So far, Vevor products have been pretty solid. This is no different. Much like the other imported manifolds available on Amazon, this unit has standard metric connections for the pex adapters, and the actuating valve connections - if you plan to add any accessories, keep that in mind. It does include everything you need to run it as is, as long as you have a pipe in each hole and don’t want the electronically controlled actuator valves. The specific valve connections to your system are standard NPT. High quality manifold body, and the unit arrived with excellent packaging. Bought this for an additional manifold in a 16 port system. I do recommend this manifold. Standard compression fittings for the 1/2” pex. One thing I wish they would offer is a booklet that specifically pointed users to the correct connections for caps, actuators, and parts.
