The legacy info below is for reference only.
Johanson has instituted a new Global Part Numbering (GPN) system.
Only the part number is changing. The parts are produced with the exact same materials, manufacturing processes, manufacturing controls, dimensions, physical attributes and testing as the parts supplied with the legacy part numbers.
The GPNs will be phased in over the next several years and are planned to be completed by January 1, 2026.
We will continue to quote and accept orders with the current (legacy) part numbers throughout this period.
Beginning January 1, 2022, all samples will be provided with the GPN.
Updates associated with this change will occur periodically.
