Jabsco Pumpguard In-Line Strainer - 1/2" NPT Port

The Jabsco Pumpguard In-Line Strainer with 1/2" NPT Port is a stainless steel intake protection system designed to prevent debris, rust, and scale from entering your pressure water pump or bilge pump. This inline strainer sits upstream of the pump in any orientation, acting as a sacrificial filter that extends pump life by catching contaminants before they reach internal valve and impeller components—a critical safeguard in marine environments where tank sediment and corrosion byproducts constantly threaten pump integrity.

The clear inspection housing lets you monitor strainer loading at a glance, and the stainless mesh screen can be cleaned in minutes without disassembly or special tools. The 1/2" NPT port threads directly into standard marine plumbing fittings, making installation straightforward on new builds or retrofit applications. Because it works in any position—horizontal, vertical, or angled—the Pumpguard adapts to real-world deck layouts and cramped engine compartments where conventional strainers won't fit. The transparent design eliminates guesswork: when flow slows or pressure drops, you see immediately whether cleaning is needed rather than discovering a failed pump under way.

This strainer is essential for offshore anglers running high-demand freshwater systems, cruising sailboat owners relying on engine cooling loops, and commercial fishermen operating in silty or mineral-heavy waters. Weekend boaters benefit equally—a five-minute maintenance task prevents costly pump replacement and keeps cabin showers and engine cooling reliable throughout the season. Install one on pressure water intake and bilge pump intake lines to protect both systems with a single proven product.

Jabsco strainers are industry standard in marine original equipment, trusted in both freshwater and saltwater applications. The NPT thread standard ensures compatibility with aftermarket sea cocks, through-hull fittings, and manifold blocks stocked by marine suppliers worldwide.
