Selecting the appropriate pipe material is key when embarking on any plumbing project to ensure longevity and efficiency within your system. With so many options today, choosing the right type that fits your requirements can be daunting. This blog post will discuss various plumbing pipe materials and their applications, highlighting Oatey products that can assist you in your plumbing tasks.
1. PEX
PEX plumbing pipes are commonly used in new-home constructions due to their flexibility and resistance to freezing temperatures. You can choose PEX for projects such as installing water lines for bathrooms or kitchens, radiant floor heating systems, or outdoor sprinkler systems.
There are two main types: Cold expansion PEX, or PEX-a, and PEX-b. Cold expansion PEX requires an expansion tool for fitting connections, while PEX-b utilizes crimp rings. These pipes are easy to install and cost-effective.
Having the right products is important to ensure optimal installation and performance of your PEX plumbing system. These products include supply boxes compatible with PEX piping and hammer arrestors with PEX Connection that absorb shock and prevent water hammer.
2. Brass
Brass pipes are a premium choice known for their durability and aesthetic appeal. Installers may opt for brass pipes when working on projects like exposed plumbing in bathrooms or kitchens, outdoor water features, or decorative piping for shelves or furniture. While brass pipes come at a higher price point than other materials, they offer long-term reliability and corrosion resistance.
When selecting brass tubular products, be sure to consider the available thickness options. Once again, thicker products will be more expensive but also more durable. For residential projects, 20- or 22-gauge brass products are typically suitable.

3. CPVC
CPVC plumbing pipes offer a cost-effective solution for plumbing projects. They are easy to install without requiring specialized tools, making them suitable for creating water supply lines in sinks, toilets, or laundry rooms. With excellent corrosion-resistance properties, CPVC pipes are commonly used in residential water distribution systems.
Orange Lava Cement can be used to bond CPVC pipes and fittings securely. This cement reduces cure time, making it great for cut-in or quick pressurization.
Additionally, there are stops and supply lines compatible with CPVC systems, allowing for convenient shutoff and control of water flow.
4. Galvanized and Black Iron
Once a popular choice, galvanized plumbing pipes have fallen out of favor due to their tendency to corrode over time.
However, black iron pipes are known for their strength and durability, making them a common choice for gas supply rather than water supply. They excel in high-pressure conditions, guaranteeing a reliable and secure gas supply, making them ideal for stoves, fireplaces, or outdoor grills.
For added stability, installers can depend on Oatey's pipe support systems specifically designed for these pipes. Oatey offers a cutting oil that provides lubrication, enhances precision, and extends the lifespan of tools to simplify the process of cutting and threading galvanized and black iron pipes.
5. Copper
Copper plumbing pipes are esteemed for their longevity and reliability, making them a favored choice for plumbing projects that require a durable solution. These pipes are particularly suitable for hot- and cold-water supply lines and refrigerant lines in HVAC systems. With their corrosion resistance, ability to withstand high temperatures, and inhibiting effect on bacteria growth, copper plumbing pipes are a worthwhile investment for long-term projects.
To achieve secure and long-lasting soldered connections of copper pipe, Oatey® 95/5 Lead-Free Plumbing Wire Solder is recommended. This tin-antimony formula is specially designed for plumbing applications that frequently experience extreme temperature changes and vibrations.
For optimal adhesion and strong joints, consider using Oatey® H-20® 95 Water Soluble Tinning Flux to aid the soldering process.
6. Cast Iron
Cast iron pipes are known for their quiet operation and exceptional durability, making them a reliable choice for plumbing systems. While heavier and requiring specialized equipment for installation compared with contemporary plastic piping systems, cast iron pipes are ideal for homeowners seeking a traditional, reliable, and durable plumbing material when renovating older properties or prioritizing longevity over ease of installation.
For sealing and caulking needs, Oatey Hercules Plastic Seal™ is a high-quality, multi-purpose polyurethane sealant suitable for various applications, such as repairing old cast iron soil pipe joints. It offers an excellent lead substitute for caulking, creating a reliable and long-lasting seal.
7. ABS and PVC
Due to their versatility, ABS and PVC pipes are commonly used in residential plumbing projects. These plastic pipes are ideal for drain waste and vent (DWV) systems, offering lightweight construction and excellent chemical resistance. Consider these cost-effective options for the following applications:
- Installing a new sink in the kitchen or bathroom
- Building a custom irrigation system for your garden
- Constructing a rainwater harvesting system
- Setting up a simple outdoor shower
- Creating a homemade hydroponic gardening setup
ABS or PVC cement can create permanent bonds between pipes and fittings to ensure secure connections. Additionally, using pipe supports will prevent sagging and shifting when installing pipes, guaranteeing reliable and long-lasting connections.
By understanding the characteristics of each type — from flexible PEX to durable brass or cost-effective CPVC — you can make an informed decision tailored to your specific requirements. Consider factors like durability, ease of installation, corrosion resistance, and cost-effectiveness when choosing materials like ABS or PVC versus cast iron or galvanized steel options based on your project’s unique needs.
Whether you're working on a minor repair or a large-scale renovation project, understanding the different types of plumbing pipe materials and handy Oatey products will ensure success in all your future plumbing endeavors!
