Mitsubishi PAC-MKA52BC Branch Box - 5 Ports For MXZ C Series Heat Pump Systems

So, this is the brains of the operation for a Mitsubishi ductless mini split system.

It's a genuine Mitsubishi branch box, model PAC-MKA52BC, from their M-Series and MXZ C Generation.

It's a 5-port unit, meaning it can handle multiple indoor units.

This one is brand new, still in its original packaging.

It's designed to work with a bunch of different MXZ outdoor models, like the MXZ-8C48NAHZ and MXZ-SM36NAM, just to name a couple.

The specs are pretty specific: the liquid lines are all 1/4\, while the suction lines are four 3/8\ and one 1/2\.

It uses flare valves and its dimensions are about 17-3/4\ wide, 11\ deep, and 6-11/16\ tall.

Weighs in at 16 lbs.

As with many HVAC parts, there's a California Prop 65 warning.
