A grease nipple is a metal fitting used in mechanical systems to feed lubricants, usually lubricating grease, under moderate to high pressure, into a bearing using a grease gun.

Grease Nipples

The fitting is permanently installed by a threaded connection, leaving a nipple connection that the grease gun attaches to.

Our range of hydraulic Grease nipples are manufactured to international standards and supplied across a wide range of thread types, styles and materials. Depending on the application and the installation sites, we can supply grease nipples according to international standards. Other than a standard version made of steel, zinc-plated and passivated, we offer many other types, made of brass or stainless steel. You will always find a solution in our range of products – even for the most challenging application.
