Description

Westlake Pipe & Fittings 409040SW 90-Degree Sweep Elbow, 4″ SL x SP

The Westlake Pipe & Fittings 409040SW 4″ 90-Degree Sweep Elbow, SL x SP is a professional-grade PVC fitting designed to provide a smooth, gradual directional change in medium-diameter piping systems. Its sweep design reduces turbulence and maintains optimal flow efficiency, making it ideal for residential, commercial, and industrial applications such as plumbing, irrigation, pool and spa systems, and water treatment facilities.

Constructed from high-quality PVC, the 409040SW offers excellent corrosion resistance, chemical stability, and structural integrity. Unlike metal fittings, it will not rust, pit, or degrade over time. The smooth internal surface minimizes friction and pressure loss, ensuring consistent flow while reducing wear on pumps, valves, and other system components. This makes it a low-maintenance, long-lasting solution for professionals requiring reliable performance.

The gradual curve of the sweep elbow provides a more efficient directional transition than a standard 90-degree bend, reducing velocity changes, turbulence, and system noise. The precision-molded slip and spigot ends create a secure, leak-resistant connection compatible with standard Schedule 40 PVC piping, allowing seamless integration into new or existing systems.

Lightweight and easy to handle, the 409040SW simplifies installation, alignment, and positioning. Its versatility supports a wide range of applications, including residential water systems, irrigation networks, pool and spa circulation, municipal water distribution, wastewater management, and industrial fluid systems. The smooth interior also prevents sediment buildup, reducing maintenance and minimizing the risk of clogs.

In summary, the Westlake 409040SW 4″ 90-Degree Sweep Elbow provides a durable, high-performance solution for smooth flow transitions in PVC piping systems. Its premium material construction, efficient sweep design, and compatibility with standard piping make it a trusted choice for contractors, engineers, and DIY installers, delivering reliable, long-term performance across a variety of residential, commercial, and industrial projects.
