MJ-HAMMER is the specialized tool for assembling mechanical joints in underground water construction. Designed to reach where other tools can’t, it delivers the accuracy needed for leak-free connections.
MJ-HAMMER was born from the needs of the field, created to solve one of the most costly and frustrating challenges in underground water construction: achieving reliable, leak-free mechanical joint assemblies. What began as a simple idea has grown into a trusted standard, used by contractors and municipalities across the industry.
Every MJ-HAMMER is built on the principles of precision, durability, and efficiency, values that remain at the heart of our work today. Designed to make installations faster, safer, and more reliable, the tool represents a legacy of craftsmanship that continues to support the professionals who keep critical water systems running.
MJ-HAMMER was created to solve a simple but costly problem: getting mechanical joints right the first time. From the beginning, the focus has been on building a tool that crews can trust, one that combines practical design with lasting durability. That same commitment continues today.
Every MJ-HAMMER is made with the goal of making installations faster, reducing errors, and giving waterworks professionals the confidence that every joint will hold. It’s a legacy built on real-world experience, and it’s one we’re proud to carry forward.
