Here you go. Order this. You will receive a Viton O-ring, to replace your worn-out or leaking one. Note: O-Rings have been upgraded from Buna Nitrile to Viton. Viton is more durable & longer lasting.
We also include original kit installation instructions with the replacement O-Rings.
Unfortunately, the postage to ship them is sometimes more than the cost of the O-Rings themselves.
