At 247Garden, we understand the importance of having reliable and versatile fittings for various applications. Our PVC fittings, available in both Schedule-40 and Schedule-80, are designed to meet the demands of a wide range of industries. In this blog, we’ll delve into the different sizes of our PVC fittings and their ideal use cases, ensuring you select the perfect fit for your specific needs.

Schedule-40 vs. Schedule-80 PVC Fittings

Before we explore the different sizes, it's essential to understand the difference between Schedule-40 and Schedule-80 PVC fittings.

  • Schedule-40 PVC fittings are commonly used in applications that do not require high-pressure resistance. They are ideal for residential and light commercial plumbing, irrigation systems, and other low-stress applications.
  • Schedule-80 PVC fittings are thicker and have a higher pressure rating, making them suitable for industrial and high-pressure applications. They are used in chemical processing, water treatment, and other demanding environments.

PVC Standards and Certifications

When selecting PVC fittings, it's crucial to consider the standards and certifications that ensure the product's quality, safety, and suitability for specific applications. Our PVC fittings adhere to several key standards and certifications:

  • NSF Certification: The NSF (National Sanitation Foundation) certification ensures that PVC fittings are safe for use with potable water. Products with this certification have been tested for contaminants and are guaranteed to meet health and safety standards.
  • ASTM Standards: The American Society for Testing and Materials (ASTM) sets international standards for materials, products, systems, and services. Our PVC fittings comply with relevant ASTM standards, such as ASTM D1784 for PVC compounds and ASTM D2466 for Schedule-40 fittings. Compliance with these standards ensures consistency in material quality and performance.
  • ANSI Standards: The American National Standards Institute (ANSI) oversees the development of consensus standards for products and systems. PVC fittings that meet ANSI standards have been evaluated for safety, reliability, and functionality.
  • Safe for Potable Water: Many of our PVC fittings are certified safe for use with potable water, making them suitable for residential and commercial plumbing systems. This certification guarantees that the fittings do not leach harmful chemicals into the water supply.
