Grease fitting thread dimensions available at bottom of page.

Grease fittings are used in mechanical systems to add grease with a grease gun. The fitting is permanently installed by a threaded connection which leaves a nipple connection for the grease gun to attach to. By using the pressure in the grease gun, grease is added to the system through the fitting. Grease Fittings are useful for machine lubrication which is critical for safe and reliable operation of your equipment.
