Westlake Pipe & Fittings 439210 1.5″ x 0.75″ MPT x FPT Threaded Bushing

The Westlake Pipe & Fittings 439210 1.5″ x 0.75″ Threaded Bushing is a high-quality PVC fitting engineered to provide a dependable size-reduction solution in threaded piping systems. Designed for durability, dimensional accuracy, and long-term performance, this threaded bushing allows installers to efficiently transition from a 1.5-inch male pipe thread (MPT) connection down to a 0.75-inch female pipe thread (FPT) connection. It is an essential component for plumbing professionals, contractors, and system designers who require a clean, secure, and leak-resistant method of adapting pipe sizes without reconfiguring entire piping runs.

Manufactured by Westlake Pipe & Fittings, a recognized leader in thermoplastic piping solutions, this threaded bushing reflects the brand’s commitment to consistent quality and reliable performance. It is specifically designed to meet the needs of residential, commercial, industrial, and irrigation applications where threaded PVC connections are preferred for ease of installation, adjustability, and maintenance accessibility.

The primary function of the 439210 threaded bushing is to reduce pipe size while maintaining full threaded compatibility on both ends. The 1.5″ MPT exterior threads are designed to thread directly into a corresponding 1.5″ female threaded fitting, valve, or pipe opening. Once installed, the internal 0.75″ FPT threads allow a smaller threaded pipe or component to be connected securely. This design eliminates the need for multiple fittings or complex transitions, helping streamline installations and reduce potential leak points.

Threaded bushings are especially valuable in systems that may require future disassembly, upgrades, or component replacement. Unlike solvent-weld fittings, threaded connections can be removed with minimal disruption, making this bushing an excellent choice for serviceable plumbing assemblies, pump connections, and mechanical equipment interfaces.

The Westlake 439210 bushing is manufactured from high-quality PVC (polyvinyl chloride), a material widely used in fluid handling systems due to its exceptional resistance to corrosion, scaling, and chemical attack. PVC does not rust, pit, or degrade when exposed to moisture, making it ideal for both indoor and outdoor installations.

The rigid PVC construction offers an optimal balance of strength and lightweight handling. This ensures the bushing can withstand typical operating pressures associated with Schedule 40 piping systems while remaining easy to transport, handle, and install. The smooth molded surface also contributes to clean thread engagement and reliable sealing when used with appropriate thread sealants such as PTFE tape or compatible pipe dope.

Both the male and female threads on this bushing are molded to industry-standard pipe thread tolerances. The male pipe threads provide a firm, consistent engagement with mating fittings, while the female pipe threads accept standard 0.75″ threaded pipe or components without cross-threading or excessive resistance. This precision helps ensure a tight, leak-resistant seal when properly installed.

The bushing’s long-body profile provides additional thread engagement compared to shorter fittings, enhancing mechanical strength and sealing reliability. This is particularly beneficial in applications subject to vibration, pressure fluctuations, or frequent maintenance.

One of the key advantages of this threaded bushing is installation efficiency. By reducing pipe size within a single fitting, it minimizes the number of components required, saving time, labor, and material costs. Threaded connections allow for precise alignment and easy adjustment during assembly, which is especially helpful in tight or complex piping layouts.

When installed correctly using proper thread sealing methods, the bushing provides a dependable connection that maintains system integrity over time. Its durable construction supports long service life, even in demanding environments.
