There are numerous types of plumbing fittings, each with its unique purpose and application. Some of the most common fittings include:
Adapters are used to connect two different types of pipes or fittings. They come in various sizes and shapes, ensuring a secure connection between different materials or pipe sizes.
Couplings are used to connect two similar pipes or extend the length of a pipe. They come in two forms: regular and slip. Regular couplings have a central ridge that stops the pipe from sliding through, while slip couplings have a smooth interior that allows the pipe to slide in for easier installation.
Elbow fittings change the direction of a pipe, usually at 45 or 90-degree angles. They are used in both water supply lines and drainage systems to navigate around obstacles and corners.
Tee fittings have three openings and are used to create branch lines or split a single pipe into two separate lines. They come in various sizes and angles to accommodate different pipe configurations.
Cross fittings have four openings, allowing for the connection of four pipes at a single point. They are typically used in sprinkler systems and other applications that require multiple pipe connections.
Caps are used to close off the end of a pipe, preventing water or waste from escaping. They are commonly used during plumbing repairs or when a pipe is temporarily not in use.
Plugs are similar to caps but are used to close off the end of a threaded pipe. They are available in a variety of materials and sizes to accommodate different pipe diameters.
Nipples are short lengths of pipe with threads on both ends, used to connect two fittings or extend the length of a pipe. They are available in various materials and lengths.
Union fittings are used to join two pipes without the need for soldering or threading. They consist of three parts: a nut, a female end, and a male end. When the nut is tightened, the male and female ends are compressed together, creating a watertight seal.
Valves are used to control the flow of water or gas through a pipe. They come in a variety of types, including ball valves, gate valves, and check valves, each with its specific purpose and application.
