Overview

The Perko 012400099B is a replacement drain plug for the 0124000PLB garboard drain plug assembly. It is the plug only, not the full drain fitting, so it suits boats where the original Perko housing is still in place and only the removable plug needs to be renewed.

Fit is the main checkpoint here. This plug matches the 0124000PLB assembly, which uses a 1 in. NPT garboard drain and a 1/2 in. square plug drive. On a boat, that matters at launch, haul-out, and seasonal storage, when you need the drain to thread in cleanly and come back out without fighting a mismatched spare.

Key features

• Direct replacement plug for the Perko 0124000PLB garboard drain assembly
• Plug-only spare for keeping an existing drain body in service
• 1/2 in. square drive for wrench engagement during removal and reinstallation
• Matches the 0124000PLB assembly used with a 1 in. NPT garboard drain
• Useful to keep onboard or in the shop as a fit-specific spare before launch and winter layup

Compatibility and fit

This is a straightforward part when the boat already has the matching Perko drain fitting. It is not a universal garboard plug, so the safe match is the 0124000PLB assembly rather than a look-alike drain from another figure or another brand. If the flange and threads on the boat are damaged, replacing only the plug may not solve seepage.

Installation and setup

The 1/2 in. square head lets you work the plug with the correct wrench size instead of improvised pliers, which helps protect the plug and makes seasonal removal easier. Before reinstalling, clean the female threads in the drain body and check for wear or debris so the plug can seat fully.

Use on board

This part makes sense for owners who already know the boat is fitted with the Perko 0124000PLB drain at the transom or another low drain point. It is also a sensible spare to keep with haul-out gear if the boat depends on that drain for bilge or hull drainage during storage and service.
