Grease fittings are used to connect different parts of a bicycle, often in difficult-to-reach places. They come in various sizes and shapes and can be screwed onto the ends of tubes or posts. Grease fittings allow you to change the position of a part on your bike easily, which is useful if you want to adjust something like the saddle height or handlebars.

Types of grease fittings
Grease fittings are an important part of bicycle maintenance and repairs. There are a variety of types of grease fittings, so it's important to know what is available to you.
Pipe grease fittings: Pipe grease fittings are the most common type and are used on bicycles that use threaded joints. They connect the pipe or tube that carries grease to the bike's moving parts.
Tube-type grease fittings: Tube-type grease fittings are also common and connect tubing to bicycle components with threaded joints. They usually have one male thread and one female thread, but there are also two-threaded versions available for even more versatility.
Plug-style grease fittings: Plug-style grease fittings are designed for use with engines that don't have threaded joints. They connect tubing to an engine block or carburetor with a hose clamp or connector.
