Also worth having before you start

  • Disposable nitrile gloves

    General guidance for any waste-contact job, not specific to one manufacturer: wear protective gloves and eye protection when you touch anything that has been in contact with human waste, and disinfect your tools and work surface afterwards. If you do not already have a box in the camper, get one 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 Campa Potti, Campa Potti MT, Porta Potti 155 / 155SL / 135 / 135 Marine, Porta Potti 235 / 245 / 255 / 265, Porta Potti 260 / 335, Porta Potti 345 / Campa Potti XG, Porta Potti 365 MSD / 365, Porta Potti 465 / 465 MSD, Porta Potti 555 / 565 / 735 / 735 Marine, Porta Potti 735 MSD / 735 Marine / 775 MSD or Porta Potti Curve 550E / 565E.
  • Ignore listing titles that claim one part covers several models unless the manufacturer's parts lists agree.
