Pros and Cons of Different Materials Used in Pipe Fittings

Date:July 11, 2023

When it comes to pipe fittings, it’s important that you check the material they are made of. It’s said that the material of the pipe fittings defines the longevity and efficiency of the plumbing system. But, the question is which material to choose as all of them comes with different features, advantages, and limitations.

In this post, we will discuss the common material used in pipe fittings and their pro and cons. This will help you take the right decision.

PVC (Polyvinyl Chloride)

PVC, or polyvinyl chloride, is gaining popularity among homeowners. It is a thermoplastic polymer that softens at high temperatures but remains rigid at normal temperatures. PVC offers longevity due to its rust and corrosion resistance. It can handle high pressure, making it ideal for main supply lines. PVC is lightweight, easy to install with glue, and cost-effective. However, it is not suitable for hot water and has limited sizing options, with bulky fittings for tight spaces.


Copper remains a popular choice for plumbing pipes due to its longevity, durability, safety, recyclability, and temperature tolerance. With a lifespan of at least 50 years, copper pipes resist leaks and corrosion. They are also bacteria-resistant, ensuring safe drinking water. When replaced, copper can be recycled. However, the high financial cost of copper and environmental concerns related to mining and manufacturing make it less environmentally friendly.

Stainless Steel

Despite being more costly than copper piping, stainless steel piping offers exceptional quality. Stainless steel is strong and corrosion resistance. So, it is commonly used in coastal communities or areas that are prone to corrosion. Stainless steel pipes come in both flexible and rigid options, available in various sizes. Couplings are used to connect the pipes securely.


Brass pipe fittings are known for corrosion resistance, robustness, and adaptability. They have numerous applications, including plumbing, heating, and industrial systems. Because they can be threaded or soldered, brass fittings are simple to install. They are also good conductors and can be used in hot water applications. However, because brass fittings may contain lead, it is critical to check that they meet current norms and standards.

PEX (Cross-linked Polyethylene)

Cross-Linked Polyethylene (PEX) is a popular plastic material for plumbing. It offers longevity, being rust and corrosion-resistant, and can last indefinitely unless broken. PEX is flexible, making it easy to navigate turns and retrofit houses with long pieces. Installation is simple without the need for soldering or gluing. It can withstand extreme temperatures, suitable for both hot and cold water transport. But, it is not suitable for outdoor use due to UV radiation damage and may affect water taste and odor if stagnant.


The material you use for pipe fittings is critical to the overall performance and lifespan of your plumbing system. You may choose the best material for your unique needs by taking into account elements such as cost, corrosion resistance, temperature constraints, and installation requirements. Consulting with plumbing professionals and sticking to industry standards can help to assure the dependability and efficiency of your pipe fittings for many years.
