Drive Type, Grease Fittings
Drive fittings avoid tapping costs in variety of applications. Circumferential serrated shank provides a grease tight
seal when installed. They also simplify the replacement of damaged fittings in old or oversized holes. Recommended
only for low to medium pressure applications. Drive fittings must be used where high lubricant back pressures can
be developed.
Holes sizes and shank dimensions must be used as reference only. To determine optimum hole size, test applications
should be conducted using the type of material into which the fitting is to be installed ex. Aluminum, brass,
bronze, cast iron, copper, steel etc. Production tolerances of hole size must be taken into consideration when test
is conducted. Use lx-1430 drive fitting tool to install these fittings.
