At LESSO America, we know how important it is for engineers and professionals in North America to choose the right components when designing or maintaining a piping system. Whether you're planning a large-scale installation or replacing a single section, knowing the function of each type of PVC pipe and fittings can help you avoid delays and ensure long-term reliability. In this guide, we break down the most commonly used fittings—what they do and where they fit best.

Elbows: Changing Direction with Control

PVC elbows are essential when your pipe system needs to turn a corner. We offer both 90-degree and 45-degree elbow options that allow you to redirect flow smoothly. The 90-degree elbow is more common in tight layouts, while the 45-degree elbow offers a gentler transition, reducing pressure loss in higher-flow systems.

In pressure or drainage applications, these fittings must match the pipe's diameter and pressure class to prevent leaks or failure. That's why we manufacture our elbows to consistent tolerances and provide detailed spec sheets for engineers who need exact compatibility.

Tees: Branching Made Simple

Tees allow fluid to branch off in a different direction. We offer standard and reducing tees in various configurations, helping you integrate additional lines with ease. Standard tees are ideal when all three branches are the same size, while reducing tees connect different diameters within the same system.

For commercial and industrial installations, tees must be chosen carefully to maintain balanced flow. Our product line includes options for both pressure and drainage systems, making them suitable for a wide range of applications.

Couplings: Connecting Sections Securely

Couplings are straightforward yet essential. They connect two straight sections of pipe and are especially useful when repairing or extending a system. We supply both standard and slip couplings, as well as repair couplings that slide over existing pipes for easier maintenance.

These fittings may seem simple, but choosing the wrong one can create weak points in the system. We make sure our couplings match our pipes exactly, so fit and seal integrity are never in question.

Other Common Fittings: Caps, Adapters, and Bushings

Besides elbows, tees, and couplings, we offer a range of additional fittings to complete your system. Caps are used to seal the end of a pipe temporarily or permanently. Adapters help transition between PVC and metal piping systems. Bushings are designed to reduce pipe size in tight spaces where a full tee or coupling isn't feasible.

Each of these parts plays a unique role, and we work hard to ensure they're manufactured to the same standards as our core fittings. That means consistent dimensions, smooth finishes, and reliable performance.

Conclusion

We've designed our full line of PVC pipe and fittings to support both experienced professionals and those new to system design. At LESSO America, our goal is to make it easier for you to identify and choose the right components, with quality you can count on. Let us know how we can support your next project—from the first elbow to the final cap.
