Push fit pipe fittings and crimped fittings are two of the most popular types of pipe fittings used in various applications. Both of these fittings are widely used in plumbing, HVAC, and industrial piping systems, but they have different features and benefits. In this article, we will compare push fit pipe fittings and crimped fittings in detail.
Overview of Push Fit Pipe Fittings
Push fit pipe fittings are designed to join pipes without the need for any tools, soldering, or gluing. These fittings are made of high quality materials such as brass, copper, stainless steel, and plastic, which makes them durable and long lasting. They are available in a variety of shapes and sizes to fit different types of pipes, and they can be used with both copper and plastic pipes.
Push fit pipe fittings work by simply pushing the pipe into the fitting until it reaches the stop. The fitting has a rubber O ring or a silicone seal that creates a watertight and airtight seal between the pipe and the fitting. The O ring or seal also provides some flexibility, allowing the fitting to accommodate slight movements in the pipe.
Push fit pipe fittings have several advantages over traditional fittings. Firstly, they are easy to install and can be done quickly, even by DIY enthusiasts. Secondly, they do not require any special tools, soldering, or gluing, which reduces the risk of damage to the pipe or the fitting. Thirdly, they can be easily disassembled and reused, which is useful in situations where pipes need to be moved or replaced.
Overview of Crimped Fittings
Crimped fittings, also known as press fittings, are a type of pipe fitting that use a special tool to compress the fitting onto the pipe. The tool applies pressure to the fitting, which causes the fitting to deform and create a seal around the pipe. The pressure is typically around 3000 5000 psi, which ensures a tight and secure connection between the pipe and the fitting.
Crimped fittings are made of high quality materials such as stainless steel, copper, and brass, which makes them strong and durable. They are available in a variety of shapes and sizes to fit different types of pipes, and they can be used with both copper and plastic pipes.
Crimped fittings have several advantages over traditional fittings. Firstly, they provide a tight and secure connection that is leak proof and tamper proof. Secondly, they are easy to install and can be done quickly, even by DIY enthusiasts. Thirdly, they do not require any special tools, soldering, or gluing, which reduces the risk of damage to the pipe or the fitting.
Comparison of Push Fit Pipe Fittings and Crimped Fittings
Installation
One of the main advantages of push fit pipe fittings is that they are very easy to install. They can be installed quickly and easily, even by DIY enthusiasts. The installation process involves simply pushing the pipe into the fitting until it reaches the stop, and the O ring or seal creates a watertight and airtight seal. No special tools, soldering, or gluing is required.
Crimped fittings also have a relatively easy installation process. The fittings are compressed onto the pipe using a special tool, which creates a tight and secure connection. The installation process is quick and easy, but it requires a special tool, which can be expensive and may not be readily available.
Strength and Durability
Push fit pipe fittings are made of high quality materials such as brass, copper, stainless steel, and plastic, which makes them durable and long lasting. They are designed to withstand high temperatures, high pressures, and corrosive environments. However, push fit pipe fittings may not be as strong as crimped fittings, and they may not be suitable for certain applications where a higher level of strength is required.
Crimped fittings, on the other hand, are known for their strength and durability. They are made of high quality materials such as stainless steel, copper, and brass, which makes them strong and resistant to corrosion. They are designed to withstand high pressures and temperatures, and they provide a tamper proof and leak proof connection. Crimped fittings are suitable for a wide range of applications, including plumbing, HVAC, and industrial piping systems.
Leakage
Push fit pipe fittings provide a watertight and airtight seal, which reduces the risk of leaks. The O ring or seal creates a tight seal between the pipe and the fitting, which prevents water or air from escaping. However, push fit pipe fittings may not be suitable for applications where a higher level of pressure is required, as they may not be able to withstand the pressure.
Crimped fittings provide a tight and secure connection that is leak proof and tamper proof. The fitting is compressed onto the pipe, which creates a seal that is resistant to high pressures and temperatures. Crimped fittings are suitable for applications where a high level of pressure is required, such as in industrial piping systems.
Ease of Disassembly
Push fit pipe fittings can be easily disassembled and reused, which is useful in situations where pipes need to be moved or replaced. The fitting can be removed by using a simple tool or by pushing the release button, which allows the pipe to be pulled out of the fitting. The fitting can then be reused or replaced as needed.
Crimped fittings, on the other hand, are more difficult to disassemble. The fitting is compressed onto the pipe, which makes it difficult to remove without damaging the pipe or the fitting. In some cases, the fitting may need to be cut off, which can be time consuming and costly.
Cost
Push fit pipe fittings are generally less expensive than crimped fittings. They do not require any special tools, which reduces the overall cost of installation. They are also easy to install, which can save time and labor costs.
Crimped fittings are more expensive than push fit pipe fittings. They require a special tool, which can be expensive to purchase or rent. However, crimped fittings may be more cost effective in the long run, as they provide a secure and durable connection that requires minimal maintenance.
Conclusion
In summary, push fit pipe fittings and crimped fittings are both popular types of pipe fittings that offer unique benefits and advantages. Push fit pipe fittings are easy to install, do not require any special tools, and can be easily disassembled and reused. Crimped fittings provide a tight and secure connection that is resistant to high pressures and temperatures, and they are suitable for a wide range of applications.
The choice between push fit pipe fittings and crimped fittings will depend on the specific needs of the application. Push fit pipe fittings are ideal for applications where a simple and quick installation is required, while crimped fittings are suitable for applications where a higher level of strength and durability is required. Cost is also a factor to consider, as push fit pipe fittings are generally less expensive than crimped fittings. Ultimately, the decision between push fit pipe fittings and crimped fittings will depend on the specific needs and requirements of the application.
