      Nylon Flange for S3 fuel or water sender / S3H holding tank (black water) sender.

      Fitted to topside of tank to create 1 ¼" BSP thread.  

      The FL-3 can be used, if you don’t need the under-ring FL-U or FLS-U. It has larger screw holes, so larger screws can be used, if needed.

      This flange is used to mount the S3 sensor in the tank. A nitrile rubber gasket is included.


      For mounting in tanks with a thin top it is recommended to use an HFL flange or FL-2 flange together with a FL-U under-ring or FLS-U to secure against leaks.  The FL-2 has a standard SAE-5-hole pattern.
