Westlake Pipe & Fittings 439072 0.5″ x 0.25″ MPT x FPT Threaded Bushing

The Westlake Pipe & Fittings 439072 0.5″ x 0.25″ Threaded Bushing is a precision-molded PVC fitting designed to provide a dependable and efficient solution for reducing threaded pipe connections within a wide range of plumbing and fluid-handling systems. Manufactured to exacting standards, this threaded bushing enables installers to seamlessly transition from a larger threaded opening to a smaller threaded connection while maintaining strength, alignment, and leak resistance.

Threaded bushings play a critical role in piping systems where flexibility, adaptability, and system expansion are required. The Westlake 439072 bushing features a 0.5-inch male pipe thread (MPT) exterior and a 0.25-inch female pipe thread (FPT) interior, allowing it to be installed directly into a larger female threaded fitting while accepting a smaller male-threaded component. This configuration is especially useful when connecting valves, gauges, emitters, sensors, or specialty equipment that require smaller thread sizes without reworking or replacing existing piping infrastructure.

This threaded bushing is manufactured from high-quality PVC (polyvinyl chloride), a material widely recognized across plumbing, irrigation, industrial, and pool & spa applications for its excellent balance of strength, chemical resistance, and long-term durability. PVC is naturally resistant to corrosion, rust, scaling, and most common chemicals found in water distribution systems. Unlike metal fittings, it will not pit, seize, or degrade when exposed to moisture, making it ideal for both indoor and outdoor installations.

The smooth molded finish of the bushing enhances thread engagement and helps ensure a tight, uniform seal when used with standard thread sealants such as PTFE tape or pipe dope. This results in improved leak prevention and consistent performance over the lifespan of the system.

The male pipe thread (MPT) on the exterior of the bushing is formed to industry-standard NPT (National Pipe Thread) specifications, ensuring compatibility with commonly used female threaded PVC fittings, manifolds, valves, and adapters. The female pipe thread (FPT) on the interior is equally precise, allowing smaller male-threaded components to thread in smoothly and securely.

Accurate threading is essential in pressure and flow systems, and Westlake’s manufacturing process emphasizes dimensional accuracy and thread consistency. This helps reduce the risk of cross-threading, uneven sealing, or stress fractures during installation.

The compact design of the 439072 threaded bushing allows it to be used in tight spaces where larger reducing fittings would be impractical. Despite its small size, the bushing provides a robust transition point that maintains structural integrity and alignment within the piping assembly. Its low-profile shape minimizes protrusion, helping maintain a clean and organized piping layout.

This design also makes the bushing well-suited for retrofits and repairs, where space constraints or existing piping configurations limit the use of bulkier fittings.

Installation of the Westlake 439072 is straightforward and efficient. The male threaded end is inserted into a compatible female fitting, while the smaller male-threaded component is threaded into the bushing’s female interior. When installed using appropriate thread sealant, the bushing forms a secure, leak-resistant joint capable of handling typical operating pressures associated with Schedule 40 PVC systems.

PVC’s lightweight nature makes handling easy, reduces installer fatigue, and speeds up job completion. The bushing’s clean white finish also allows for quick visual inspection during installation and maintenance.
