I disassembled my AEA Element because of a leak in the fill port. Very easy to take apart, but was surprised to find the sealing rings to be square bodied instead of the usual round I am accustomed to. Is it possible that these rings are meant to be square. Has anyone else seen this?
High pressure "O" rings

Very unusual for square cross-section O-rings to be used in a PCP airgun. More likely that it is the result of compression set.
Can you detect a little curvature on one facet with the aid of magnification?

@jland48 If you can post a close-up photo or two of the o-rings you’re describing that would help us to better understand what you’ve encountered. It can also help you to obtain better feedback. Like @nervoustrig suggests compression set is what you’re probably dealing with.

Yup, some o-rings will extrude into the square grooves and then harden / plasticize themself hard and square looking.
It was Round o-rings from the factory
They will be METRIC sizes, and once known purchase Buna/N 70 duro to replace them.

Are
"X" rings have four sealing surfaces, NOT just one like with an "o-ring".
I've used "X" ringe in my pump pistols, like my HW45, and my P1 (similar to the HW45) with great results.

Are you sure that they aren't "X" rings.

The rings that came out of the gun were square in shape and badly decomposing (brittle), but I ordered some from The Pellet Shop and they appear to be round like regular o rings. I am puzzled. I even looked at them with a strong magnifying glass and they are just round. There was some oil in the area of the rings which may account for their condition. Thanks for the responses.
