Maxx Supply delivers dependable, high-performance Schedule 40 PVC plugs designed to provide reliable sealing and long-lasting leak protection in demanding plumbing applications. These essential components are used to close off or cap the end of a pipe or fitting, helping maintain system integrity and preventing unwanted fluid or gas discharge.

Crafted from high-strength Schedule 40 PVC, our plugs offer outstanding durability, corrosion resistance, and pressure tolerance. Whether you're working on residential repairs, commercial builds, or industrial projects, we provide plug sizes from 3/8″ to 4″ in both spigot and threaded formats to ensure a secure fit for virtually any pipe fitting configuration.

Choosing the Right Plug

Selecting the right Schedule 40 PVC plug begins with understanding your system’s specifications. Consider the pipe material, schedule rating, pressure requirements, and thread type. Schedule 40 plugs are designed with medium wall thickness, offering strong resistance to pressure in common plumbing setups.

Both spigot and male pipe thread plug options are available for secure connections, with sizes ranging from 3/8″ to 4″. These plugs work seamlessly with other PVC fittings and white fittings for clean installations.

To ensure proper fit:

  • Measure the internal/external pipe diameter accurately.
  • Check compatibility with ASTM D2466 standards.
  • Use plugs rated for potable water applications, outdoor exposure, or drainage and irrigation systems depending on your project needs.

Schedule 40 plugs are also known for their better sound deadening qualities when compared to metal alternatives, making them ideal for noise-sensitive environments.

Plug Maintenance & Usage

Proper installation and care will extend the life of your PVC plugs.

  • Tightening: Hand-tighten followed by a quarter-turn with a wrench. Over-tightening may damage threads.
  • Reusability: If threads remain undamaged and debris-free, plugs can typically be reused.
  • Potable Safety: Most Schedule 40 plugs conform to ASTM D1784 standards for potable water, but it’s best to always confirm product labeling.
  • Temperature Range: Standard plugs perform well in temperatures between 33°F and 140°F. Avoid use in compressed air systems unless explicitly rated.

Also note: Schedule 40 is intended for pressure fittings; do not substitute for DWV or ABS foam core applications without confirming suitability.
