Mytee Dry GT Upgrade Kit. Changes model 8400M Mytee Dry tool into 8400GT Mytee Dry GT Upholstery Tool.
For 8400DX models (All-plastic housing), P600C is also needed to complete this upgrade.
For 8400DX models BUILT BEFORE 2019, H572 is also needed to complete this upgrade, in addition to P600C. (If you are unsure, look for the bracket pictured below supporting the valve inside the tool handle, if you do not have one, include H572 in your upgrade order.)
