Types of 1-1/4 Inch PVC Fittings
Couplings
Couplings are straightforward fittings used to connect two lengths of PVC pipe. They are essential in applications where a continuous length is needed, such as in drain, waste, and vent systems. Available at retailers like Lowe’s and Formufit, couplings come in various grades, including standard and furniture-grade options.
Tees
Tees are designed to connect three pipes, allowing for a branch line to be created from a main line. This is particularly useful in plumbing applications where multiple outlets are required from a single source. Formufit offers a selection of furniture-grade tees that are ideal for structural applications.
Elbows
Elbows are crucial for redirecting the flow of liquids or gases. They come in different angles, with 90° and 45° being the most common. These fittings are widely used in both residential and commercial plumbing systems. You can find high-quality elbows at 247Garden and US Plastic.
Caps
Caps are used to seal the end of a pipe, preventing the escape of fluids or gases. They are beneficial in both plumbing and structural applications when a line needs to be terminated. Various styles can be found at Plumbing Supply and PVC Fittings Online.
Crosses
Cross fittings are less common but are useful when connecting four pipes at a single junction. They are typically used in complex plumbing systems where multiple branches are required. Many retailers, including Ace Hardware, stock these fittings for specialized applications.
Flanges
Flanges provide a robust connection between pipes, particularly in heavy-duty applications. They feature a flat surface for bolting and are essential in industrial settings. Flanges can be sourced from suppliers like VOSS.
