Port Adapter - 5/8 x 3/4 Female Flare x Flare Adapter w/ Copper Gasket

This port adapter allows you to connect a 3/4" line set to a 5/8" port on a branch box or distribution pipe when installing a multi-zone mini split system. The adapter is installed at the branch box or distribution pipe so that you can use a line set that matches the diameter of the outdoor unit. The UR3-1012 adapter has flare fittings for an easy installation.

Please note that you will need to make the reduction at the branch box or tee, not at the outdoor unit, before running the 3/4 inch refrigerant line from the outdoor unit.
