STC® fittings are used on steel lines, hose connections and come in a variety of sizes. JDG1885 STC® tool (A) is designed as a spacer to move release ring (B) inward which releases retaining ring (C). Purchase tool from your John Deere dealer.

  1. Do not use tool to pry fittings apart. Prying with tool may damage fitting and tool.

    If retaining ring, backup ring (F) or O-ring (E) are damaged, see your John Deere dealer for replacement kit and replace all three parts.

    Insert correct STC® tool between release ring and fitting.

  2. Remove hose or line from connector.

  3. Before connecting STC® fitting, check mating surfaces for nicks, scratches or flat spots.

  4. Check O-ring, backup ring and retaining ring for wear or damage.

  5. Check that female end (D) and male end (G) are clean and free of contaminates.

  6. Place release ring on male end fitting.
