A 4-way fitting, also known as a cross fitting, is a type of pipe fitting that allows four pipes to be connected at a cross intersection. It is typically used in plumbing and industrial applications where four pipes need to be joined together to allow for the flow of fluids or gases in multiple directions.
4-way fittings come in a variety of materials including PVC, copper, steel, and brass, and are available in different sizes to accommodate various pipe diameters. They are commonly used in applications such as water distribution systems, irrigation systems, and pneumatic systems.
4-way fittings are available in different configurations, including:
Standard 4-way fitting: A standard 4-way fitting has four openings of equal size and is used to join four pipes of the same diameter.
Reducing 4-way fitting: A reducing 4-way fitting has four openings of different sizes, allowing for the connection of four pipes of different diameters.
Cross 4-way fitting: A cross 4-way fitting has four openings, with two openings on the top and two openings on the sides, 4 way fitting supplier forming a cross shape. Cross 4-way fittings are used to join four pipes at a cross intersection.
4-way fittings can be secured to the pipes using various methods, including soldering, welding, or threading, depending on the material and application. It is important to choose the correct type and size of 4-way fitting for your specific application to ensure a tight and secure connection.
Overall, 4-way fittings are an essential component of piping systems, allowing for the flow of fluids or gases in multiple directions. It is important to select the appropriate 4-way fitting for your specific application based on the material, configuration, and method for securing it to the pipes.
When selecting a 4-way fitting for a pneumatic system, it is important to choose a fitting that is designed for use with compressed air and can withstand the high pressures and vibrations associated with pneumatic applications.
Here are two types of 4-way fittings that are commonly used in pneumatic systems:
Brass 4-way fitting: Brass fittings are commonly used in pneumatic systems because brass is durable, corrosion-resistant, and can withstand high pressures. Brass 4-way fittings are available in various sizes and configurations, and can be secured to the pipes using compression fittings or threads.
Polymer 4-way fitting: Polymer or plastic fittings are also commonly used in pneumatic systems because they are lightweight, corrosion-resistant, and can withstand high pressures. Polymer 4-way fittings are available in various sizes and configurations, and can be secured to the pipes using compression fittings or push-to-connect fittings.
It is important to choose a 4-way fitting that is compatible with the specific type of piping material used in the pneumatic system, as well as the required pressure rating and flow rate. It is also important to ensure that the fitting is properly installed and secured to the pipes to prevent leaks or other issues. It is recommended to consult with a pneumatic system expert or the manufacturer of the system to ensure that the appropriate type of 4-way fitting is selected for the specific application.
