Perko 6" Round Bronze Strainer MADE IN THE USA

The Perko 6" Round Bronze Strainer (Model 0086006PLB) is a cast bronze through-hull intake strainer engineered for marine applications where raw water cooling systems require reliable filtration and corrosion resistance. This made-in-the-USA component prevents debris, sediment, and marine growth from entering engine cooling lines, water systems, and other through-hull applications on vessels operating in both freshwater and saltwater environments.

Built from cast bronze, the Perko strainer combines exceptional corrosion resistance with durability in harsh marine conditions. The 6-inch outer diameter (O.D.) and 4.25-inch inner diameter (I.D.) design accommodates a 2.5-inch through-hull fitting, with drilled holes providing effective filtration while minimizing flow restriction. The 10-screw fastening system ensures secure mounting and easy maintenance access. At 1.3 lbs, this strainer integrates into existing systems without adding significant weight or complexity.

This strainer serves operators, boat owners, and marine technicians who demand reliable intake protection for diesel and gasoline engines, air conditioning systems, and hydraulic cooling loops. The bronze construction outperforms painted steel alternatives in saltwater service, where galvanic corrosion and rust penetration reduce component lifespan significantly. Replacement and maintenance are straightforward—the external basket design allows quick access to internal passages without complete system disassembly, minimizing downtime during seasonal inspections or after extended cruising in dirty water conditions.

Perko has manufactured marine hardware to OEM and aftermarket standards for decades. This 6-inch strainer represents the engineering standard for mid-size through-hull systems and pairs with standard 2.5-inch skin fittings found on most production and custom vessels. Stock this component as preventive maintenance or keep one aboard as a spare—Bronze strainers with matched through-hull fittings are essential backup items on any offshore-capable vessel.
