Need name of a LWCO fitting

Options
Can someone tell me the name of an iron fitting sort of shaped like a ball or two cones with a water line marked on it to mount a probe LWCO external to a boiler?

Someone posted one here on an install they made, and for the life of me I can't remember what the darn thing is called.

Thanks!

    I recently installed a SafGard LWCO. Those special tees can be seen in these instructions. Hope this helps. https://s3.amazonaws.com/s3.supplyhouse.com/product_files/Hydrolevel-45-170-Install-Instructions.pdf

    I am in the process of upgrading my controls, and I will no longer be needing my LWCO, since this function is built in. I will sell it cheap if you need it. And I added a combo buzzer/flashing LED to it. It's the bright blue box in this pic.
