Rule Industries: The Standard-Bearer for Marine Plumbing Accessories

When it comes to keeping a vessel's water systems running cleanly and reliably, the supporting hardware matters just as much as the pump itself. Rule Industries has been synonymous with marine water management since 1965, and that same engineering DNA flows through every fitting, hose adapter, and strainer in their Plumbing Parts & Accessories lineup.

Since 1965, the Rule brand has been a trusted name in marine solutions, setting the industry standard with its high-performance submersible bilge pumps. That heritage of precision and durability extends naturally to the plumbing accessories designed to complement those pumps — because a world-class pump is only as good as the fittings and hardware that connect it to your boat's water system.

What Rule Plumbing Parts & Accessories Include

Rule's plumbing accessories are purpose-built to support the installation, maintenance, and long-term performance of marine pump systems. Key products in this category include:

• Hose Adapters — Heavy-duty molded, non-corrosive, high-impact plastic hose adapters designed to adapt existing hose to pump ports, eliminating the need to purchase new bilge hose. Available in straight and angled configurations to suit a variety of installation layouts.
• Replacement Strainers — Bilge pumps and water pumps should be fitted with a filter or strainer on the inlet plumbing to protect them from debris. Rule's Rule-Mate Pump Replacement Strainers are available in multiple sizes to fit round, square, and oval-base pump models, making maintenance straightforward.
• Pump Fittings & Accessories — Complementary hardware engineered to integrate seamlessly with Rule's pump family, ensuring leak-free, corrosion-resistant connections in demanding marine environments.

Built for the Marine Environment

What sets Rule's plumbing accessories apart is that they are designed hand-in-hand with the pumps they support. Features such as stainless steel shafts, marine-grade blocked wiring, and easy-to-clean construction contribute to overall system reliability. The same philosophy applies to their accessory hardware — high-impact plastic components will not rust, corrode, or discolor, making them ideal for the saltwater, moisture-rich conditions found aboard any vessel.

Water flow has been increased without increasing amperage draw by using an optimized impeller design across Rule's pump range, and the matching accessories are engineered to preserve that performance from pump port all the way to the thru-hull. Proper plumbing hardware ensures you never lose efficiency between your pump and your discharge point.
