Mitsubishi Electric e22155666 Ac Union Gas Fitting

Product Description

The Mitsubishi Electric e22155666 is a gas-side union fitting designed for use in split-system air conditioning installations. This component provides the refrigerant gas-line connection point between the indoor and outdoor units of a compatible mini-split system. The fitting is sized for 12.7mm line sets, which corresponds to the gas-side tubing used on smaller-capacity split systems. HVAC technicians install this part during new system commissioning or when a refrigerant line connection needs to be replaced or re-terminated at the indoor unit.

This union fitting is associated with the MSZ-AP22VGD indoor wall-mounted unit, indicating use in residential mini-split applications. It is typically installed as part of a complete line-set connection during system setup or service. Proper brazing or flare technique is required to maintain a leak-free refrigerant circuit. This type of fitting is handled by licensed HVAC technicians working on split-system refrigerant circuits.

Installation Notes

Installation should be performed by a licensed HVAC technician certified to handle refrigerants under applicable regulations. The refrigerant circuit must be recovered and the system depressurized before removing or replacing any refrigerant line fitting. Follow the manufacturer service documentation for proper flare or braze procedures applicable to this connection type. Ensure all connections are leak-tested after reassembly before recharging the system.
