Description

Westlake Pipe & Fittings 437337 3″ x 1.5″ Spigot x SKT Reducing Bushing

The Westlake Pipe & Fittings 437337 3″ x 1.5″ Reducing Bushing is a high-quality PVC fitting designed to provide a smooth, dependable transition between different pipe sizes within a piping system. Engineered for durability, precision, and ease of installation, this reducing bushing is ideal for a wide range of plumbing, irrigation, pool & spa, and general fluid-handling applications. As part of the trusted Westlake Pipe & Fittings lineup, it reflects consistent manufacturing standards and long-term performance reliability.

This reducing bushing features a 3-inch spigot end that fits inside a 3-inch socket fitting, and a 1.5-inch socket (SKT) outlet that accepts standard 1.5-inch PVC pipe. This configuration allows installers to efficiently reduce line size without adding unnecessary fittings, helping streamline system layouts and minimize potential leak points. It is particularly useful in applications where larger main lines must be stepped down to feed smaller branch lines or equipment connections.

Manufactured from high-grade PVC (polyvinyl chloride), the Westlake 437337 reducing bushing offers excellent resistance to corrosion, rust, scaling, and chemical degradation. Unlike metal fittings, PVC does not react with water or most common chemicals, making it a dependable choice for long-term use in both indoor and outdoor installations. Its non-conductive and non-toxic properties also make it suitable for potable water systems when used in accordance with applicable plumbing codes.

The fitting is produced to Schedule 40 standards, ensuring compatibility with commonly used Schedule 40 PVC pipe and fittings. Schedule 40 PVC is widely selected for pressure and non-pressure applications due to its balance of strength, wall thickness, and ease of handling. This makes the reducing bushing suitable for systems operating under typical working pressures found in residential, commercial, and light industrial environments.

One of the key advantages of the Westlake 437337 reducing bushing is its compact, efficient design. By combining reduction and connection into a single component, it reduces the need for additional couplings or adapters. This not only simplifies installation but also improves overall system integrity by minimizing the number of joints where leaks could potentially occur.

The spigot end is designed to solvent-weld directly into the socket of a larger fitting, creating a strong, permanent bond when used with appropriate PVC primer and cement. The socket end allows standard PVC pipe to be solvent-welded in place, ensuring a leak-resistant and durable connection. When installed correctly, these solvent-weld joints form a chemically fused bond that is often stronger than the pipe itself.

The internal geometry of the bushing supports a smooth flow transition from the larger diameter to the smaller one. This helps reduce turbulence and pressure loss, which is particularly beneficial in systems where consistent flow is important, such as pool circulation systems, irrigation networks, and water distribution lines.

The Westlake 437337 reducing bushing is lightweight and easy to handle, making it installer-friendly even in tight or overhead spaces. Its clean, uniform dimensions ensure predictable fitment, which saves time during layout and assembly. The white PVC finish also makes it easy to visually inspect solvent-weld joints during and after installation.

Because the fitting follows industry-standard sizing conventions, it integrates seamlessly with existing PVC piping systems. Whether used in new construction, system upgrades, or repair work, installers can rely on consistent sizing and compatibility without the need for special tools or custom modifications.
