The Buddy Wrench™ — The Original 3-Jaw Adjustable Flare Nut Wrench

Grip stronger. Slip less. Work faster.

The Buddy Wrench™ is the patented 3-jaw adjustable flare nut wrench engineered for professionals who deal with stubborn, rounded, or hard-to-reach flare nuts. Whether you’re in Aviation, HVAC, Automotive Repair, Refrigeration, Diesel Mechanics, or Industrial Maintenance, this tool delivers the grip, leverage, and reliability you need on the job.

Designed by an Air Force Veteran and crafted through years of real-world testing, The Buddy Wrench solves one of the most common Technician frustrations: flare nuts that won’t budge or that begin to round under traditional wrenches. Its unique 3-jaw system grips more surface area than standard two-jaw or open-end wrenches, giving you unmatched control with zero slip and no damage to the fitting.
