Raritan Engineering Sanitation Hose

Raritan Engineering Sanitation Hose: Purpose-Built for Marine Heads

When it comes to keeping a boat's onboard plumbing odor-free and reliable, the hose connecting the head to the holding tank is often the weakest link. Raritan Engineering, a name synonymous with marine sanitation since 1958, addresses this challenge head-on with their flagship SaniFlex Odor Shield Marine Hose — engineered specifically for the demanding world of marine sanitation hose applications.

What Sets SaniFlex Apart

Most boaters have wrestled with the familiar problem of sanitation odors permeating through the walls of standard PVC hose. Raritan's answer is a fundamentally different material approach. Unlike conventional hoses, SaniFlex uses a white butyl rubber compound that blocks odor 15x better than PVC. Backed by a 10-Year Odor-Free Warranty, SaniFlex reflects Raritan's commitment to engineering sanitation systems that last.

Odor resistance alone wouldn't be enough for the rigors of marine plumbing. At the core of SaniFlex's durability is a double steel wire helix embedded in premium butyl rubber — construction that allows the hose to withstand kinking, crushing, and collapse during tight bends or heavy-duty installations, ideal for heads located in confined spaces. With a burst pressure rating of 315 PSI, SaniFlex is ready for anything from macerating toilet systems to vacuum-based waste setups, even under high surge or negative pressure conditions.

Installer-Friendly Design

Any experienced marine mechanic will tell you that ease of installation matters just as much as performance specs. SaniFlex Odor Shield is designed so that no heat or lubricants are needed during installation, and its ability to bend on a 3½" radius makes it one of the most flexible sanitation hoses on the market. It can easily be installed on standard hose barb fittings without excessive effort, with no need to heat or lubricate the hose. For boatbuilders and do-it-yourself refit sailors alike, this translates to faster jobs, fewer callbacks, and a more professional finished installation.

A Brand with Deep Marine Sanitation Roots

Raritan Engineering Company was founded in 1958 on the basis of a patent for the PH Marine Toilet, whose successor, the PHII, is still manufactured today; the Crown Head — the world's first macerating marine toilet — followed in 1966. That legacy of sanitation engineering is what makes Raritan's approach to hose design credible: SaniFlex is made by Raritan, a name trusted for over 60 years in marine sanitation. Raritan is a U.S. manufacturer, with products assembled in Millville, NJ.

Whether you are replacing aging discharge plumbing, running new lines during a refit, or building out a complete holding tank system from scratch, Raritan Engineering's sanitation hose lineup is purpose-built for the job.
