Description

Westlake Pipe & Fittings 437628 10″ x 8″ SP x Slip Reducer Bushing

The Westlake Pipe & Fittings 437628 10″ x 8″ SP x Slip Reducer Bushing is a heavy-duty PVC fitting designed to transition from a 10-inch pipe size to an 8-inch pipe size in large-diameter piping systems. It features a 10-inch spigot (SP) end that fits directly into the socket of a compatible 10-inch PVC fitting and an 8-inch slip socket that accepts standard Schedule 40 PVC pipe. This configuration allows for efficient downsizing while maintaining proper alignment, strength, and leak-resistant performance.

Constructed from high-quality Schedule 40 PVC, the 437628 reducer bushing provides excellent resistance to corrosion, rust, scaling, chemicals, moisture, and environmental exposure. Unlike metal fittings, PVC maintains long-term durability in demanding indoor, outdoor, and underground applications when installed according to code. Despite its large size, the fitting remains lighter than comparable metal alternatives, simplifying handling and installation.

The precision-molded interior features a smooth, contoured bore that promotes consistent flow and minimizes turbulence at the point of diameter reduction. This helps reduce pressure loss and supports efficient hydraulic performance, which is especially important in high-volume municipal, industrial, irrigation, stormwater, wastewater, and aquatic systems. When properly solvent-welded with compatible primer and cement, both connections form permanent, pressure-resistant joints designed for long-term reliability.

Fully compatible with standard Schedule 40 PVC pipe and fittings, the 437628 integrates seamlessly into new construction and retrofit projects. Its durable construction, secure connection design, and efficient flow characteristics make it an essential solution for transitioning between large pipe sizes in demanding PVC piping systems.

Westlake Pipe & Fittings has earned its reputation as one of North America’s foremost manufacturers of PVC pipe and fittings, delivering reliable infrastructure solutions for municipal, plumbing, industrial, agricultural, irrigation, water-well, electrical, and pool/spa applications. Drawing on decades of industry experience and backed by the resources of a major global materials company, the firm manages a vast manufacturing and distribution network that ensures ready availability and regional supply across the continent. Its product portfolio spans an exceptional breadth — from pressure-rated PVC conduit and solvent-weld sewer and drainage pipes to gasket sewer fittings, high-strength PVCO pressure systems, injection-molded valves, CPVC hot-water fittings, and UV-resistant electrical conduits — enabling seamless integration into virtually any water, waste, or wiring infrastructure project. By employing cutting-edge PVC technologies such as Certa-Lok® restrained joints and molecular-oriented PVCO formulations, the company advances beyond conventional piping to offer enhanced joint stability, long-term durability, and superior resistance to corrosion, chemicals, and environmental stress. Every product reflects a commitment to sustainable construction practices, lightweight and cost-effective materials, and a design life measured in decades rather than years — reducing maintenance needs, lowering lifetime infrastructure costs, and enabling project planners to build with confidence. From small residential installations to large-scale municipal or commercial works, Westlake Pipe & Fittings stands out for its engineering rigor, full-system compatibility, and capacity to meet rigorous safety and performance standards.
