Description
Westlake Pipe & Fittings 402420 4″ x 4″ x 2″ SKT x SKT x FPT Reducing Tee
The Westlake Pipe & Fittings 402420 Reducing Tee is a heavy-duty PVC plumbing fitting engineered to create a reliable three-way connection in 4-inch piping systems while reducing one outlet to 2 inches. Designed with two 4-inch socket (SKT) connections and one 2-inch female pipe thread (FPT) outlet, this reducing tee allows installers to integrate smaller threaded components into large-diameter PVC pipelines with ease. Its robust construction and versatile design make it ideal for commercial and residential pool plumbing, irrigation systems, water features, industrial water handling, and large-scale fluid distribution applications.
Manufactured from high-quality Schedule 40 PVC, the 402420 Reducing Tee delivers excellent resistance to corrosion, chemical exposure, and environmental stress. Unlike metal fittings that can rust or scale over time, PVC maintains its structural integrity when exposed to moisture, chlorinated water, fertilizers, and UV light. This durability ensures long-term performance in both indoor and outdoor installations, even in demanding environments where reliability is critical.
The 4-inch socket ends are designed for solvent-weld installation using standard PVC primer and cement. When properly installed, the pipe and fitting form a permanent, watertight bond that becomes an integral part of the system. The 2-inch FPT outlet provides a convenient threaded connection point for valves, adapters, gauges, chemical feeders, or auxiliary branch lines. When paired with PTFE tape or an approved thread sealant, the threaded outlet creates a secure, leak-resistant joint without the need for additional adapters.
One of the key benefits of the 402420 Reducing Tee is its ability to combine large-diameter slip connections with a reduced threaded outlet in a single fitting. This integrated design simplifies plumbing layouts, reduces material costs, and minimizes the number of joints—helping to lower the risk of leaks. It is particularly useful on pool equipment pads, irrigation manifolds, pump discharge lines, and filtration systems where a smaller threaded connection must be introduced into a high-flow pipeline.
Internally, the fitting features a smooth, contoured flow path that minimizes turbulence and pressure loss. This helps maintain efficient system performance, even in high-volume applications where consistent water flow is essential. The lightweight nature of PVC compared to metal alternatives also makes handling and installation easier, especially when working with large-diameter pipe in confined or elevated spaces.
In summary, the Westlake Pipe & Fittings 402420 4″ x 4″ x 2″ SKT x SKT x FPT Reducing Tee offers professional-grade strength, durability, and versatility for demanding plumbing applications. With its corrosion-resistant PVC construction, secure solvent-weld sockets, and reduced threaded outlet, this fitting provides a dependable solution for integrating smaller threaded components into large PVC piping systems.
