Grease nipples are small straight or angled fittings used to dispense lubricants into machinery via a grease gun. By connecting a grease nipple to the gun, lubrication can be delivered precisely into hard-to-reach areas, ensuring smooth operation and reduced wear.
Each nipple contains a sprung ball bearing that compresses to allow lubricant to flow into the joint, then reseals to prevent contamination. They are available in both metric and imperial thread sizes to suit a wide range of equipment.
