Introducing
Westlake Pipe & Fittings.
A Better Foundation.

With all the talk about infrastructure and water conservation, it’s time for a better solution. An updated system—rethought using environmentally sustainable materials that are engineered to last. Reinvented using the latest technology.

A system strong enough to deliver the water we need in cities, farms and everywhere in between. But most importantly, we need it to be strong enough to last generations.

Westlake Pipe & Fittings is bringing to light the pipe and fittings that make up A Better Foundation—the foundation that connects us all.

Why PVC?

PVC pipe is among the world’s most sustainable products, ideal for long-term use in underground infrastructure. It requires less energy and fewer resources to manufacture than old-technology materials, and its production creates virtually no waste.

It’s efficient, lightweight, non-toxic, corrosion-resistant and can last for 100 years or more. Additionally, PVC derivatives like PVC-O require up to 40% less material to produce than traditional PVC, issuing a new wave of innovation across market segments.
