No, you just slide the fitting on and crimp it with the tool, takes maybe 10-15 seconds to make the crimp. We use it when replacing water heaters so we don't have to wait for the whole house to drain down to replace a ball valve, you can slide a valve on with water pouring out of the pipe, crimp it and turn the valve off.
You will want to verify what fittings will work with that pipe but it shouldn't be very tough to find out.
