Flojet Viton Valve Kit Chamber Sub-Assembly

The Flojet Viton Valve Kit Chamber Sub-Assembly (MPN 20407021) is a precision replacement component designed for Flojet Triplex pump systems. This FKM check valve kit addresses the core hydraulic function of diaphragm pump assemblies, ensuring reliable one-way flow control and pressure management in demanding fluid transfer applications across marine, industrial, and mobile equipment contexts.

The Viton elastomer material (FKM) provides superior chemical resistance compared to standard rubber compounds, making this sub-assembly suitable for exposure to fuels, solvents, saltwater environments, and aggressive cleaning agents. The chamber sub-assembly design allows for field replacement without requiring complete pump disassembly, reducing downtime on vessels, agricultural sprayers, and industrial transfer systems. Weighing 0.5 lbs and measuring 4 x 1 x 4 inches, this compact component integrates seamlessly into existing Triplex configurations.

This replacement kit is essential for operators maintaining aging or high-cycle Flojet pump systems. Valve degradation—manifesting as reduced pressure, flow inconsistency, or leakage—signals the need for chamber sub-assembly service. Technicians, fleet managers, and equipment owners relying on consistent fluid transfer in boat wash systems, deck wash operations, chemical spraying, and pressure cleaning benefit from OEM-specification replacement parts that restore pump performance to manufacturer standards.

Flojet pumps are widely deployed in marine, RV, and agricultural sectors where reliability under intermittent heavy use is non-negotiable. Genuine Flojet sub-assemblies like this Viton valve kit chamber ensure compatibility, longevity, and regulatory compliance for systems operating under variable pressure and temperature conditions.
