Overview

The Perko 049300599D is a replacement stainless steel strainer basket for Perko 493 Series intake water strainers in the #5 size used with 3/4" NPT installations. It is made for raw-water strainer service where debris needs to be caught before it reaches pumps, heat exchangers, air-conditioning systems, generators, or other seawater-fed equipment.

The basket measures 1-13/16" in diameter by 6-1/4" high, which makes size confirmation important before ordering. This is the internal basket only, not a complete strainer assembly, so it is best matched against the existing strainer size and basket dimensions during maintenance.

Key features

• Replacement basket for Perko 493 Series #5 intake water strainers used with 3/4" NPT strainer installations.
• Stainless steel basket construction supports repeated cleaning in raw-water service.
• 1-13/16" diameter and 6-1/4" height help confirm fit before replacing a worn, damaged, or missing basket.
• Helps capture weeds, shells, scale, and other intake debris before it can move farther into the onboard water system.
• Suited for routine service on boats that rely on seawater intake strainers for engines, generators, air conditioning, or washdown-related plumbing.

Compatibility and fit

This basket is intended for the #5 size Perko 493 Series intake water strainer associated with 3/4" NPT plumbing. Before installation, compare the diameter, height, and strainer series with the basket being replaced, especially on older boats where strainers may have been serviced or changed over time.

Installation and maintenance

To service the strainer, close the seacock first, open the strainer housing, remove the old basket, and clean the inside of the bowl before placing the replacement basket in position. The basket should sit correctly inside the housing without being forced, and the cover gasket should be checked before the strainer is closed again.

Regular inspection is worthwhile on boats that run in weedy, silty, or shell-heavy water. Keeping the basket clear helps maintain steady raw-water flow and gives the operator a simple first check when cooling water, air-conditioning flow, or intake performance changes.

Use cases on board

This replacement basket is a practical service part for owners, yards, and technicians maintaining Perko raw-water strainers on cruising boats, fishing boats, sailboats, and small commercial vessels. It is especially useful to keep aboard when operating in areas where intake strainers load up quickly with grass, leaves, or floating debris.
