Grease Fittings
also known as Zerk fittings or lubrication nipples, are high-quality components used for injecting lubricants into mechanical systems under pressure. They provide a secure and leak-proof point for connecting a grease gun, ensuring that grease reaches internal bearing surfaces, bushings, and moving joints effectively.
Designed in accordance with global standards like DIN, SAE J534, and ISO 4570, Metalok grease fittings are available in various designs including straight, 45°, 90° angles, button head types, and flush-style fittings. These fittings are manufactured using durable materials like carbon steel, stainless steel (SS316), and brass, with optional zinc or nickel plating for corrosion resistance in harsh environments.
