Rule Industries Nylon Pipe & Hose Fittings
Rule Industries Nylon Pipe & Hose Fittings: Marine-Grade Plumbing Built for the Bilge
When it comes to keeping a vessel dry and its plumbing reliable, few names carry more weight than Rule Industries. Since 1965, Rule has been a trusted name in marine solutions, setting the industry standard with its high-performance submersible bilge pumps. That same engineering philosophy — build it tough, build it right — carries directly into their line of nylon pipe and hose fittings, which are designed to integrate seamlessly with Rule pump systems aboard recreational and commercial vessels alike.
Why Nylon for Marine Plumbing?
Material choice matters enormously in a saltwater environment. Rule's nylon fittings are molded from heavy-duty, high-impact plastic and are rust and corrosion proof — critical qualities for any component exposed to bilge water, raw water, or the relentless humidity of life below deck. Unlike brass or bronze fittings that can suffer from galvanic corrosion or dezincification over time, nylon holds up without the need for special coatings or anodes, making it a smart long-term choice for freshwater and saltwater plumbing alike.
Designed to Work With Rule Pump Systems
Rule's nylon hose fittings aren't generic hardware — they are purpose-built accessories for a complete marine plumbing ecosystem. These fittings are designed to adapt existing hose to pump ports, eliminating the need to purchase a new bilge hose. Configurations include both straight and stepped adapters as well as elbow versions for tight installations. Straight or double-stepped adapters are used for Rule pumps and thru-hulls, while 90° elbow adapters are suited for rigid pipe installations of sump and utility pumps. Notably, the adapters snap onto the discharge port without the need for a hose clamp, simplifying installation even in confined bilge spaces.
A Brand That Understands Marine Demands
The history of Rule Marine started more than half a century ago in Beverly Farms, Massachusetts, founded by engineer and inventor Clinton Rule, whose struggle with a leaky boat inspired him to create a new solution. That origin story still resonates in every product the brand produces. Rule submersible bilge pumps have set the standard for the industry for decades and are the first choice of yachtsmen and commercial fishermen throughout the world. When a brand's pumps are trusted at that level, the fittings and accessories that connect them must meet equally high standards — and Rule's nylon plumbing fittings are built with exactly that expectation in mind.
Straightforward Installation, Lasting Reliability
Rule's assortment of accessories and fittings are designed using innovative and effective technology, and are known for their high quality, long-lasting durability. For boaters performing a bilge pump installation or upgrade, having a fitting that pairs natively with Rule pump hardware eliminates guesswork around sizing and compatibility. Whether you're routing discharge hose through a locker, adapting to an existing through-hull, or configuring a new pump installation from scratch, Rule's nylon fittings keep the job clean and the system sound.
