DNJ Engine Components Brass Freeze Plug Expansion Plug

DNJ Engine Components Brass Freeze Plugs, also called expansion plugs, core plugs, welch plugs or engine block plugs, seal the casting holes left in an engine block and cylinder head after manufacturing. They are a dependable replacement when an old plug has rusted, leaked or been pushed out.

Key Features:

• Brass construction: Resists corrosion and rust from coolant and moisture, so it lasts longer than many plain steel plugs.
• Cup-style press-fit design: The plug expands against the bore wall when it is installed, which forms a tight, leak-resistant seal.
• Reliable coolant sealing: Keeps coolant in the water jackets of the block and head.
• Engine rebuild ready: Suited to engine rebuilds, overhauls and routine cooling system repairs.

DNJ Engine Components supplies quality engine rebuilding parts for domestic and import applications. Choose the variant that matches your bore requirement. Replacing freeze plugs during a rebuild or whenever the block is exposed helps prevent leaks and costly repairs later.
