R410 Refrigerant Charging Valve 5/16" Male To 5/16" Female Adapter, Red

This air conditioner flow control valve adapter is made of high-density brass, offering a stable structure, high strength, high pressure resistance, corrosion resistance, and excellent sealing performance. The lightweight aluminum knob is easy to rotate, non-slip, wear-resistant, and rust-proof. Its integrated seal stays tight during connection, pressure holding and disassembly. Equipped with a ball valve flow control structure, the adjustable control valve adapter greatly improves flow stability and regulation accuracy. The knob enables stepless precise adjustment. Counterclockwise rotation cuts off pressure while clockwise rotation connects pressure for smooth and refined control over refrigerant flow volume. The refrigerant safety valve serves as a professional safety tool customized for AC maintenance work including refrigerant charging, pressure testing and refrigerant recovery. It fits maintenance and repair of refrigerant used in all household and commercial air conditioners. Installation is simple: it only needs to be installed at the end of the charging hose to minimize refrigerant loss during maintenance. Please connect according to the specified specifications and never force the adapter onto any non-standard threaded ports. Do not screw it in diagonally by force to prevent thread stripping or breakage, which may damage the adapter and equipment ports.
