Westlake Pipe & Fittings 439098 0.75″ x 0.25″ MPT x FPT Threaded Bushing
The Westlake Pipe & Fittings 439098 0.75″ x 0.25″ Threaded Bushing is a high-quality PVC reducing bushing designed to provide a secure and efficient transition between two different threaded pipe sizes within a piping system. Engineered for durability, precision, and long-term reliability, this threaded bushing is an essential component for plumbing professionals, irrigation installers, pool and spa technicians, and industrial system designers who require dependable size reduction without compromising system integrity.
This fitting features 3/4-inch male pipe threads (MPT) on the exterior and 1/4-inch female pipe threads (FPT) on the interior, allowing it to thread directly into a larger female-threaded fitting while accepting a smaller male-threaded component. Its compact yet robust design makes it ideal for installations where space is limited, accuracy is critical, and leak-free performance is mandatory.
Manufactured from premium-grade PVC (polyvinyl chloride), the Westlake 439098 threaded bushing offers excellent resistance to corrosion, scaling, and chemical degradation. PVC is widely used across plumbing and fluid-handling industries due to its ability to withstand moisture, pressure, and exposure to a broad range of non-aggressive chemicals without rusting or weakening over time. This makes the bushing suitable for both indoor and outdoor installations, including environments with high humidity or frequent water exposure.
The smooth internal surface of the PVC helps maintain efficient flow characteristics while reducing the risk of buildup or restriction at the transition point. The material’s lightweight nature also simplifies handling and installation, reducing strain during assembly while maintaining the strength needed for pressure-rated systems.
Both the male and female threads on this reducing bushing are precision-formed to standard NPT (National Pipe Thread) specifications. This ensures compatibility with a wide range of commonly used threaded PVC fittings, valves, gauges, pumps, and adapters. When installed correctly using appropriate thread sealant or PTFE tape, the bushing creates a tight, leak-resistant seal that holds up under normal operating pressures.
The 3/4-inch MPT outer threads allow the bushing to be easily threaded into a larger fitting, such as a coupling, tee, valve body, or manifold port. The 1/4-inch FPT internal threads then accept smaller threaded components, making this fitting particularly useful for adapting instruments, control lines, or auxiliary connections within a larger piping network.
Reducing bushings play a critical role in modern piping systems by allowing designers and installers to integrate components of varying sizes without redesigning the entire system. The Westlake 439098 threaded bushing offers a clean and efficient solution for downsizing threaded connections while maintaining structural strength and pressure performance.
This size reduction is commonly required when connecting pressure gauges, flow sensors, air release valves, chemical injection lines, or control fittings to larger supply lines. By using a single compact bushing, installers can reduce the number of joints required, minimizing potential leak points and simplifying system layout.
Designed for use with Schedule 40 PVC systems, this threaded bushing provides a dependable balance of strength and ease of installation. Schedule 40 fittings are widely accepted across industries for pressure and non-pressure applications, making this bushing a versatile component that integrates smoothly with existing infrastructure.
The compact form factor does not sacrifice performance, allowing it to maintain reliable operation over long service periods with minimal maintenance requirements. Proper installation ensures consistent sealing and structural stability, even in systems that experience frequent on-off cycling or moderate pressure fluctuations.
