Having to install a bathtub column I need to extent the 3/8 braided flex pipes sticking out about 3" from the bottom of the column and exposing a
3/8 female connector with a flat rubber gasket around the central metal nozzle. Pretty standard, all flex pipes I see @ HomeDepot are like this.
The (potential) problem is not finding anywhere an extender 3/8 male + 3/8 female where the male connector would not be of type compression.
The problem I see with compression OD male-male adapters or 3/8 male - 3/8 female extenders is the very small contact surface between the male's connector and the rubber gasket - essentially the contact is at the outer edge of the gasket. I did a pressure test with the compression-type extender and for a few hours there were no leaks. But for how long the marginal contact with the rubber gasket will hold, especially with hot water.

Any advice greatly appreciated

This is awkward, but...
