Hello, thanks for writing in. You may connect another Manabloc to the system, however these will only work on the supply ports of the Manabloc. The ports themselves will remain 1/2".
No you can not use this adapter with the ProPex Expansion tool. For this item you would need to use a crimp tool. You cannot connect to the manablocs using the ProPex system.
Yes, it does.
It works with either copper crimp rings or stainless steel clamp rings.
No, manabloc supply thread is proprietary and not NPT.
This fitting works with any of the three supply ports on the MANABLOC. You would use it if you need to attach 3/4" PEX using a crimp connection.
