Perko 5" Round Bronze Strainer MADE IN THE USA

The Perko 5" Round Bronze Strainer is a precision-engineered through-hull intake component designed for marine and watercraft applications where debris exclusion and controlled water flow are mission-critical. Built to professional marine standards, this cast bronze strainer serves as a protective barrier for seawater intake systems on vessels ranging from patrol boats to large displacement craft. The 5-inch outer diameter format accommodates a 2-inch through-hull fitting, making it compatible with standard marine plumbing architectures used across commercial, military, and recreational watercraft platforms.

Manufactured from cast bronze, the Perko 5" Round Bronze Strainer delivers corrosion resistance essential in saltwater environments and extended deployments where steel components would rapidly degrade. The drilled-hole design creates a uniform filtration medium that prevents larger debris—kelp, marine growth, and sediment—from entering cooling systems and intake manifolds while maintaining adequate flow rate for engine cooling demands. With a 3-3/4-inch inner diameter and eight-screw fastening configuration, the strainer integrates seamlessly into existing 2-inch through-hull assemblies without requiring adapter fittings or system modifications. The 0.85-pound weight and compact 5 x 1 x 5-inch profile ensure minimal topside footprint, critical for space-constrained vessel designs.

Maintenance personnel, boat engineers, and vessel operators rely on this strainer for preventive system protection during long-range operations, cold-water transitions, and high-fouling environments. Installation requires basic hand tools and takes minutes—simply align the eight screw holes with the through-hull flange and torque evenly to prevent binding. Routine cleaning (quarterly in saltwater, semi-annually in fresh water) removes accumulated debris and restores flow efficiency. Made in the USA, this Perko component meets the durability and reliability expectations of professional maritime operations and represents a cost-effective investment in engine longevity and system uptime.
