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

The "Nasunion MV Type" is a copper pipe fitting equipped with a special opening and closing valve at the socket and plug section, preventing gas leakage from the equipment even when the fitting is removed. It allows for piping connections while keeping the refrigerant gas charged, even during the relocation or maintenance of air conditioning units. To connect the fitting body, secure the plug body, tighten the flare nut on the socket side to the specified torque, and continue tightening until it contacts the end of the plug. 【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.
