Stop in for a cup of coffee

Evening all. Have a question . Had to replace idler arm on duster. Went and got a replacement. Moog K 7086 . My question is there is no rubber on the end that goes in the center link. The NOS one had it . Just wondering about water getting in. Sure is a lot different than the NOS one.
