Jabsco Top Valve Gasket for Manual Toilets 29090 & 29120

Description

The Jabsco Top Valve Gasket 29042-0000 for Manual Toilets series 29090 & 29120 is a precision replacement seal used in the top valve assembly of Jabsco manual marine toilets. This gasket provides a secure, watertight seal that maintains proper vacuum and discharge control during each pump cycle. Manufactured from durable, marine-grade elastomer, it is resistant to saltwater, waste, and routine sanitation chemicals. Replacing the top valve gasket during regular servicing helps prevent backflow, loss of pumping efficiency, and internal leakage within the toilet pump assembly.
