These o-rings fit the original hydraulic couplers on John Deere 425 445 455 X465 X475 X485 X495 X585 X595 X700 X720 X724 X728 X729 X740 X744 X748 Garden Tractors, all years.

If your coupler leaks while your implement is connected, you may only need to replace the o-ring. Why buy a new set of couplers when only the o-rings are leaking.

These O-Rings are the correct hydraulic grade V90 Black Viton.
