3/16″ SAE Flare with 4-Inch Copper Stem
The 3/16″ Copper Access Valve is a specialized service port designed for precision refrigeration systems. Often used where space is limited or on smaller-diameter tubing, this valve provides a permanent, leak-proof point for charging refrigerant, measuring pressures, or performing vacuum evacuations. Constructed with a high-purity copper stem and a robust brass head, it is engineered to be brazed directly into capillary lines or small domestic cooling circuits.

Copper Charging Access Valve – 5/16″ SAE Flare with 4-Inch Copper Stem
The 5/16″ Copper Access Valve is a heavy-duty service port designed for larger domestic systems and modern high-pressure inverter air conditioners. As many newer R410A and R32 units utilize 5/16″ service ports or tubing, this valve provides a critical, leak-proof access point for charging refrigerant, monitoring system health, and performing essential maintenance. Each valve features a high-purity copper stem for reliable brazing and a forged brass head to withstand frequent manifold connections.
