Product Description

GANT Compression fittings are made of durable brassalloy-CW617N.Specially selected NBR sealing rings ensure long-term functionality and leak-tightness,The fittings feature a double sealing solutionemplovine O-rinesand an additional Tefl on washer at the point where aluminium layer contacts the fitting material,which protects against electrochemical corrosion.The construction of the nozzle and the internal surface of the compression sleeve ensure fi rm pipe fitpreventing it from sliding out during use.

PEX Compression Fittings 
PEX Compression Fittings are plumbing fittings commonly used in plumbing and heating systems. Unlike other fittings, it uses a ferrule-style design that allows easy connection and    removal of pipes without the use of specialized tools or skills.


1. Easy to install and disassemble: ferrule-type design, you can easily connect the pipes  together without using professional tools or skills. It is also easy to disassemble for easy maintenance.  
2. High durability: Because the brass material has good corrosion resistance, it can be used for    a long time without rust or corrosion, prolonging the life of the joint and reducing replacement costs.    

3. Wide applicability: suitable for various piping systems, such as cold water, hot water, heating and water supply systems. Its material is strong, can withstand high temperature and    high pressure, and is suitable for various complex environments.    

4. High safety: The design of the joint can ensure that the pipe connection is firm and not easy  to leak or break. This increases the safety of the piping system and reduces possible  accidents and injuries.

Identifying Leaks or Improper Sealing in a Compression Coupling

Compression couplings are designed to create a tight and secure seal between pipes. However, leaks or improper sealing can still occur. Here are signs to watch for and steps to address them:

  • Water Dripping: If you notice water dripping from the coupling joint, it’s a clear sign of a leak. Inspect the area closely to identify the source of the leak.
  • Pooling Water: Pools of water forming around the coupling can indicate a leak. This can lead to water damage and should be addressed promptly.
  • Water Stains: Water stains on nearby surfaces can be a result of a slow leak from the coupling. Check for discoloration or dampness.
  • Reduced Water Pressure: Leaks can lead to a decrease in water pressure in the affected area. If you experience sudden pressure drops, inspect the couplings for leaks.
  • Audible Hissing or Whistling: Sometimes, leaks can produce a hissing or whistling sound. Listen carefully near the coupling to detect any unusual noises.

If you suspect a leak or improper sealing in a compression coupling, here’s what you can do:

  • Tighten the Coupling: If the coupling is slightly loose, use a wrench to gently tighten it. Avoid over-tightening, as it could damage the coupling or pipes.
  • Check the O-Ring or Gasket: Compression couplings often use rubber O-rings or gaskets for sealing. Inspect these components for damage or wear. Replace them if necessary.
  • Inspect Pipe Ends: Ensure that the pipe ends are clean, smooth, and free from debris. Rough or uneven pipe ends can prevent a proper seal.
  • Reassemble and Test: Disassemble the coupling, inspect all parts, and reassemble it carefully. Turn on the water supply and monitor for any signs of leakage.
  • Consider Professional Help: If leaks persist or you’re unsure about addressing the issue, it’s recommended to seek assistance from a professional plumber.

Regular inspection and maintenance of compression couplings can help prevent leaks and ensure the proper functioning of plumbing systems.

Recent Advancements in Compression Coupling Technology

Compression coupling technology has evolved over the years to offer improved performance, ease of use, and durability. Some recent advancements include:

  • Advanced Materials: Manufacturers are using innovative materials that offer better resistance to corrosion, chemicals, and extreme temperatures. These materials contribute to the longevity and reliability of compression couplings.
  • Enhanced Sealing Mechanisms: New designs of compression couplings feature enhanced sealing mechanisms, such as double O-rings or gaskets, to provide superior leak prevention and improved sealing under varying conditions.
  • Quick Installation Systems: Some compression couplings now incorporate quick installation systems that eliminate the need for special tools or excessive tightening. These systems improve installation efficiency and reduce the risk of over-tightening.
  • Leak Detection Technology: Certain compression couplings are equipped with leak detection features. These technologies provide visual or audible signals when a leak is detected, allowing for early intervention and preventing water damage.
  • Compatibility with Various Pipe Materials: Advancements have been made in designing compression couplings that are compatible with a wide range of pipe materials, including copper, PEX, PVC, and more. This flexibility enhances their applicability.

These advancements aim to address common challenges associated with compression couplings and enhance their overall performance, reliability, and ease of installation. As technology continues to progress, we can expect further innovations that optimize plumbing and piping systems.

Factors to Consider When Selecting a Compression Coupling

Choosing the right compression coupling for a specific application involves considering several factors to ensure a proper and reliable connection:

  • Pipe Material: Different compression couplings are designed to work with specific pipe materials, such as copper, PVC, PEX, or steel. Ensure the coupling material is compatible with the pipes you’re joining.
  • Pipe Size: Compression couplings come in various sizes to accommodate different pipe diameters. Choose a coupling size that matches the pipe size.
  • Application: Consider the type of application, whether it’s for plumbing, irrigation, or other systems. The coupling should be suitable for the intended use.
  • Pressure Rating: Check the pressure rating of the coupling to ensure it can handle the maximum pressure of the system it’s being used in.
  • Temperature Range: Consider the temperature range of the system. Some couplings are designed for use with hot water, while others are not suitable for high temperatures.
  • Compatibility: Ensure that the compression coupling is compatible with any existing pipes, fittings, or components in the system.
  • Installation: Evaluate the ease of installation. Some couplings require special tools, while others can be tightened using basic tools.
  • Seal Reliability: Look for couplings that provide a secure and leak-resistant seal. The design of the compression rings or inserts should ensure a watertight connection.
  • Corrosion Resistance: If the system will be exposed to moisture or corrosive substances, choose a coupling that is resistant to corrosion.
  • Brand and Quality: Opt for reputable brands known for producing high-quality couplings that adhere to industry standards.

By considering these factors, you can select a compression coupling that meets the requirements of your specific application and ensures a durable and effective pipe connection.
