Angel Light Industry(Suzhou) Co.,Ltd.

We produce grease fittings, also known as Zerk fittings or grease nipples, are small mechanical components used in lubrication systems to allow the injection of grease or lubricant into bearings, joints, or other moving parts of machinery.
These fittings are essential for maintaining smooth operation and reducing wear and tear on mechanical components by ensuring proper lubrication in hard-to-reach areas.

These grease fittings typically have a ball check valve that prevents dirt or contaminants from entering the system while allowing grease to be pumped in using a grease gun. They are commonly used in automotive, industrial, agricultural, and other heavy-duty machinery applications.
