Dorman Steel Expansion Plug

The Dorman Steel Expansion Plug line gives you a dependable way to seal openings in engine blocks, cylinder heads and other cast housings. These plugs are also called freeze plugs, welch plugs, core plugs or camshaft plugs. They are commonly used to seal the camshaft bore and casting holes left from manufacturing.

Key Features:

• Steel construction for durability and resistance to deformation under pressure
• Cup-style expansion design that seats firmly in the bore for a tight, leak-resistant seal
• Suitable for repairing or replacing leaking or corroded plugs
• Backed by Dorman's reputation for dependable replacement parts

Dorman is a well-known supplier of replacement parts for automotive repair. Each plug in this line is designed to give a secure, long-lasting seal, which helps protect against fluid leaks and engine damage. Installation is typically done by driving the plug flush into a clean, properly prepared bore. A sealant is often used as well.
