It is possible to remove and install the air conditioning unit while keeping the refrigerant gas charged. The connection of the refrigerant piping is easy and quick.

The "Nas Union MV Type" is a copper pipe fitting equipped with a special opening and closing valve at the socket and plug section, which prevents gas leakage from the equipment even when the fitting is removed. During the relocation or maintenance of air conditioning units, it allows for piping connections while keeping the refrigerant gas charged. To connect the fitting body, secure the plug body and tighten the flare nut on the socket side to the specified torque until it contacts the end of the plug, and the connection is complete. 【Features】 ■ Easy connection, reducing installation burden ■ Excellent valve sealing performance ■ Operating temperature range: -30°C to 120°C *For more details, please refer to the documentation. Feel free to contact us with any inquiries.
