Overview

The Perko 0493DP799L is a bronze hinged cover bolt with pin, nut, and washer for Perko 493 Series raw water intake strainers. It fits 493-DP6 and 493-DP7 strainers, which correspond to the larger 1 inch and 1-1/4 inch pipe size units in this strainer family.

This replacement hardware is used at the strainer cover, where secure clamping matters for routine basket checks, cleaning, and winterizing. It is a practical service part for engine raw water intakes, generator intakes, and other onboard seawater systems using the compatible Perko 0493 strainer sizes.

Key features

• Replacement hinged cover bolt assembly for Perko 493 Series raw water intake strainers.
• Fits Perko 493-DP6 and 493-DP7 strainer configurations.
• Used with 1 inch and 1-1/4 inch pipe size strainer units.
• Bronze bolt hardware matches the cover hardware requirements of the compatible strainer sizes.
• Helps restore proper cover clamping when the original bolt, pin, nut, or washer is worn, lost, or corroded.
• Useful for maintenance on raw water strainers serving engines, generators, and seawater plumbing systems.

Compatibility and fit

This part is specific to Perko 0493 Series intake water strainers in sizes 6 and 7. Before ordering, match the strainer model or existing hardware against 493-DP6 or 493-DP7 rather than relying only on the general strainer family name, since smaller and larger 0493 strainers use different replacement cover hardware.

Installation and service

The hinged cover bolt is part of the hardware that secures the strainer cover during normal operation. During installation, the cover gasket and sealing surfaces should be checked at the same time, since raw water strainers are opened regularly for basket cleaning and sediment removal.

For boats kept in saltwater or used often, this is the kind of service part worth checking during engine room inspections. Replacing worn cover hardware can make future basket access easier and helps keep the strainer cover seated as intended.
