The tube includes an opening and an impingement site located opposite the opening. The bushing includes an opening aligned with the opening of the tube, and an end plate. The bushing assembly is readily removed and inserted into the shot sleeve such that the openings of the bushing assembly align with the pouring hole of the shot sleeve. A method of replacing an impingement site of a shot sleeve with an erosion resistant material is also disclosed.
