Flex-A-Lite 106781 Zinc Anode Drain Plug Replacement Kit 1/4 NPT

The Flex-A-Lite 106781 Zinc Anode Drain Plug Replacement Kit provides proven protection against electrolysis and corrosion damage in automotive cooling systems. Originally used in heavy-duty and marine applications, this zinc anode technology now brings affordable insurance to passenger vehicles, trucks, and performance applications.

How It Works:

Modern vehicles contain numerous aluminum components in their cooling systems, including radiators, water pumps, and engine blocks. These aluminum parts are vulnerable to corrosion from electrolysis caused by electrical current flow through the coolant or coolant additive breakdown. The Flex-A-Lite zinc anode acts as a sacrificial element that will be attacked and eroded before any aluminum components in your cooling system, effectively protecting your expensive cooling system parts by corroding itself instead.

Key Features:

• 1/4-inch NPT male threads for universal fit
• Installs in place of radiator drain petcock in most applications
• Can be installed in any 1/4-inch NPT port in the cooling system
• Brass and zinc construction for maximum corrosion protection
• Sold individually as complete replacement kit
• Easy installation with no special tools required

Applications:

This zinc anode kit is designed for radiators equipped with a 1/4-inch NPT bushing welded into the tank, though it can be installed in any available 1/4-inch NPT port in the cooling system. It provides cost-effective protection for aluminum radiators, water pumps, heater cores, and other cooling system components against galvanic corrosion.
