Thetford Toilet Lip/Blade Seal | OEM Replacement Seal

The lip/blade seal is what keeps water and waste properly contained between flushes, and like any wear part, it eventually loses its seal and needs replacing. This Thetford part is the correct OEM-style fit for restoring that seal on compatible toilet models.

A worn seal usually shows up as a slow leak at the base of the bowl or a flush that doesn't hold water the way it used to — both signs it's time for a swap rather than a workaround.

• Direct-fit lip/blade seal for compatible Thetford toilets
• Restores proper flush and water-hold seal
• Durable plastic construction
• Straightforward replacement part for routine maintenance

A simple, inexpensive fix that keeps your RV toilet sealing and flushing the way it should.
