Collection:Grease Nipples

Grease nipples serve as fittings for lubrication. They consist of a threaded part that goes into a machine component and a nipple part that accepts grease from the grease press. They operate like a check valve, they let the grease in from the grease press, but not in the opposite direction. There are three types of grease nipples: hydraulic or ball DIN 71412, flat or button DIN 3404 and funnel DIN 3405.

If you notice your grease nipple is letting the grease out, replace it immediately. This usually means that some residue got into it and doesn’t allow closing. Pushing more grease in could only lead to that residue getting in your system.
