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.
Specifications
A specialized high-flow plumbing fitting designed to connect 2-inch PVC pipes at a gradual 90-degree angle. The extended radius "sweep" design significantly reduces water turbulence and friction loss, improving the overall hydraulic efficiency of filtration systems.
Sweep 90� Elbow: ~5.7 ft of straight pipe.
Cumulative Effect: Using 10 sweeps saves ~30 ft of head.

?? Critical Plumbing Warnings
- 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).
