In-Line Strainer

In-Line Strainer – Compact Protection for Pumps and Plumbing

The Raritan In-Line Strainer is an essential upgrade for any marine vessel relying on raw water systems. Engineered to prevent seaweed, sand, and debris from entering your toilet or pump systems, this compact unit offers reliable protection that extends the life of expensive marine equipment while reducing maintenance time and odor issues.

Installed directly into your raw water intake line, the In-Line Strainer effectively filters out unwanted particles before they reach critical components like toilets, macerators, pumps, and cooling systems. One of the leading causes of marine pump failure is debris buildup—often from seaweed or fine sediment. By catching these particles early, this strainer helps you avoid performance loss, premature wear, and costly repairs.

The clear, high-strength plastic bowl makes visual inspection easy at a glance, so you can spot when cleaning is needed. A removable 20-mesh plastic filter allows for quick rinsing and reinstallation, without tools or hassle. Its ½" female NPT ports provide universal compatibility for most marine plumbing configurations.

Designed for both new installs and retrofits, the strainer can be mounted away from pumps for easier access in tight compartments. Whether you’re working on a compact sailboat or a large cruiser, its small footprint ensures it fits neatly into existing layouts.

Backed by Raritan’s one-year limited warranty and tested by hand for quality assurance, the In-Line Strainer is a simple yet powerful investment in system longevity. Reduce odors caused by trapped seawater, protect vital hardware, and enjoy fewer service interruptions—so you can spend more time on the water and less time in the bilge.
