Product Description

The MITSUBISHI ELECTRIC adp3812 is a multi-zone port adapter designed to facilitate refrigerant line connections in multi-zone mini-split and VRF system installations. This adapter provides a transition between differing port sizes, allowing technicians to properly interface refrigerant circuits where connection geometry would otherwise be incompatible. The adp3812 fits into the broader Mitsubishi Electric accessory lineup as a field-installed component used during system commissioning or servicing. Licensed HVAC technicians and refrigeration mechanics are the primary installers of this type of adapter in both residential and light commercial applications.
