Is the PTFE coupler for the upgrade kit different from the coupler in the UM2? We have 3 UM2 printers that we've had to change out the coupler, as they burn out after time. Just wondering if the PTFE coupler that is listed on the spare parts page is the for the newer + printers. I would like to order a few at the same time as ordering the upgrade kits but want to make sure it is the right one. thanks
