Isotope Core Accessory Kit

This is the exact same set of accessory parts included with our Isotope Core fob. If you ever lose the tiny rubber plugs, damage an o-ring when changing out a tritium vial or scratch the tritium cell, we have you covered. Refer to the diagram for installation instructions. NOTE: You can also use this kit to upgrade our TEC-T9 Glow Fob to the Isotope Core, by replacing the Embrite™ glow pellet with your own tritium vials installed into this kit. What you get: (4) Rubber Plugs: 3 Required plus 1 spare (1) O-Ring (1) Neoprene washer (1) Resin tritium cell
