Frequently Asked Questions

Q: Should the flange seal be replaced every time I remove the toilet?
Yes — old seals compress and won’t reseal properly after removal.

Q: Will this kit work with Bravura or Aqua-Magic IV?
No. This kit is only for Style Plus, Style Lite, V, and VI toilets.

Q: Is this a genuine Thetford part?
Yes — 28971 is the official OEM bolt and seal kit.

Q: What’s the difference between 28971 and 28972?

• 28971 = White flange seal

• 28972 = Parchment (off-white/beige) flange seal
  Hardware is the same; only the color differs.

Q: Can this be installed by an RV owner without a technician?
Yes — installation is straightforward and requires only basic tools.
