The Thetford Cassette Bellows slots into compatible cassette toilets and gets the flushing setup working again on any unit except the 230 and 240 models. The plastic bellows connects straight onto the waste cassette section so you can tackle everyday use on trips where the caravan sits 1–2 m off the ground on levelling gear. The white finish makes it simple to spot wear when you slide the cassette out around every 2–3 days.

The plastic construction keeps the bellows light so the full cassette usually stays under roughly 15 kg when loaded. The smooth outer surface handles typical van bathroom temperatures between about 5°C and 40°C without cracking. The compact body fits through side access doors commonly 30–40 cm wide so you do not have to fight for space in the service hatch. Straightforward sealing points make it a smart buy as a spare in any Thetford cassette kit.

Q: Does this bellows fit Thetford 230 or 240 cassette toilets?

No, this bellows does not fit Thetford 230 or 240 cassette toilet models. It is only suitable for other Thetford cassette models. If your toilet plate lists 230 or 240, this is not the right gear. Check the model label on the toilet or cassette before ordering.

Q: Is this a complete cassette toilet or just a spare part?

This is just the cassette bellows spare part. It replaces the original bellows unit inside a compatible Thetford waste cassette. The rest of the toilet, cassette tank and plumbing hardware are not included. Use it when the existing bellows is worn, cracked or no longer pumping properly.

Q: What colour is the Thetford Cassette Bellows?

The Thetford Cassette Bellows is white. The colour matches standard Thetford cassette toilet fittings commonly found in caravan and RV bathrooms. The white finish makes it easier to see dirt or wear during maintenance. This helps you spot issues early before a trip.

Q: What material is the Thetford Cassette Bellows made from?

The Thetford Cassette Bellows is made from plastic. The plastic construction keeps overall cassette weight down in a caravan or RV setup. It also allows the bellows to flex repeatedly during use. This makes it a practical spare part to carry in your setup box.

Suits all Thetford cassette toilet models except the 230 and 240 series. Fitment applies to compatible caravan and RV cassette toilets that use a Thetford waste cassette. Install the bellows in place of the original bellows assembly on the cassette unit following the toilet manufacturer’s instructions.
