Product Details

The Sierra 18-56481 Brass Freeze Plug Kit is specifically engineered for marine engine applications, providing superior corrosion resistance in harsh saltwater and freshwater environments. This comprehensive kit includes all the brass freeze plugs needed for a complete engine installation, eliminating the risk of rust-out failures common with standard steel plugs.

Key Features:

  • Marine-grade brass construction resists corrosion and oxidation
  • Complete kit includes all freeze plugs required for full engine coverage
  • Designed specifically for marine applications and harsh environments
  • Direct replacement for OEM freeze plugs on compatible engines
  • Provides long-lasting protection against coolant leaks and freeze damage

Freeze plugs (also known as expansion plugs or core plugs) are critical engine components that seal the casting holes left from the manufacturing process. Brass construction ensures these plugs won't rust out over time, making this kit an excellent choice for boat owners and marine mechanics looking for reliable, long-term engine protection.
