Compression union

Compression fittings are an essential component in plumbing and piping systems. These fittings provide a secure and leak-proof connection between pipes or tubes, making them ideal for a wide range of applications in the transportation of water, gas, and other liquids. Compression fittings come in various types, such as unions, tees, and couplings, and they can be made with National Pipe Taper (NPT) threads for added reliability. In this article, we will explore the basics of compression fittings, including the different types, the measurement system used for sizing, and the advantages of using compression fittings in plumbing and piping systems.

What is a compression union?

A compression union is a plumbing fitting used to connect two pipes or tubes and provide a disconnection point. It consists of three pieces: a nut, a female end, and a male end. The male end fits inside the female end, and the nut is tightened over both to create a leak-proof seal. This design allows for easy installation and provides a secure connection between pipes or tubes.

Compression unions are commonly used in pipes carrying water or gas, and they are known for their reliability and ease of installation. The use of a compression union in a piping system allows for maintenance or repairs to be made without having to shut off the entire system. Simply loosen the nut, disconnect the pipes or tubes, and then reattach them when the work is complete.

Compression unions are available in a range of sizes, and they can be manufactured with NPT threads for added security and reliability. Additionally, compression unions are compatible with a wide range of pipes and tubes, including metal, plastic, and rubber.

In summary, a compression union is a plumbing fitting used to connect two pipes or tubes and provide a disconnection point. It is reliable, easy to install, and provides a secure connection between pipes or tubes.

What is a compression tee?

A compression tee is a type of plumbing fitting used to connect three pipes or tubes at a single point. It consists of a body with three openings – two female ends and one male end – and three nuts. The male end fits inside one of the female ends, while the other two female ends fit over the ends of two separate pipes or tubes. The nuts are tightened over each end to create a leak-proof seal.

Compression tees are commonly used in piping systems to branch off a main line and allow for the connection of additional pipes or tubes. They provide a secure and reliable connection, and the use of nuts allows for easy installation and maintenance. Compression tees are available in a range of sizes and can be manufactured with NPT threads for added security and reliability.

In summary, a compression tee is a plumbing fitting used to connect three pipes or tubes at a single point. It provides a secure and reliable connection and allows for easy installation and maintenance. Compression tees are available in a range of sizes and can be manufactured with NPT threads for added security and reliability.

Are compression fittings OD or ID?

Compression fittings are designed to fit over the outside diameter (OD) of pipes or tubes. The male end of a compression fitting has an outside diameter that fits snugly over the pipe, and the female end has an inside diameter that fits over the male end. This allows for a secure and leak-proof connection to be made without the need for additional sealing compounds or tapes. The outside diameter measurement of pipes and tubes is a standardized measurement, making it easier to select the appropriate size compression fitting for a given application. In summary, compression fittings are designed to fit over the outside diameter (OD) of pipes and tubes.

Are compression fittings NPT?

Compression fittings can be manufactured with National Pipe Taper (NPT) threads, which are a type of thread commonly used in North America for plumbing and piping applications. NPT threads are tapered and provide a tight, leak-proof seal when used with a sealing compound. The use of NPT threads on compression fittings adds a level of security and reliability, ensuring that the connection between pipes and tubes remains tight over time.

Compression fittings with NPT threads are commonly used in gas and water supply pipes, as well as in other applications where a leak-proof seal is essential. NPT threads are available in a range of sizes, making it easy to select the appropriate size for a given application. Additionally, NPT threads are compatible with a wide range of pipes and tubes, including metal, plastic, and rubber.

In summary, compression fittings can be manufactured with NPT threads, providing a tight, leak-proof seal and adding a level of security and reliability to plumbing and piping systems.

In conclusion, compression fittings are a versatile and reliable option for connecting pipes and tubes in plumbing and piping systems. With the ability to connect multiple pipes or tubes and the ease of installation, compression fittings are a popular choice for many applications. Additionally, the use of NPT threads provides a tight, leak-proof seal, making them suitable for transporting liquids and gases. Whether you’re installing a new plumbing system or making repairs, it’s important to consider the benefits of compression fittings and choose the right type and size for your project.
