Description

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

The Westlake Pipe & Fittings 401422 4″ x 4″ x 3″ Slip x Slip x Slip Reducing Tee is a Schedule 40 PVC fitting designed to branch a 4-inch main line into a 3-inch outlet while maintaining structural strength and consistent flow performance. With two 4-inch slip sockets on the main run and a 3-inch slip socket branch, it provides an efficient solution for controlled flow distribution in plumbing, irrigation, municipal, and industrial piping systems.

Manufactured from durable PVC, the 401422 offers excellent resistance to corrosion, chemical exposure, moisture, and environmental wear. Unlike metal fittings, it will not rust, scale, or degrade over time, making it suitable for both above-ground and underground installations. Its robust construction supports long-term performance in water distribution, wastewater management, pool and spa systems, and industrial process piping.

All three slip socket connections are engineered for solvent-weld installation with standard Schedule 40 PVC pipe. When properly bonded using primer and cement, the joints form strong, leak-resistant connections that become an integral part of the piping system. This method reduces the risk of joint failure, vibration-related leaks, and ongoing maintenance concerns in continuously operating systems.

The reducing configuration provides a smooth transition from 4 inches to 3 inches, helping manage flow direction and delivery to secondary lines without excessive turbulence or pressure loss. Smooth internal surfaces promote efficient fluid movement and help protect downstream equipment from unnecessary stress.

Lightweight yet strong, the fitting is easy to handle and align during installation, reducing labor time while ensuring consistent pipe insertion depth and fit. Designed for dependable flow control and long service life, the Westlake 401422 reducing tee delivers reliable performance in demanding PVC piping applications.
