SCH 80 PVC fittings are commonly used in high-pressure and industrial piping systems. With thicker walls than SCH 40, they are better suited for applications that demand strength, durability, and chemical resistance. LESSO America manufactures a wide selection of SCH 80 PVC fittings that meet stringent performance standards and are used across various industries, including chemical processing, water treatment, and manufacturing.

How SCH 80 PVC Fitting Sizes Are Measured
Fitting sizes for SCH 80 PVC are based on nominal pipe size (NPS), which refers to the internal diameter of the pipe. This measurement system ensures compatibility with the corresponding SCH 80 PVC pipes. However, it’s important to note that the actual outer diameter remains the same between SCH 40 and SCH 80—only the wall thickness differs. LESSO America’s SCH 80 fittings are designed with this in mind, ensuring accurate sizing and reliable installation.
Common Sizing Options and Applications
LESSO America offers SCH 80 PVC fittings in a wide range of sizes, typically from 1/4 inch to 12 inches. Smaller sizes are often used in laboratory and light industrial systems, while larger sizes serve more robust applications such as wastewater treatment or chemical distribution. By offering precise dimensions and a consistent fit, LESSO America helps users ensure the right configuration for their systems, reducing the risk of leaks or pressure loss.
Installation Considerations
When selecting a fitting, it’s important to match the fitting size with the pipe’s nominal size, check for compatibility with system pressure ratings, and factor in temperature variations. LESSO America provides technical documentation and support to guide users in selecting the correct size for their specific needs.
Conclusion
Choosing the right size of SCH 80 PVC fittings is essential for system efficiency and safety. With LESSO America’s detailed sizing options and quality materials, users can count on proper fit and long-term performance. Whether for small-scale systems or complex industrial networks, understanding fitting sizes helps ensure each component functions as expected.
