Description

Westlake Pipe & Fittings 435-015 Female Adapter, 1.5″ Socket x FPT

The Westlake Pipe & Fittings 435-015 Female Adapter is a premium-grade PVC fitting engineered to connect a 1.5-inch PVC pipe to a corresponding male-threaded component, providing a secure, leak-resistant transition between solvent-welded and threaded systems. With one end designed as a smooth socket (slip) connection and the other end featuring precision-machined female pipe threads (FPT), this adapter offers an efficient and durable connection point in a wide range of plumbing, irrigation, and industrial applications. Manufactured from high-quality polyvinyl chloride (PVC) material, the 435-015 is built to deliver long-lasting performance in both pressurized and non-pressurized systems.

Engineered for reliability, the adapter’s socket end is dimensionally consistent for easy solvent welding with standard PVC piping. When used with appropriate primer and solvent cement, it creates a permanent, watertight bond capable of withstanding high internal pressures without leaks or joint failures. The female threaded end provides a versatile interface for connecting to metal or plastic male-threaded components such as valves, pumps, filters, or transition fittings. Its threads are formed to exacting standards, ensuring a smooth fit and consistent torque without cross-threading or binding.

Durability and chemical resistance are core features of the Westlake 435-015. The PVC material is non-corrosive, immune to rust, and resistant to most common chemicals, acids, alkalis, and salts, making it ideal for environments where metallic fittings would degrade over time. It is also lightweight yet strong, making handling and installation simple while maintaining the mechanical integrity needed for heavy-duty applications. The fitting’s robust construction ensures dimensional stability under temperature variations and pressure cycles, which contributes to its long service life.

The 435-015 Female Adapter is used across multiple industries due to its versatility. In residential and commercial plumbing, it serves as a connector between threaded fixtures and smooth PVC lines for cold water distribution or waste systems. In irrigation networks, it facilitates easy connection between piping and sprinkler heads, valves, or control assemblies. In industrial and chemical systems, it enables quick transitions between rigid PVC piping and equipment requiring threaded interfaces, allowing for maintenance or replacement without cutting pipe sections.

Additionally, the 435-015 maintains compliance with relevant industry standards for PVC fittings, ensuring it meets performance expectations for pressure ratings, tensile strength, and chemical compatibility. Whether used in water treatment facilities, agricultural irrigation, swimming pools, or general plumbing applications, the Westlake Pipe & Fittings 435-015 Female Adapter offers unmatched reliability, simplicity, and longevity.
