Lincoln Drive-Type Grease Fitting

Drive-type fittings are designed for fast production line installation in untapped holes to save thread tapping costs. Circumferential serrations on shank provide a hydraulic tight seal when fitting is installed properly. Cannot be used where high lubricant back pressures can be developed.

Hole sizes and shank dimensions are for reference use only. To determine optimum hole size, test applications should be conducted using the type of material into which the fitting is to be installed -- steel, cast iron, brass, aluminum, etc. Production tolerances of hole size must be taken into consideration when test is conducted.
