Trimo Pipe Wrench Value Guide

The 1940s Trimo Pipe Wrench is a staple of American industrial history, manufactured by the Trimont Manufacturing Company using heavy-duty drop forged steel and cast iron. These wrenches are highly collectible due to their association with Daniel C. Stillson's revolutionary design and their enduring reputation for indestructible construction.

What Is Trimo Pipe Wrench Worth?

The typical price range for Trimo Pipe Wrench is $15 - $25 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Condition of the hardened teeth; sharp, well-defined teeth command higher prices than those worn smooth from heavy use.
• Presence of original finish or patina, as excessive rust or modern over-painting can decrease the $15-$25 market value.
• Operational smoothness of the adjustable knurled nut and the spring tension within the jaw mechanism.
• Size of the wrench, with larger industrial versions or very small 'pocket' sizes often fetching different premiums within the collector market.

How to Identify Trimo Pipe Wrench?

• Look for the 'TRIMO' trademark embossed in block lettering on the handle or the movable jaw.
• Verify the material construction, which should consist of a drop forged steel head and a rugged cast iron frame.
• Check for the 'Made in USA' or 'Trimont Mfg. Co. Roxbury, MA' stamps often found on authentic 1940s era models.
• Inspect the jaw teeth for the specific hardened pattern designed to grip metal pipes without slipping.

History of Trimo Pipe Wrench
