Oil Based Plunger Lubricant. Special blend of high quality lubricating oils with excellent lubricity, heat resistance. There are two common methods of application, (1) drip or (2) spray. In drip application, the lubricant should be dripped into the opening, and then completely dispersed by a blast of compressed air. In spray application, the lubricant is sprayed in aerosol form. The best spray dispersion is achieved via use of the “YG-Atomizing Block” but the lubricant can also be dispersed by other spray guns. Other methods of application may also be suitable in your working conditions.
