KTM1190 Adv Tyre Pressure Monitor Sensor (TPMS) needed

Ok ... I damaged my KTM 1190 Adv valve threat at garage when i tried to fit air fitting.  As the valve nossle is made from aluminium it stretched and tor as can be seen on photo. Unfortunately this valve forms part of the Tyre Pressure Monitor Sensor (TPMS) which is pricey.  Does anybody know were i can get one or purchase a used one at a more reasonable price.... Or is there some sort of a fix for this problem.  PLEASE
