Pneumercator S4K2 4" 316SS Diesel/Water Float Kit, End Cap, Cathodic Boot is a four-inch stainless steel float assembly designed for use with compatible Pneumercator probes to detect diesel product level and water accumulation at the bottom of a storage tank.

4" 316 Stainless Steel Diesel/Water Float: The kit uses a 4" diameter 316 stainless steel float configured for diesel service, allowing the float to ride on the diesel surface while responding to water that collects beneath the fuel layer.

End Cap for Guided Mounting: An end cap at the lower end of the assembly provides a clean termination and helps guide and protect the float when installed inside a stilling well, riser, or probe shaft.

Cathodic Boot Protection: A cathodic boot is included at the bottom of the assembly to help reduce galvanic corrosion on the stainless components when continuously submerged in diesel and water, improving long-term reliability.

System Compatibility: S4K2 is intended to be used with compatible Pneumercator magnetostrictive probes and tank monitoring systems that read both product level and water interface using dedicated float kits.

Typical Applications: Common uses include underground and aboveground diesel storage tanks, day tanks, and generator fuel systems where reliable detection of water beneath diesel is required to maintain fuel quality and protect downstream equipment.
