This 90-degree grease nipple delivers lubricant to bearings and pivot points that are not directly accessible from a straight fitting. It is installed into threaded lubrication ports on the host machine, redirecting the grease path by a right angle so the coupler can reach the zerk without interference from surrounding structures. The M10x1 thread matches the standard port used on many agricultural implement and tractor assemblies. A worn or clogged nipple prevents grease from reaching the bearing, leading to accelerated wear and eventual seizure of the joint. This component is manufactured to the original thread pitch and seating angle so it seals properly in the port without leaking grease under pressure.
