5-Pack 304 Stainless Steel Straight Grease Nipple, M8 x 1mm Hydraulic Fitting for Automotive, Agricultural, and Industrial Machinery

【Straight‑Through Design】The low‑profile straight‑through design allows this hydraulic grease nipple to be installed in tight spaces such as engine bays, suspension links, and mechanical joints. The streamlined shape ensures lubrication access without interference from surrounding components. 【Easy Injection】The threads on the grease nipple are clean and deep, enabling smooth injection of mechanical lubricant to keep moving parts well‑lubricated. 【Wide Application】Suitable for industrial machinery and facilities, marine equipment, tractors, machine tools, motorcycles, cars, trucks, and agricultural machinery. 【Quality Material】Made of high‑quality 304 stainless steel, offering excellent rust resistance, oxidation resistance, and chemical corrosion resistance. The dense surface maintains structural integrity and stable performance over long‑term use. 【Secure Installation】When screwed into the corresponding port, it forms a tight self‑sealing interface with progressive clamping force during installation. This eliminates the need for thread sealant while preventing leakage or side oil seepage.
