COMPRESSION FITTINGS Manufacturers

INDUSTRY & KNOWLEDGE

What are the functions of compression fittings and what are the precautions for use?
Compression fittings are mechanical devices used to join two or more pipes or tubes in plumbing, gas, hydraulic, or pneumatic systems. They consist of a nut, a compression ring (or ferrule), and a body that holds the components in place. The main functions and precautions for use are as follows:

Functions of Compression Fittings:
Sealing: Compression fittings create a tight seal between pipes or tubes, preventing leaks of liquids or gases. The compression ring is squeezed as the nut is tightened, creating a secure connection.
Connecting Pipes/Tubes: They provide a secure way to connect two pipes or tubes without the need for welding, soldering, or threading. They are often used when the pipes need to be disassembled or replaced.
Adaptability: These fittings can be used for both metal and plastic pipes, providing flexibility in installation. They are often used in applications involving water, gas, and various chemicals.
No Need for Heat or Special Tools: Unlike other types of connections, compression fittings do not require heat or specialized equipment to make a secure connection. This makes them easy to use for DIY projects and in situations where the use of welding or soldering isn't feasible.
Vibration Resistance: Compression fittings can withstand vibrations and movements, making them ideal for use in applications like automotive, HVAC systems, and machinery where parts are in motion.

Precautions for Use:
Proper Tightening: Over-tightening the compression nut can damage the fitting and cause leaks, while under-tightening can result in a loose connection. It's important to tighten the nut firmly but not excessively. Follow the manufacturer’s recommended torque settings.
Clean Pipe Ends: Before installation, make sure the pipe ends are clean and free of debris, dirt, or corrosion. Contaminants can prevent a proper seal and lead to leaks.
Avoid Overuse of Thread Sealants: Compression fittings generally do not require thread sealants, as the seal is created through the compression of the ring. Using sealant can interfere with the fitting's ability to seal properly.
Check the Condition of the Ferrule: The compression ring (or ferrule) should be in good condition. A damaged or worn ferrule may not compress properly and could cause leaks. Always replace the ferrule if it's damaged or shows signs of wear.
Do Not Overstretch: Do not bend the pipe excessively before or after installation, as this can put undue stress on the compression fitting and cause it to fail.
