How do I connect my rubber to the plunger for a syringe assembly in Creo Parametric? Please help. Its urgent...

I have an assignment where I have to connect my rubber to the plunger in assembly. I get the axis alignment right, but I get the other part wrong. I would be grateful if anyone can help. Thank you.

first of all you select axis what you want to align then you select face what you want to coincident

You must constrain these two surfaces together
