Raritan Engineering Plumbing Parts & Accessories

Raritan Engineering: Trusted Marine Plumbing Parts & Accessories

When it comes to keeping a vessel's plumbing system reliable, leak-free, and compliant with environmental regulations, few names carry more authority than Raritan Engineering. Since its founding in 1958, Raritan has operated as a family-owned business, with its products made in-house in Millville, New Jersey — a heritage that speaks directly to the consistency and craftsmanship found in every component they produce. Their plumbing parts and accessories are the backbone of that legacy, giving boaters the hardware they need to maintain, repair, and upgrade their onboard sanitation and water systems.

What Sets Raritan's Plumbing Parts Apart

Raritan stocks repair kits for most of their finished products and sells large and small replacement parts for all current production — and for as many years after that as possible. That long-term parts commitment is rare in the marine industry and makes Raritan an especially practical choice for owners of older vessels who need dependable sourcing for maintenance components.

The plumbing accessories lineup draws from decades of hands-on innovation. Raritan was the first company to develop a flow-through sewage waste treatment system suitable for small boats, well before any legal requirements existed — a product that evolved into the ElectroScan, which became the gold standard for small onboard treatment systems. The parts and accessories that support these systems — including strainers, vented loops, Y-valves, sanitation hose, and overhaul kits — reflect the same engineering rigor.

Working on a macerator pump is one of the most unpleasant jobs on a boat, but with Raritan Engineering's patented macerator pump with Waste Valve Assembly, the process is fast, clean, and easy — and because the system is so reliable, it puts an end to maintenance woes. The patented Waste Valve Assembly is a particularly notable innovation, isolating waste from the pump during service to keep maintenance cleaner and simpler.

Key Plumbing Accessories in the Raritan Lineup

Raritan's accessories catalog spans strainers, composite fittings, sanitation hoses, Y-valves, odor control products, and cleaning organics — all engineered to integrate seamlessly with their toilet and sanitation systems. Notable items include:

• In-Line Strainers — protect pumps from debris in raw water intake lines
• Vented Loops — available in multiple sizes to prevent back-siphoning
• Y-Valves — for directing waste flow between overboard discharge and holding tanks
• Sanitation Hose — odor-barrier hose sold to length for custom installations
• Overhaul & Repair Kits — model-specific kits for toilets such as the PH II and PHEII series, keeping proven systems running for decades
• Super Lube & Cleaning Products — bio-enzymatic treatment and lubricants formulated for marine sanitation use

Built for the Long Haul

Raritan toilet systems and their supporting plumbing accessories are self-contained and engineered to consume less water and low power, while remaining compact and easy to fit to sloped hulls, clean, and maintain. All-stainless-steel bolts are used to avoid corrosion problems, spring-loaded Viton shaft seals prevent premature leaks, and Raritan's proprietary rubber impeller compound allows for longer dry-running time. These design details show up throughout their parts catalog — components built to the same marine-grade standards as their complete systems.

Whether you're performing routine upkeep, replacing a worn seal, or upgrading a section of sanitation hose, Raritan Engineering's plumbing parts and accessories provide the dependable fit and materials that serious boaters expect.
