So this Teflon ring, it's just for keeping seals from squishing out under pressure, right?

That's right. This back-up ring is designed to prevent seal extrusion in hydraulic systems, especially when the pressure gets high. By supporting the seal, it helps to maintain system integrity and extends the seal's life.
