Thetford Lipseal for C2/C3/C4/C200/C250 Cassette Toilets (23721)

Thetford Lipseal for C2/C3/C4/C200/C250 Cassette Toilets (23721)

Genuine Thetford lipseal for C2, C3, C4, C200, and C250 cassette toilet models. The lipseal is the rubber seal between the toilet bowl and the cassette — it prevents odours from escaping and ensures a hygienic, airtight connection between the two components. Over time, lipseals can deteriorate, dry out, or become damaged, leading to odour problems or sealing failures. This is a direct replacement to restore full seal performance.

Key Features

• Genuine Thetford lipseal replacement — for C2, C3, C4, C200, and C250 cassette toilet models
• Creates an airtight seal between the toilet bowl and cassette
• Prevents odours from escaping through the cassette connection
• Replaces deteriorated, cracked, or damaged lipseals
• Essential maintenance part for reliable, odour-free toilet operation

When to Replace

The lipseal should be replaced if you notice persistent odours from the toilet, if the seal appears cracked or deformed, or as part of a routine maintenance service. Thetford recommends regular lubrication with a blade lubricant to extend lipseal life.
