Product Description

The 2" Schedule 40 PVC 90° Sweep Elbow (406-020S) is a specialized plumbing fitting used to connect two sections of 2-inch PVC pipe at a gradual 90-degree angle. Unlike standard "short-radius" elbows, the "sweep" design features an extended radius curve that significantly reduces water turbulence and friction loss, improving the overall hydraulic efficiency of a filtration system.

Key Product Features

  • Optimal Flow Dynamics: The long-radius sweep minimizes "feet of head" (resistance), allowing water to transition direction smoothly with up to 50% less turbulence than standard elbows.
  • Dual Socket Connections: Features two "hub" or "slip" ends designed for solvent welding (gluing) over 2-inch Schedule 40 pipe.
  • Corrosion Resistant: Constructed from high-quality PVC that is immune to scaling, rot, and electrochemical corrosion, making it ideal for chlorinated pool water and chemical processing.

High-Pressure Reliability: Engineered for pressure applications with a maximum operating pressure typically rated at 166 PSI at 73°F.

⚠️ Critical Plumbing Warnings

NO COMPRESSED AIR: Never use PVC pipe or fittings for compressed air or gases. PVC can shatter violently under gas pressure, causing fatal injury or property damage.
TEMPERATURE LIMIT: Do not use in applications exceeding 140°F. High temperatures (hot water/steam) will soften the PVC, leading to structural failure and leaks.
CHEMICAL COMPATIBILITY: Avoid contact with ketones (acetone), aromatic solvents, or chlorinated hydrocarbons, as these will melt or degrade the chemical bonds of the PVC.
💡 Professional Installation Tips
  • Solvent Welding: Use high-quality PVC primer and cement. Apply to both pipe and elbow, insert with a quarter-turn, and hold for 30 seconds to prevent "push-out."
  • Space Management: Sweep elbows occupy more room than standard 90s. Plan your equipment pad layout accordingly.
  • TDH Calculation: To find your total resistance, add the actual pipe length to the "equivalent lengths" of all fittings (5.7 ft per sweep).
PROCEED WITH CAUTION: High-pressure plumbing involves risk. Professional installation by a licensed pool technician is recommended to ensure leak-free solvent welds and proper hydraulic design.
