Product Details

The Dorman 550-025 is a concave steel cup expansion plug designed for reliable engine block and cylinder head sealing applications. This freeze plug features a 1-3/4 inch diameter and 0.145 inch height, providing a precise fit for specific engine applications.

Key Features:

  • Concave steel cup design for secure installation and sealing
  • 1-3/4 inch diameter for exact fitment
  • 0.145 inch height profile
  • Durable steel construction resists corrosion and withstands engine temperatures
  • Direct replacement for worn or damaged expansion plugs

Expansion plugs, commonly known as freeze plugs or core plugs, seal the core holes left in engine blocks during the casting process. This Dorman plug restores proper sealing to prevent coolant leaks and maintain engine integrity. The concave design allows for proper installation depth and creates a reliable seal when driven into place.

Amazing prices, cheapest I could find anywhere. Only down side is the shipping is more than it should be.

Very happy with my purchase and product from Autoplicity! Highly recommend.

Fine

thanks

I was looking for KC lights for my jeep, not only CI they have just the ones I was looking for, they were half the price of any local auto shop! Shipping costs were very low to. Thanks!

Great product and half the price of any one else I've shopped would recommend this to everyone.

autoplicity has the lowest price and fast service .I will definitely use autoplicity for my next auto parts purchase

At first I did not expect Autoplicity to even carry this part, but in fact they did. Placed the order and I received the part quickly. They were the cheapest for the part after searching nearly everywhere. Will order from them again.<br>Order #8334

I ordered the Truxport tonneau cover for my Nissan Frontier. I am very happy with Autoplicity,they have the best price by far on this product,and they promptly sent me an email when it was shipped.....the ONLY thing I wish they would have done but didn't is to include a tracking number. I think the reason they didn't include it is that it was shipped directly from the manufacturer,but they did give me the tracking number when I called and asked for it. Overall a very positive experience
