Perko 0493 Intake Water Strainer Spare Parts, For #9 2 in Strainer

Overview

The Perko 493 Series is a set of intake water strainer spare parts for servicing Perko raw-water strainers used on engine cooling and other seawater intake lines. This range covers replacement pieces such as castings, the transparent cylinder, cover and gasket parts, hinged cover hardware, gasket kits, and tie rod hardware.

The 0493 strainer layout uses four outside tie rods, side mounting lugs, and a removable cover arrangement for basket access. These spare parts help keep that serviceable layout in working order when an individual component is worn, damaged, corroded, cracked, or due for replacement during routine maintenance.

For engine-room and bilge installations, correct fit matters more than appearance. The existing strainer model, size, gasket arrangement, and old hardware should be identified before replacement so the new part lines up with the body, cover, cylinder, and fastening points already on board.

Key features

• Replacement parts for Perko 0493 and 493 Series intake water strainers used in raw-water intake systems.
• Range includes top casting, bottom casting, transparent cylinder, cover with gasket, hinged cover hardware, gasket kits, and tie rod hardware.
• Transparent cylinder option keeps the basket area visible for routine checks without opening the strainer.
• Cover, gasket, hinged bolt, and tie rod parts support common service points related to sealing, clamping, and basket access.
• Gasket options include cork and rubber kits, allowing the replacement material to match the existing strainer setup.
• Service-parts approach helps repair the installed strainer instead of replacing the full assembly when only one component needs attention.

Variants

The available configurations vary by replacement component, not by color, finish, or electrical specification. The range includes body castings, cylinder parts, cover sealing parts, gasket kits, hinged cover hardware, and tie rod hardware for the Perko 493 Series strainer family.

Part selection depends on the installed strainer size and the component being replaced. Some hardware and cylinder parts in this group are associated with larger 493 Series strainers, while gasket and cover-related parts need to match the existing cover and body arrangement already fitted on the vessel.

Compatibility and fit

This product family is most relevant for boats already fitted with a Perko 493 Series intake water strainer. It is not a universal raw-water strainer kit, and the individual spare part must correspond to the original strainer body, pipe-size version, and component location.

Before ordering, the safest reference points are the old part, the strainer casting markings, the installed strainer size, and the current gasket or cover layout. A correct match helps avoid leaks at the cover, uneven compression at the cylinder, or hardware that does not seat correctly.

Installation and service

These parts are typically used during strainer rebuilds, leak repair, seasonal service, or replacement after corrosion, cracking, thread wear, or gasket compression. The strainer should be isolated from the seawater intake before service, and sealing surfaces should be clean before a new gasket, cover, cylinder, or hardware set is installed.

After reassembly, the cover and tie rods should compress the strainer evenly. Once the seacock is reopened and the engine or pump is running, the strainer should be checked for seepage around the cover, cylinder, drain area, and fasteners.

Use cases on board

These spare parts are a practical match for maintenance teams, boatyards, and owners keeping a raw-water strainer in service on inboard engines, generators, air conditioning systems, or other seawater-fed equipment. They are especially useful when the strainer body is still serviceable but a specific cover, cylinder, gasket, casting, or fastening component needs replacement.
