Westlake Pipe & Fittings 1436131 1″ x 0.75″ MPT Reducing Male Adapter Hi-Max Fitting
The Westlake Pipe & Fittings 1436131 1″ × 0.75″ MPT Reducing Male Adapter Hi-Max Fitting is a heavy-duty PVC transition fitting engineered to deliver reliable performance in high-pressure plumbing, irrigation, and industrial piping systems. Designed to efficiently reduce pipe size while transitioning between solvent-weld and threaded connections, this adapter provides a secure and leak-resistant solution for professionals who demand strength, accuracy, and long-term durability.
Manufactured from premium Hi-Max PVC material, this fitting is built to outperform standard PVC adapters in demanding environments. The reinforced wall construction enhances pressure resistance and structural integrity, helping reduce the risk of cracking, deformation, or joint failure under stress. This makes the 1436131 adapter well suited for pressurized water systems, pump connections, filtration assemblies, and commercial or industrial fluid handling applications.
The 1-inch slip (socket) end is designed for solvent-weld installation using standard PVC primer and cement, creating a permanent and dependable bond with compatible PVC pipe. On the opposite end, the 0.75-inch male pipe thread (MPT) provides a versatile threaded connection to valves, manifolds, regulators, or equipment ports. This dual-connection design allows installers to seamlessly integrate rigid piping with threaded components while maintaining system integrity.
Precision manufacturing is a key advantage of this Hi-Max fitting. The male threads are cleanly molded for smooth engagement, reducing the likelihood of cross-threading and ensuring a tight seal when installed with appropriate thread sealant or PTFE tape. Consistent dimensions throughout the fitting ensure compatibility with standard piping components, improving installation efficiency and minimizing costly rework.
PVC construction offers significant advantages over traditional metal fittings. The Westlake 1436131 adapter is inherently resistant to corrosion, rust, and chemical degradation, making it ideal for both indoor and outdoor installations. Unlike metal adapters, it will not seize or deteriorate due to moisture or chemical exposure, helping extend the service life of the system while reducing maintenance requirements.
The reducing profile of this adapter helps conserve space within piping assemblies, allowing for clean, compact installations even in tight mechanical rooms or equipment enclosures. Its lightweight design makes handling and installation easier, especially during overhead or confined-space work. The neutral PVC finish blends seamlessly with existing piping systems, delivering a professional and uniform appearance.
