Raritan Shaft Seal f/PH & PHII

The Raritan Shaft Seal for PH and PHII marine toilets is a precision replacement component engineered specifically for Raritan's PH and PHII waste treatment systems. This seal is the critical component that prevents raw sewage or treated waste from leaking around the rotating shaft, maintaining a watertight bond between the pump mechanism and the hull-mounted installation. For cruising sailors, fishing vessel operators, and anyone depending on reliable onboard sanitation systems, a failed shaft seal means potential waste backup, odor, and contamination—making this a maintenance item every boat owner should keep on hand.

Raritan's shaft seal is manufactured to OEM specifications and direct-fit compatibility with PH and PHII models, eliminating guesswork during replacement. Marine-grade materials are selected to resist corrosion from saltwater exposure and the chemical environment of waste systems. The seal's compact design (1 x 1 x 1 inch) and minimal weight (0.1 lbs) make it practical to carry aboard as spare inventory. Installation requires no special tools or expertise—standard shaft seal replacement procedures apply. Keeping a spare Raritan Shaft Seal (MPN 1214A) aboard eliminates the risk of system failure in remote anchorages or during extended passages where replacement parts may not be available.

This seal is essential for any vessel operator running Raritan PH or PHII systems—from weekend cruisers to commercial fishing boats. Routine maintenance intervals depend on water quality, usage frequency, and preventive flushing practices, but seals typically require replacement every 3–5 years of active use. Having an OEM-specification replacement on hand before problems develop protects your marine investment and ensures uninterrupted waste system operation during critical times. Raritan's commitment to environmental responsibility and marine equipment reliability makes their OEM parts the safest choice for long-term system performance.
