The safer, more efficient way to tighten or loosen Hammer Union connections.

While current methods require the exhausting motion of continually banging a hammer to turn the lug, the HU Tool is designed specifically for these connections, removing the hammer from your hands and the fatigue from your arms. The HU Tool and interchangeable heads will fit on all registered Hammer Union sizes.

Seriously, put the hammer down.


The safety increases exponentially when you remove a hammer from a situation and add a tool that does not require a dangerous swinging motion to operate. 

Hands-free Operation

Once the tool is applied to the Hammer Union connection, no hands are required to hold the tool in place. Additionally, the tool has an optional handle that can be attached, if preferred, in order to hold the tool safely. 

Spring Head

The head features the same patented open-gate design as Torq/Lite’s JN Series wrenches, but has a spring-latch feature that makes applying and removing the tool very simple. 


With only the need for one HU Tool, our interchangeable heads are the only thing you'll need to be changing when tightening or loosening Hammer Union connections. Each head includes a welded in jaw that clamps to the application and turns as it advances for a more efficient way to work. The HU Tool and our entire range of interchangeable heads will fit on all registered Hammer Union connections.


Throughout their lifespan, the Hammer Union lugs can take a lot of beatings - literally. The HU Tool reduces the impact on those lugs, saving replacement time and costs. 

Reduces Fatigue

Swinging at a hammer is not only dangerous, it can wear you out. The HU Tool saves the shoulders of the operators, keeping them safe, and making them more productive. 



*The HU Series will work with any standard torque wrench pump.
