Direct answer: The current U.S. ZUPPER ME-1225 kit is a cordless PEX-A expansion tool for ASTM F1960 connections. Its listed expansion heads are 1/2 in., 3/4 in. and 1 in. Match the connection system, fitting/ring specification and nominal pipe size to the exact current listing before ordering.

What the real ME-1225 footage shows

In ZUPPER's exact-model operation footage, the operator places the expansion head in a PEX pipe end, actuates the tool, removes the head and brings the pipe end to a fitting. This is a visual example of the expansion workflow, not proof that every fitting, ring brand or head size is interchangeable. View the ME-1225 product page and real operation video.

Current U.S. expansion-head sizes

Listed head Ordering check
1/2 in. Confirm a matching PEX-A pipe, fitting and ASTM F1960 ring configuration.
3/4 in. Confirm a matching PEX-A pipe, fitting and ASTM F1960 ring configuration.
1 in. Confirm a matching PEX-A pipe, fitting and ASTM F1960 ring configuration.

The listed head sizes describe the current U.S. kit configuration. A matching nominal size alone does not establish compatibility with a different connection method.

Five checks before ordering

  1. Confirm the project uses PEX-A expansion, not a PEX-B copper crimp ring, clamp or sleeve-press connection.
  2. Confirm the fitting and ring system specified for the job is ASTM F1960.
  3. Match the nominal pipe and fitting size to one of the three heads listed above.
  4. Review the exact current U.S. PDP for the included heads and package components.
  5. If the required size, head or fitting system is not listed, ask ZUPPER for exact-model confirmation before ordering; follow the pipe and fitting manufacturer's installation instructions.

What the current listing does not establish

3/8 in. is not established by the current U.S. ME-1225 listing. The listing also does not establish PEX-B, ASTM F1807, ASTM F2098, PureFlow or third-party head compatibility. This is a boundary on what the current listing verifies, not a claim about every regional or future configuration.
