Push fit and compression fittings are two common types of pipe fittings used to join pipes or connect them to other components in plumbing systems. Both of these types of fittings have their advantages and disadvantages, and their suitability for a particular application depends on various factors. In this article, we will compare push fit pipe fittings to compression fittings, discussing their features, advantages, disadvantages, and applications.
Push fit pipe fittings
Push fit pipe fittings, also known as push to connect fittings, are designed to make joining pipes quick, easy, and reliable. These fittings consist of three main components : the body, the locking clip, and the sealing ring. The body is made of a durable material such as brass, stainless steel, or plastic, and it has a hollow center through which the pipe passes. The sealing ring is typically made of rubber or another flexible material, and it is located inside the body. The locking clip is used to secure the pipe in place once it is inserted into the body.
Push fit pipe fittings are known for their ease of installation. Unlike traditional fittings that require special tools and techniques to install, push fit fittings can be installed without any tools or special skills. To install a push fit fitting, all you need to do is insert the pipe into the fitting until it stops, and then push the locking clip into place. This creates a secure, leak free connection that can withstand high pressures and temperatures.
Push fit fittings have several advantages over other types of fittings. For one, they are easy to install and remove, which makes them ideal for situations where pipes need to be replaced or reconfigured frequently. They also provide a reliable seal that can prevent leaks, even in high pressure applications. Additionally, push fit fittings are available in a variety of sizes and materials, which makes them suitable for a wide range of applications.
However, push fit fittings also have some disadvantages. For one, they are typically more expensive than other types of fittings, which can be a concern for budget conscious plumbing projects. Additionally, push fit fittings may not be as durable as other types of fittings, especially in applications where they are exposed to high temperatures or corrosive materials.
Compression fittings
Compression fittings are another type of fitting used to join pipes or connect them to other components in plumbing systems. These fittings consist of three main components : the body, the compression ring, and the nut. The body is made of a durable material such as brass, stainless steel, or plastic, and it has a hollow center through which the pipe passes. The compression ring is typically made of brass or another metal, and it is located inside the body. The nut is used to compress the ring onto the pipe and create a tight seal.
Compression fittings are known for their durability and versatility. They are suitable for a wide range of applications, from low pressure systems to high pressure systems. They are also resistant to corrosion and can withstand high temperatures, making them ideal for use in harsh environments. Additionally, compression fittings are typically less expensive than push fit fittings, which can be a consideration for budget conscious projects.
However, compression fittings also have some disadvantages. For one, they can be more difficult to install than push fit fittings, as they require special tools and techniques to create a reliable seal. Additionally, compression fittings are more prone to leaks than push fit fittings, especially if they are not installed properly or if they are exposed to high pressures or temperatures. Finally, compression fittings can be difficult to remove once they are installed, which can be a concern in situations where pipes need to be replaced or reconfigured frequently.
Push fit fittings vs. Compression fittings : Applications
Push fit fittings and compression fittings both have their strengths and weaknesses, and their suitability for a particular application depends on various factors. Here are some examples of applications where each type of fitting might be preferred
Push fit fittings are commonly used in residential and commercial plumbing systems. They are ideal for situations where pipes need to be connected quickly and easily, such as in new construction or renovation projects. Push fit fittings can be used in both hot and cold water systems, and they are suitable for use with a variety of materials, including copper, PEX, and PVC. Some common applications for push fit fittings include :
Compression fittings are also commonly used in plumbing systems, especially in industrial or commercial applications where high pressures and temperatures are a concern. Compression fittings are ideal for situations where a reliable, leak free seal is critical, such as in gas supply lines or hydraulic systems. Some common applications for compression fittings include :

Conclusion
In conclusion, push fit fittings and compression fittings are both useful types of pipe fittings that have their own unique advantages and disadvantages. Push fit fittings are easy to install and provide a reliable, leak free seal, but they can be more expensive and may not be as durable as compression fittings. Compression fittings are durable, versatile, and suitable for use in high pressure systems, but they can be more difficult to install and may be more prone to leaks if not installed properly. The choice between these two types of fittings depends on the specific needs of the application, including factors such as pressure, temperature, and cost.
