The Teflon seat provides a durable, chemical-resistant sealing surface, while the O-rings (Tef-O-Sil, Teflon-encapsulated silicone) ensure a tight seal and prevent leaks. You would replace this seat when the existing one is worn, cracked, or causing valve leakage, typically as part of routine valve maintenance or overhaul.
