Westlake Pipe & Fittings 435007 0.75″ SKT x FPT Female Adapter
The Westlake Pipe & Fittings 435007 0.75″ Female Adapter is a precision-manufactured PVC plumbing fitting engineered to deliver reliable performance in a wide range of piping systems. As part of Westlake’s extensive line of Schedule 40 PVC pipe fittings, this adapter serves as a crucial transition piece that enables connection between solvent-weld (socket) connections and female pipe-threaded (FPT) connections. Westlake Pipe & Fittings is an established and trusted brand in the PVC pipe and fittings industry, known for producing quality materials used by contractors, plumbers, and engineers for commercial, residential, irrigation, and fluid handling applications.
Fundamentally, this adapter is a female adapter, meaning it has an internal thread on one end that receives a male threaded pipe or fitting, and a smooth socket on the other end that is designed to accept a piece of PVC pipe which has been cemented (solvent welded) into the socket. This combination allows for versatile installation solutions where two different joint types need to be joined seamlessly. The 0.75″ nominal size indicates the internal diameter of the fitting interfaces, making it compatible with standard 3/4″ Schedule 40 PVC pipe and threaded components.
The adapter is molded from high-quality polyvinyl chloride (PVC), a thermoplastic material widely used in piping systems for its strength-to-weight ratio, chemical resistance, and long service life. PVC is inherently corrosion-resistant, non-conductive, and less prone to deterioration than metal alternatives, particularly in environments where moisture, chemicals, or corrosive agents are present. Because of these properties, PVC pipe and fittings like this adapter are commonly specified for potable water distribution, irrigation systems, pool and spa plumbing, wastewater systems, and general fluid transport systems.

The 435007 adapter has a Schedule 40 wall thickness, which corresponds to standard pressure-rated PVC pipe specifications. While actual pressure ratings may vary with temperature and system conditions, Schedule 40 PVC fittings are typically able to handle moderate pressure applications safely when installed properly. PVC Schedule 40 pipe and fittings are rated to operate at temperatures up to approximately 140°F (60°C), beyond which material softening and deformation can occur.
One end of the adapter has a socket (SKT) connection. This socket is dimensioned to accept the outside diameter of a matching PVC pipe. Before installation, the pipe and fitting interior are coated with PVC primer and solvent cement. When these chemicals are applied correctly, the solvent weld creates a strong, permanent bond between the pipe and adapter that effectively becomes a single continuous piece. Proper solvent welding is critical for creating leak-tight systems and requires careful surface preparation and adherence to primer/cement manufacturer instructions.
On the opposite side, the fitting features female pipe threads (FPT) that conform to the National Pipe Thread (NPT) standard. These threads are tapered and engineered to form a tight, pressure-resistant seal with a corresponding male threaded (MPT) component when sealed with appropriate thread tape or joint compound. The female threads allow you to attach threaded fixtures such as valves, pumps, gauges, quick-connect fittings, or other threaded PVC or metal fittings without additional adapters or couplings.
PVC products like this adapter are typically light weight, easy to handle, and do not require heavy tools for installation. While the socket end relies on solvent welding for permanent attachment, the threaded side remains serviceable and removable, allowing for maintenance, repair, or replacement of threaded components without disturbing the bonded pipework.
