Description

Westlake Pipe & Fittings 401-420 Reducing Tee, 4″ Slip x 4″ Slip x 2″ Slip

The Westlake Pipe & Fittings 401‑420 Reducing Tee is a premium Schedule 40 PVC fitting built to deliver reliable performance, structural integrity, and leak‑resistant connections in large‑scale fluid systems. Designed with two 4‑inch slip connections and a 2‑inch slip branch, this reducing tee allows installers to efficiently split or redirect flow from a main 4‑inch pipeline into a smaller 2‑inch branch line without sacrificing strength or versatility. Whether you are installing residential plumbing, commercial water distribution, agricultural irrigation, pool/spa systems, or industrial fluid networks, this fitting offers a professional‑grade solution that enhances system flexibility and performance.

Constructed from high‑quality Schedule 40 PVC, the 401‑420 Reducing Tee provides superior resistance to corrosion, chemical exposure, and environmental deterioration. PVC inherently resists rust, pitting, and mineral buildup — common issues with metal fittings — ensuring long‑lasting performance even in harsh environments with frequent water contact, chemical fertilizers, or chlorinated solutions. This durability makes the tee suitable for both indoor and outdoor use, maintaining its integrity under pressure and changing weather conditions.

The dual 4‑inch slip ends are engineered for solvent‑weld attachment to standard 4‑inch PVC pipe using industry‑standard PVC primer and cement. These solvent‑weld joints create permanent, watertight connections that stand up to daily wear and pressure fluctuations. The 2‑inch slip branch enables a seamless transition to a smaller pipe size, allowing easy integration of branch lines for irrigation zones, filtration equipment, valves, or auxiliary systems.

One of the key advantages of the Westlake 401‑420 Reducing Tee is its ability to maintain efficient fluid transfer dynamics even while reducing pipe size. The smooth interior walls of the fitting help minimize turbulence and pressure loss across the transition, which supports steady flow and reduces strain on pumps and other system components.

Installation is straightforward and efficient. The solvent‑weld slip connections require only standard PVC tools and materials — primer, cement, and proper pipe cutting — making the part suitable for professional contractors and experienced DIY installers alike. The lightweight PVC design simplifies handling, especially in overhead or hard‑to‑reach applications, while maintaining the structural integrity needed for pressurized systems.

The Westlake 401‑420 Reducing Tee is engineered to meet ASTM Schedule 40 specifications, ensuring precise dimensions, reliable performance, and compatibility with a wide range of Schedule 40 PVC components. Its dependable construction minimizes the risk of leaks, misalignment, or premature failure, providing peace of mind for long‑term installations.
