MJ adapters are currently produced by several manufacturers and used by water utilities to transition from ductile iron or other piping materials using standard mechanical joint connections. A standard is needed to harmonize dimensions for critical features such as length, pilot nose design, and features for heat fusion joining. Users have reported inconsistent dimensions from one manufacturer to another that cause issues during installation.
