Difference between an internal and external o-ring groove

[Baraa Karam]

Is there a difference between an internal o-ring groove/gland sealing and external o-ring groove/gland sealing?
Whether from performance or installation wise? or any other.

Reference the Parker Oring Handbook.

I did a search in the handbook, but didn't find what I'm looking for.
can you refer to the section or page?

Look at section 4, static seals.
An internal or female gland tends to put a slight compression fit to the oring OD to keep it in place during assembly.
An external or male gland tends to slightly stretch the oring ID to keep it in place during assembly.
