Can the Carbon Steel A/C Quick Connector Plug with Valve, UNF Male Thread be disconnected under full working pressure without refrigerant loss?

Yes. The Carbon Steel A/C Quick Connector Plug with Valve, UNF Male Thread is engineered to be disconnected even at maximum working pressure without refrigerant loss. Its integrated shut-off valve and design explicitly allow tightening under residual pressure and safe disconnection at full working pressure. The durable galvanized carbon steel body, CR chloroprene rubber sealing (operational −40°C to +120°C), and robust safety factors (3:1 static, 2:1 dynamic) ensure secure operation. The plug also minimizes refrigerant emissions (only 1.5 g per year) and supports a maximum vacuum of 2 mm Hg, providing both operational convenience and environmental protection.

Does the Carbon Steel A/C Quick Connector Plug with Valve, UNF Male Thread allow tightening or disconnection under residual or full working pressure without compromising safety?

Yes. The Carbon Steel A/C Quick Connector Plug with Valve, UNF Male Thread is engineered to allow tightening under residual pressure and safe disconnection even at maximum working pressure. Its integrated shut-off valve, robust galvanized carbon steel construction, and CR chloroprene rubber seal provide secure operation across -40°C to +120°C. The design minimizes refrigerant loss (1.5 g/year), supports a maximum vacuum of 2 mm Hg, and includes safety factors of 3:1 (static) and 2:1 (dynamic), ensuring reliable and safe use in demanding HVAC and refrigeration conditions.
