Frequently Asked Questions

Q: Should I replace this seal every time I remove my toilet?
Yes. Old seals compress and will not reliably reseal once removed.

Q: Will this fit VacuFlush or Traveler 111?
No. It is only for 110, 210, and 510H models.

Q: Is this the genuine OEM gasket?
Yes — this is the authentic Dometic floor flange seal.

Q: My toilet rocks or smells even after cleaning. Is this the part I need?
Most likely. A worn flange seal is the #1 cause of base odors and instability.
