Advancements in Hydraulic Bolting: A New Era of Innovation

Torq/Lite's Hydraulic Torque Wrench IUXL

Pioneering Precision in Hydraulic Torque Wrenches

Since 1981, Torq/Lite has been at the forefront of hydraulic torque wrench innovation in the U.S.A. Their ISO-9001 certification is a testament to their unwavering dedication to quality, safety, and excellence.

In collaboration with ESI for a decade, Torq/Lite® has revolutionized the bolting industry with their patented inline torque wrench design, known as IUXL. This design ingeniously integrates the body with the cylinder unit, streamlining the interchangeable component to just the head. This innovation sets them apart from competitors who necessitate the removal of half the body for different nut sizes. The result? More compact cases, reduced material usage, and enhanced production efficiency. For the end-user, this translates into diminished operator fatigue, lower costs, and heightened efficiency. A true embodiment of Torq/Lite’s commitment to advancing the industry standard.
