what clear plastic to use?
(OP)
I need a clear plastic that can withstand 120 deg Celsius. It cannot turn yellow or fog when exposed to heat. It will be submersed in oil on one side and will need to withstand a at least 50 PSI.
I am going to be machining or molding it, whatever is easiest.
Does anyone have any suggestion on what clear (transparent) plastic to use?

Polysulphone.
Maybe aromatic nylon.
Maybe cast acrylic.
Glass.

From the list suggested by Pat, I would pick out amorphous nylon - e.g. Grilon by EMS - used for transparent oil/water filter bowls for airline filters. (Nylon 12?)
Have a look on their website...

That temp is getting marginal, without stress. 50 psi could mean anything re stress, depending on part design.
Also, I would need to do a major properties search to be sure.
Adamijt can sift through data himself.
Nylon 12 is not all that transparent, and is very marginal at those temps.
Cast acrylic is also very marginal, but very easy to get, cheap and easy to work.
Polycarbonate (Lexan) won't take the oil.
Polysulphone should do it real easy and TPX will also have some in reserve, but the price and availability?
