The tool that gauges PEX joints joined by a band is called?

Explanation:
A go/no-go gauge is used to verify PEX joints joined by a band. After crimping, you slide the gauge over the joint to check tolerance. The go end should fit, showing the crimp is tight enough to meet the minimum dimension. The no-go end should not fit, indicating the crimp isn’t over-crimped beyond the maximum dimension. If the go end won’t fit or the no-go end fits, the joint isn’t within spec and should be redone to prevent leaks. This tool directly tests the critical crimped diameter that governs seal and fit, which other instruments like a caliper, dial gauge, or tape measure don’t reliably assess for this purpose.
