At LESSO America, we understand how important it is to choose the right PVC plumbing fittings for your project—whether you're working on a new residential build or upgrading a commercial system. With so many fitting types, sizes, and standards available, it can be overwhelming to navigate the options. That's why we're here to help guide you through the process and ensure that the connections in your piping system are as dependable as the work you put into it.

Consider the Application: Residential vs. Commercial

One of the first things we recommend evaluating is the scale and demand of your project. For residential applications, standard SCH40 PVC fittings are usually sufficient. They handle moderate pressure and work well for cold water distribution and drainage systems around the home.

For commercial or high-pressure applications—such as irrigation systems, industrial plumbing, or multi-unit housing—we often suggest upgrading to SCH80 fittings. These fittings have thicker walls and are engineered for higher pressure performance, making them better suited to heavier loads and long-term reliability.

At LESSO America, we offer both SCH40 and SCH80 PVC fittings, each designed to meet ASTM standards, giving you peace of mind no matter your project type.

Choosing the Right Type and Size

Fittings come in a wide variety of configurations: elbows, tees, adapters, couplings, bushings, and more. We always advise starting by mapping out your system layout and identifying where each type of connection will be needed. For example:

Tees and crosses are ideal for splitting flow.

Elbows redirect flow in tight spaces.

Adapters connect pipes to threaded fixtures.

Caps and plugs seal the ends of unused pipes.

Size is equally critical. Fittings must match the pipe diameter exactly to maintain proper flow and seal. LESSO America provides fittings in a range of diameters, making it easier to find the right match without compromise.

Don't Forget About Compliance and Material Quality

All our PVC plumbing fittings are manufactured using high-quality materials that meet or exceed ASTM standards. Based in Corona, CA, we bring decades of insight from our parent company, China LESSO Group Holdings Limited, which has served global markets with reliable piping solutions. Our U.S. manufacturing and distribution operations reflect that same commitment to quality and durability.

We also offer fittings for specialized systems, including DWV (Drain, Waste, and Vent) and SDR35 sewer systems. These products are made with different structural specifications to suit their specific roles, and our team is always available to help you make the right selection.

Choosing the right PVC plumbing fittings doesn't have to be complicated. With a clear understanding of your system's needs and access to reliable, high-standard products, your project is already on the right track.
