I think it is quite likely, the specified parts are made with a PEEK insulator.I remember having a teflon part machined for the company I was working for and the subcontractor used an inappropriate cutting fluid so the teflon was badly conductive. a week in the ultrasonic bath with HPLC grade 99.999% IPA didnt cure them, they had to be scrapped.
