Need Help Finding a Gasket

[curt5446]

I was doing my oil pan gasket and trying to find all of my oil leaks so I can get them mended and found that I have a leak from the plate on the back of the oil filter housing. This is the plate that the turbo receives its oil supply from as well as where the oil pressure gauge. I temporarily "fixed" it with some gasket maker till I can find the correct gasket.

Any information on what the gasket is called would be appreciated.
