Perko 304 Stainless Steel Basket Strainer Only Size 4 f/1/2" Strainer

The Perko 304 Stainless Steel Basket Strainer Only Size 4 for 1/2" Strainer is a precision-engineered replacement strainer basket designed for marine and industrial fluid intake systems. Constructed from marine-grade 304 stainless steel, this strainer basket resists corrosion in saltwater and chemically aggressive environments, making it ideal for offshore applications, coastal installations, and freshwater systems where durability and contamination prevention are critical. As a replacement component rather than a complete assembly, this basket is engineered to work as a direct drop-in substitute for existing Perko Size 4 strainer housings.

The basket measures 1-13/16 inches in diameter by 4-1/16 inches in height, with an overall height of 5-5/8 inches when the hoop handle is attached. These dimensions are precisely calibrated to fit Perko 1/2"-NPT strainer housings, ensuring proper mesh filtration capacity and fluid flow rates. The 304 stainless steel composition offers superior resistance to rust and pitting compared to lower-grade steel alternatives, extending service life even in high-humidity, salt-air, or corrosive-fluid environments common in marine and industrial settings.

This strainer basket suits operators and technicians responsible for maintaining cooling systems, seawater intake lines, fuel systems, and process water circuits aboard vessels, offshore platforms, and industrial facilities. Preventive maintenance of strainer baskets—regular cleaning and timely replacement—protects downstream equipment from particulate damage and maintains system efficiency. The Perko 049300499D (MPN 049300499D) is an OEM-specification component backed by Perko's established reputation in marine hardware engineering.

When sourcing replacement strainer baskets, verify that the Size 4 designation and 1/2"-NPT connection match your existing strainer housing to ensure proper fit and filtration performance.
