This 45-degree angle grease nipple provides a lubrication point for bearings and pivot joints on agricultural machinery. It is installed into threaded ports on the machine, and its angled head allows a grease gun coupler to reach the fitting in confined spaces where a straight nipple would be inaccessible. A worn or clogged nipple prevents grease from reaching the bearing surface, leading to accelerated wear in the joint. The 45-degree angle directs the grease flow into the bearing path. On installation, ensure the threads are clean and the nipple is tightened to a snug fit to prevent leakage.
