Raritan Plastic Piston Rod w/O-Ring f/PHII & PHEII

The Raritan Plastic Piston Rod w/O-Ring for PHII & PHEII is an essential replacement component for marine sanitation systems aboard pleasure boats worldwide. If you've spent years on the water, you know that Raritan marine toilets and waste treatment systems are workhorses in the head compartment—they handle the demands of extended cruising and daily use without fail. This piston rod assembly is the wear item that keeps your system functioning reliably, delivering consistent performance whether you're anchored offshore or living aboard in a busy marina.

Engineered specifically for Raritan PHII and PHEII toilet models, the plastic piston rod with integrated O-ring seal creates the watertight pressure cycle your system depends on. The O-ring maintains a critical seal during both intake and discharge strokes, preventing bypass and ensuring system efficiency. The compact 4 x 3 x 7-inch assembly weighs just half a pound, making installation straightforward—no heavy tools or complicated rigging required. This is genuine Raritan manufacture (MPN 1212W), meeting OEM specifications for chemical compatibility and durability in marine environments where corrosion and saltwater exposure are constant threats.

Cruisers and liveaboards benefit most from having this replacement on hand as preventive maintenance—a worn piston rod or degraded O-ring will reduce system performance and can lead to costly repairs if ignored. Installation fits directly into PHII and PHEII models, and the plastic construction provides long service life in the marine sanitation application. Whether you're preparing for an extended passage or simply maintaining your vessel's essential systems, this genuine Raritan component ensures your head stays operational and reliable for years to come.
