Also worth having before you start

  • Thetford seal lube and conditioner

    A new seal lasts longer if it is kept conditioned. Thetford makes this for its own toilets, so it is the maintenance product matched to the part you are fitting.

These are supplies, not replacement parts. We have not matched them to your model, because they do not need to fit anything.

Check this before you order

  • Confirm your toilet is a Aqua-Magic Style Lite or a Aqua-Magic Style Plus.
  • Ignore listing titles that claim one part covers several models unless the manufacturer's parts lists agree.
