Description

Westlake Pipe & Fittings 401422 4″ x 4″ x 3″ SKT Reducing Tee

The Westlake Pipe & Fittings 401422 Reducing Tee is a durable, professional‑grade plumbing component designed to offer a secure, efficient three‑way connection with built‑in size reduction from 4‑inch main lines to a 3‑inch branch line. Precision‑manufactured from premium Schedule 40 PVC, this reducing tee is ideal for a wide range of applications including pool and spa systems, residential and commercial irrigation networks, ponds and fountains, landscape water features, and general water distribution systems. Its robust construction, smooth fluid passage, and reliable joint integrity help ensure long‑lasting performance and leak‑resistant operation.

At the core of the 401422’s superior performance is its high‑quality PVC composition, which delivers excellent resistance to corrosion, chemical exposure, and UV degradation. Where metal fittings may rust, scale, or fail over time, PVC maintains strength, rigidity, and dimensional stability — even in environments with chlorinated water, fertilizers, or other chemical treatments.

The socket (SKT) connections on all three ends are designed for use with standard Schedule 40 PVC pipe, which is widely available and easy to install. When joined using solvent‑weld techniques with PVC primer and cement, each connection forms a permanent, watertight seal that integrates seamlessly with the piping system. This solvent‑weld bond not only prevents leaks but also helps create a unified piping network that withstands pressure cycles and long‑term use without degradation.

One of the key advantages of the 401422 Reducing Tee is its ability to combine flow distribution and size transition within a single fitting. The two 4‑inch socket ends serve as the main line, handling primary fluid flow, while the 3‑inch branch outlet allows for an efficient transition to a secondary line or auxiliary connection. This eliminates the need for separate reducers or additional fittings, simplifying system design, reducing material costs, and minimizing potential leak points. Whether you’re routing water to a secondary irrigation zone, supplying a smaller sub‑circuit, or adding a branch to accommodate equipment like filters or pressure gauges, this reducing tee delivers professional‑grade versatility.

Internally, the fitting’s smooth bore ensures consistent fluid dynamics. The transition from the larger mainline to the smaller branch is engineered to minimize turbulence and pressure loss, which helps maintain efficient flow throughout the system.

Installation of the 401422 Reducing Tee is straightforward and installer‑friendly. The lightweight PVC structure allows for easy handling and alignment, even in confined or elevated spaces. Its precision‑molded design also ensures compatibility with other Schedule 40 PVC components, making it easy to integrate into both new constructions and retrofit projects.
