1 Person needs an answerI have this question too


It would depend on what size access ports your mini split system is equipped with, some have standard 1/4" connections, and some have 5/16" connections. These manifolds have 1/4" connectors and would require an adapter if you had the 5/16". The adapter would be item number 3DXH4.
