deep access lubrication fitting

Our brass extended grease nipples feature an extra-long threaded design to reach deep, recessed lubrication points that standard-length nipples cannot access. Available in straight, 45°, and 90° angles, they are precision-engineered from high-purity H62 brass for excellent corrosion resistance and durability. Ideal for heavy machinery, construction equipment, and industrial applications, these long-thread grease fittings ensure reliable lubrication delivery to hard-to-reach bearings and joints.
