Compression fittings are a bit more involved than quick-connect fittings, as they require you to thread the tubing through a compression sleeve before securing it with clamps. The compression sleeve will create a tight seal, while the clamps will secure it. Compression fittings are typically used with copper or PVC tubing and come in various sizes. Compression fittings are best used when you want a very tight seal, but you don’t want to use a clamshell style fitting because of the need for high pressure. Compression fittings, like most other types, come in various materials, including brass, stainless steel, and PVC. The majority of sleeves are made of PVC. When choosing a compression fitting, ensure that you have a nut compatible with your sleeve. Most compression nuts are made of either lead or brass, but you can also find stainless steel,plastic compression nuts.
What is a compression fitting?
Compression fittings are a strong and durable way to connect tubing in applications where pressure changes are likely to occur. Working with metals and plastics or aggressive fluids can create intense temperature, and pressure ranges during operation. The strength and durability of compression fittings are due to the forces involved when connecting or disconnecting the fittings. As the ferrule(s) is pushed into the body, any wobble in the ferrule will be reduced. This, combined with the radial compression applied by the body on the ferrule as it travels into the fitting, makes compression fittings extremely reliable. Much like their counterparts, compression fitting can have a variety of applications. These include applications where the pressure must be extremely high, temperature or chemical compound compatibility is essential, or a specific tight-fitting application needs to be maintained. Compact, lightweight, and sealed systems require high pressure, and compression fittings are the best choice for such applications. In these types of applications, compression fittings are a great choice. Compression fittings are an excellent choice for applications where a specific tight-fitting application is essential. They can eliminate the need for clamps and provide an easier-to-install solution.
What are compression fittings made from?
Compression fittings are made from many different materials like brass, copper, plastic, and cast iron. Plastic compression fittings are commonly used in commercial settings because they are lightweight and easy to install. Brass compression fittings are most widely used in residential settings because they are durable and corrosion-resistant. Copper compression fittings offer corrosion resistance while also being lightweight. Cast iron is the most common material in compression fittings because it offers corrosion resistance while being heavy duty and durable.
Installing and removing compression fittings: how do you do it?
Compression fittings are a simple way to connect to your water supply and keep the work of water in your pipelines smooth. They can be installed in several different ways, depending on the purpose.
- Unlike threaded fittings, water compression fittings have a nut on both ends (one end fits onto the tubing, the other onto a fitting). The nut allows you to tighten the compression fitting onto the tubing, creating more pressure and holding the seal.
- Then make sure that the sleeve faces the nut side so it can be pierced easily. Now push the sleeve up until it hits the nut. Make sure that it is aligned correctly, or else the sleeve might get pierced into the nut side rather than the threaded side.
- Ensure that the sleeve is flush with the nut before you tighten it. This will help to prevent fresh water from leaking through the joint. With the nut tight and the sleeve in place, slide the o-ring over the sleeve and then push the connector into the tubing.
- Secure the nut with a spanner. Then fix the sleeve with a set screw.
- When tightening your compression fittings, ensure you use the correct torque for your specific fitting. If you are unsure, consult the manufacturer’s instructions. You will likely need a socket wrench for this.
It is important to remember that compression fittings require a specific nut and sleeve pair. You risk ruining the connection if you select the wrong nut and sleeve. Additionally, you must ensure that your tubing is adequately secured in the connector. If it comes loose during the process, you risk ruining the connection.
Removal process –
The same procedure used for metal compression fittings is applied to plastic ones, and the job is usually easier. To remove a plastic fitting, you must use two locking pliers: one to turn the compression nut and the other to keep the pipe from turning. Turn the compression nut counterclockwise with one pair of locking pliers while holding the pipe steady. It may take more effort to unlock the compression nut and turn it than you anticipate, but it is never as much work as unlocking a metal fitting. Once the nut turns, you may be able to remove it by hand to separate the fitting, so all that remains is to remove the ferrule from the pipe.
Ferrule removal –
Compression ring pullers are used to remove a ferrule, also known as a compression ring. A metal ferrule bonded to the pipe can be hard to remove, so a compression ring puller is necessary. It would help if you used your fingers to remove a compression ring on a plastic compression fitting, as plastic or rubber rings do not weld. After you separate the fitting, grip the compression ring and pull it toward the end of the pipe with your fingers. It may be difficult to remove, so turn it in one direction while pulling it. Try pulling and twisting it until it starts to move. Once it starts to move, use a combination of pulling and twisting motions to coax it off the end of the pipe.
