Stillson Pattern Pipe Wrench Value Guide

The Stillson Pattern Pipe Wrench is a cornerstone of American industrial history, invented by Civil War steamboat engineer Daniel Chapman Stillson in 1869. This heavy-duty tool revolutionized plumbing by utilizing a tilting jaw mechanism that increases grip under pressure, preventing the crushing damage caused by earlier serrated tongs.

What Is Stillson Pattern Pipe Wrench Worth?

The typical price range for Stillson Pattern Pipe Wrench is $20 - $22 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

History of Stillson Pattern Pipe Wrench

Daniel Chapman Stillson, a steamboat engineer during the Civil War, invented this wrench design in 1869 while working for the Walworth Manufacturing Company. Before his invention, pipes were gripped with serrated tongs that often crushed the metal. Stillson's design used a tilting jaw to grip the pipe tighter as more pressure was applied, revolutionizing the plumbing and mechanical industries. His royalties earned him nearly $100,000 before his death, a massive fortune at the time.
