Description

Westlake Pipe & Fittings 437670 12″ x 10″ SP x Slip Reducer Bushing

The Westlake Pipe & Fittings 437670 12″ x 10″ SP x Slip Reducer Bushing is a heavy-duty PVC fitting designed to transition from a 12-inch pipe size to a 10-inch pipe size in large-diameter piping systems. Featuring a 12-inch spigot (SP) end and a 10-inch slip socket, it allows for smooth downsizing while maintaining structural integrity, leak resistance, and reliable system performance.

Manufactured from high-quality Schedule 40 PVC, the 437670 reducer bushing offers excellent resistance to corrosion, rust, chemicals, moisture, and environmental wear. Unlike metal fittings, PVC maintains long-term durability in indoor, outdoor, and underground installations when proper installation practices and local codes are followed. Its lightweight construction simplifies handling and alignment, reducing labor time and installer fatigue on large-scale projects.

The precision-molded interior features a smooth, tapered bore that promotes efficient fluid flow while minimizing turbulence and pressure loss at the transition point. When properly solvent-welded using compatible primer and cement, both connections form permanent, leak-resistant joints capable of withstanding demanding system conditions. This makes the fitting ideal for high-volume municipal, commercial, industrial, irrigation, stormwater, wastewater, and aquatic applications.

The clean white exterior provides a professional appearance and allows for easy visual inspection during installation and maintenance. Fully compatible with standard Schedule 40 PVC pipe and fittings, the 437670 integrates seamlessly into new construction projects and system retrofits. Its durable materials, precise dimensions, and efficient flow characteristics make it an essential component 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.
