Fittings play a crucial role in maintaining lubrication and ensuring the proper functioning of mechanical systems. Grease fittings, also known as Zerk fittings, are essential for delivering lubrication directly to bearing points. Other fittings include connectors and adapters tailored to specific equipment requirements, ensuring optimal lubrication, alignment, and secure connections. By providing a seamless flow of lubricants, fittings reduce friction, minimize wear, and prolong equipment life.
