Abstract
An improved method and apparatus for perforating and applying grease through a resilient seal using a solid or hollow needle, said solid needle puncturing the seal with a sufficiently small perforation that, as the device is maintained in contact with the seal and pressurized lubricant is applied, the perforation is hydraulically opened by the grease, and wherein, upon removal of the device, the perforation will self-seal due to the resilient character of the seal material.
