Description

Westlake Pipe & Fittings 438338 3″ x 2″ Spigot x FPT Reducing Bushing

The Westlake Pipe & Fittings 438338 3″ x 2″ Reducing Bushing is a high-quality PVC fitting engineered to provide a reliable and efficient size reduction within piping systems that require a transition from a larger hub or socket opening to a smaller female threaded connection. Designed for durability, dimensional accuracy, and long-term performance, this reducing bushing is an essential component for plumbing, irrigation, pool and spa, and light industrial piping applications where adaptability and leak-resistant connections are critical.

This fitting features a 3-inch spigot (SPG) end that is designed to solvent-weld into a 3-inch socket or hub, and a 2-inch female pipe thread (FPT) outlet that accepts standard male threaded components. By combining a solvent-weld connection with a threaded outlet, the 438338 bushing allows installers to integrate threaded valves, adapters, gauges, or equipment into larger PVC piping systems without excessive fittings or complex modifications.

Manufactured from rigid PVC (polyvinyl chloride), the Westlake 438338 reducing bushing offers excellent resistance to corrosion, scaling, and chemical attack. PVC is widely used in fluid-handling systems because it does not rust, pit, or degrade when exposed to water, moisture, or many common chemicals. This makes the fitting suitable for both indoor and outdoor installations, including buried piping where long service life is required.

The primary function of the 438338 reducing bushing is to reduce a 3-inch piping connection down to a 2-inch threaded outlet in a compact and efficient manner. Instead of using multiple fittings—such as reducers combined with adapters—this single bushing simplifies system design, saves installation time, and reduces potential leak points.

The spigot x FPT configuration provides flexibility in system layout. The spigot end solvent-welds directly into a socket, forming a permanent, pressure-capable joint. The FPT side allows for threaded connections that can be removed or replaced as needed, which is particularly beneficial for valves, sensors, or components that may require future maintenance or upgrades.

The internal geometry of the reducing bushing promotes a smooth transition between pipe sizes, helping maintain efficient flow and reducing turbulence within the system. This is especially important in applications where consistent flow, pressure stability, or equipment protection is required.

This reducing bushing is designed for use with Schedule 40 PVC piping systems, which are commonly used for pressure and non-pressure applications. Schedule 40 provides a balance of wall thickness and strength, making it suitable for residential, commercial, and light industrial systems.

When installed correctly using approved solvent cement and thread sealants, the 438338 bushing provides a strong, leak-resistant connection capable of handling typical system pressures associated with Schedule 40 PVC. Its robust construction ensures that it maintains its shape and sealing performance over time, even in environments subject to temperature fluctuations or regular water flow.

Ease of installation is a key advantage of the Westlake 438338. The spigot end inserts smoothly into a compatible socket or hub, allowing for even cement distribution and strong solvent bonding. The female threaded outlet is clearly defined, making it easy to align and tighten male threaded components without cross-threading.

Because this bushing combines size reduction and threading in one fitting, it reduces the number of joints required in the piping assembly. Fewer joints not only speed up installation but also improve system reliability by minimizing potential failure points.
