Where to find a Korallin compression nut?

[CuseReefer84]

As the title says does anyone know where I can find one of these nuts? I think its called a compression fitting or nut and its for my Korallin Calcium Reactor. I've searched everywhere that I could think of Ebay, Google, Amazon, BRS, Marine Depot and I can not find one anywhere. Any advice is greatly appreciated.

That nut is part of the inlet or outlet assembly of the reactor. You would probably need to buy one of the arms. Marine depot sells them. Another idea would be to contact korallin and ask them (if the're still around).
