ABSTRACT:
An apparatus and method for discharging vapocoolants in stream or mist form includes the use of selected fluoroelastomers for valve parts to regulate discharge. The fluoroelastomers provide long-term stability to the vapocoolants to enable superior shelf life without minimal loss or contamination of the vapocoolant. In addition, a filter is provided to remove contaminants from vapocoolant prior to passage through the nozzle opening.
