Good Morning, My question is regarding parts for my Thetford toilet cassette. I need to replace the main seal and the vent seal. The toilet came with my caravan and I presume is original. My caravan is 22 years old & we've had some great times with it in the past 5 years. The details on the label under the cassette is as follows: Model - Cassette PP C2 R No. 1631810 GO6 0033 Code: 910527 Could you please advise me which parts I need to order and their price. Many thanks, Colin

Seal

Does as it says easy to replace. If your sliding lid keeps falling of this will help it stay on. If it’s leaking this will stop it (proving it’s leaking from this seal and you for it correct) Use gloves and give good rinse out first.
Used this on old caravan.
