I have (19) NEW Retaining Caps that are for a 45/65/85/105 Amp Hypertherm Plasma Gun. They are part #220953ATTC. They are made by American Torch Tip(ATTC). They are the same as Hypertherm Part # 220953. They are NEW, and in the bag. Im am asking $15 for each of them. They they are designed to work with a table torch application, as they have a clamped on clip for wire grounding on a table torch application, but they will also work on a regular hand held gun also.
