Dometic Sealand Duckbill 1 1/2″ Valves – Pair

If worn or damaged duckbill valves have created a loss of vacuum integrity in a VacuFlush toilet system, or if a duckbill valve has become inverted due to pumping out against a closed seacock, depend on original SeaLand duckbill valves to make the system work like new. Two sizes fit all SeaLand J series vacuum generators, S series vacuum pumps, M series vacuum pumps, and T series discharge pumps.
