Perko 0443 Lightweight Intake Water Strainer Spare Parts

Overview

The Perko 0443 Lightweight Intake Water Strainer is a spare-parts range for the Perko lightweight raw-water intake strainer used in marine seawater pickup systems. These parts support service and repair of the strainer assembly, including the top casting, transparent cylinder body, basket strainer, cover with gasket, hinged cover hardware, rubber gasket kit, and nuts with washers.

The 0443 strainer uses cast bronze components with a clear polymer body, so the basket area can be checked without taking the assembly apart. The strainer basket is made from 316 stainless steel, with 0.079 inch screen holes and 47 percent open area, helping the unit pass cooling water while trapping debris before it reaches pumps, heat exchangers, air-conditioning systems, generators, or other raw-water equipment.

This range is useful when the full strainer does not need to be replaced, but a worn gasket, cracked cylinder, damaged cover, missing hardware, or clogged basket needs attention. Matching the replacement part to the existing Perko 0443 strainer size and casting details is important before ordering.

Key features

Variants

This spare-parts range is offered in several service configurations. The options cover the main castings, the transparent cylinder body, the basket, the cover and gasket area, the hinged cover bolt assembly, the rubber gasket kit, and the nuts with washers used on the 0443 strainer series.

The part that changes between variants is the replacement component itself. The rest of the fit depends on the installed strainer size and the exact Perko figure number on board, so the existing strainer markings and the part being removed should be checked before purchase.

Compatibility and fit

These parts are intended for Perko lightweight intake water strainer service, especially installations based around the 0443 clear-body strainer. The 0443 range includes common pipe sizes from 1/2 inch through 1-1/2 inch, and individual service parts can be size specific. Gasket kits are especially important to match correctly because older and newer strainer assemblies may not use the same gasket material.

For a clean fit, compare the existing casting, body, basket, cover, and gasket layout before ordering. On boats with limited engine-room access, also check that the cover can be opened far enough to remove the basket after the replacement part is installed.

Installation and setup

Before servicing the strainer, close the seacock and relieve any water pressure in the raw-water line. The basket and cylinder area should be cleaned while the assembly is open, and gasket seating surfaces should be checked for scale, old gasket material, and scoring before the new part is fitted.

When reinstalling the cover or body, tighten hardware evenly so the gasket compresses without twisting. After the seacock is reopened, inspect the assembly under running conditions for drips, air leaks, and steady water flow to the equipment it protects.

Use cases on board

This spare-parts range is a practical match for owners and service yards maintaining raw-water strainers on inboard engines, generators, air-conditioning systems, washdown pumps, and other seawater-fed equipment. It is especially helpful when the strainer body is still serviceable and only the basket, gasket, cover hardware, or clear cylinder needs replacement.

Maintenance and care

Raw-water strainers should be checked often in weed-heavy harbors, shallow anchorages, and silty areas. A transparent cylinder makes routine inspection quicker, but the basket still needs to be removed and cleaned as part of normal service.

Gaskets should be replaced when they become flattened, cracked, swollen, or difficult to seal. During winterizing, draining the strainer and cleaning sediment from the lower area helps reduce freezing damage and makes spring commissioning easier.
