Exploring Common Types of Plumbing Fittings

When it comes to plumbing systems, the unsung heroes are often the fittings that connect pipes and ensure a leak-free, efficient flow of water or gas. Plumbing fittings come in various shapes and sizes, each serving a unique purpose. In this blog post, we will delve into four common types of plumbing fittings: compression fittings, copper fittings, solder ring fittings, and end feed fittings, exploring their features, uses, and advantages.

Compression Fittings

Compression fittings are known for their simplicity and ease of installation. These fittings consist of three main components: a compression nut, a compression ring (also known as a ferrule), and the fitting body. The principle behind a compression fitting is that when the nut is tightened, it compresses the ring onto the pipe, creating a watertight seal. Compression fittings are ideal for connecting pipes made of various materials, such as copper, plastic, or stainless steel.


  • No soldering or specialised tools are required for installation.
  • Reusable: They can be disassembled and reassembled without damaging the components.
  • Suitable for DIY projects due to their straightforward installation process.
  • Versatile: Can be used for both water and gas pipes.

Copper Pipe Fittings

Copper Pipe fittings have been a staple in plumbing for decades due to their durability, reliability, and excellent heat and corrosion resistance. These fittings are often used in both residential and commercial plumbing systems. Copper fittings come in various shapes, including elbows, tees, couplings, and reducers, allowing for versatile plumbing designs.


  • Longevity: Copper fittings have a long lifespan and can withstand the test of time.
  • Suitable for high-temperature applications, making them ideal for both hot and cold water systems.
  • Resistant to corrosion, ensuring a consistent flow of water over the years.
  • Can be soldered, brazed, or even connected using compression fittings.

Solder Ring Fittings

Solder ring fittings, also known as pre-soldered fittings, offer a convenient and efficient solution for joining copper pipes. These fittings have a ring of solder already applied to the inside, which melts and forms a secure bond when heat is applied during the installation process. Solder ring fittings are particularly favoured by professionals for their speed and reliability.


  • Speed: The pre-soldered feature reduces the time needed for soldering, increasing work efficiency.
  • Clean and neat joints: The solder is evenly distributed, creating a strong and leak-free connection.
  • Suitable for situations where soldering might be challenging, such as tight spaces.

End Feed Fittings

End feed fittings, also known as capillary fittings, are commonly used in copper pipe installations. These fittings consist of a body with a tapered opening. During installation, the pipe end is inserted into the fitting until it reaches a stop, ensuring a secure connection. Solder is then applied to the joint, creating a robust bond.


  • Strong and reliable joints: The soldered connection ensures minimal risk of leaks.
  • Versatile: End feed fittings are available in a wide range of configurations to suit various plumbing needs.
  • Suitable for both new installations and repair work.


Plumbing fittings play a crucial role in maintaining the integrity of plumbing systems, and different types cater to various needs and preferences. Whether you’re a DIY enthusiast or a professional plumber, understanding the characteristics and benefits of compression fittings, copper fittings, solder ring fittings, and end feed fittings can empower you to make informed decisions when working on plumbing projects. By choosing the right fitting for the job, you can ensure a plumbing system that is not only functional but also durable and reliable over time.
