Brass vs. PVC: A Material Comparison

Both brass and PVC offer unique features and benefits when used in NPT female union elbows.

Durability and Strength

Brass is known for its high strength and durability. It withstands high-pressure situations and extreme temperatures, making it ideal for hot water systems and outdoor installations. In contrast, PVC is lightweight and resistant to corrosion but may not perform well under high pressures or extreme temperatures.

Cost-Effectiveness

When it comes to pricing, PVC is the more budget-friendly option. It is generally less expensive than brass, making it a popular choice for homeowners and small projects. However, brass's longevity and durability can offset its higher initial cost in the long run.

Installation and Maintenance

PVC is easier to install, requiring no specialized tools or techniques, which is why many DIY enthusiasts prefer it. Brass fittings, while more complex to install, may require professional assistance, especially in high-stress applications.

Resistance to Environmental Factors

Brass has excellent resistance to environmental factors such as UV radiation and extreme weather, making it suitable for outdoor applications. PVC may become brittle over time when exposed to UV light, limiting its outdoor use without protective measures.
