• Restore Vacuum PerformanceTimely replacement of worn or deformed valves helps resolve common issues such as vacuum loss, weak flushing, reduced suction, and frequent pump cycling, restoring proper operation of RV and marine toilet and vacuflush systems
• Durable Rubber ConstructionMade from high-performance rubber material with good resistance to sewage, corrosion, and aging. Maintains flexibility and sealing performance under repeated pressure cycles without cracking or deformation
