Variation A: 1-1/2″ duckbill valves
Variation B: 2″ duckbill valves
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.
- Replaces duckbill valves in J series vacuum generators and M series vacuum pumps
- Includes two valves per kit; four valves are required for vacuum pump
- Maintains vacuum integrity in VacuFlush toilet systems
- Provides backflow protection in discharge pump operation
