Q: Where do I crimp ZoomLock MAX fittings?

A: Crimp with the jaw straddling directly over the O-ring section of the fitting, as in the image below.


Q: How many crimps can you complete on a complete battery charge?

A: That is tool dependent; consult the tool manufacturers owner’s manual.

  Q: How do you know when to service the tool?

A: That is tool dependent; consult the tool manufactures owner’s manual.

  Q: What is the expected life of the jaws?

A: ZoomLock MAX jaws are laser hardened and have a finite life expectancy. We encourage each customer to have the jaws and tools serviced and checked annually or every 10,000 crimps depending on which comes first.

  Q: What tool manufacturers and models are ZoomLock MAX jaws compatible?

A: Please refer to the Press Tool Compatibility table below.

  Q: What is the expected lifetime of the jaws and how do you know when you need to replace the jaws?

A: Check jaws at the latest one year after the purchase or after 10,000 pressings (according to whichever occurs first) by an authorized Rothenberger testing center. Repeat these checks at the latest one year or another 10,000 pressings after the previous inspection. During jaw inspection, check the jaws for operating and functional safety and wear parts (e.g., springs). Functionally and operationally safe jaws are returned.

  Q: Where can replacement batteries and chargers be purchased?

A: That is tool dependent; check the tool manufacturer owner’s manual.
