Hydraulic pistons with 45 degree o-ring seat

[Lanza]

Photo attached of a hydraulic rod with a 45-degree seat that matches the angle on the piston bore. The o-ring fits in the groove, I know some of you would have come across this style before. I was wondering if specifications chart exist for the groove depth.
Looking at the https://www.parker.com/Literature/O-Ring Division Literature/ORD 5700.pdf page 4-21 on triangular grooves for o-rings, I will see if this information is close to what I have.

I had another look at it, it appears to be about 37.5 degrees measuring it with a protractor.

Did you check SAE O-ring port specs? It uses a 45 degree O-ring gland.

You mean the table with dimensions for L right there on page 4-21? Or are you asking about an ASME/ANSI/ISO/JIS numbered spec document, rather than this info from Parker?

Yes the depth L on page 4-21. I will work out the depth minus the 3/64" radius.
