Description

Westlake Pipe & Fittings 429080 8″ Slip x Slip Coupling

The Westlake Pipe & Fittings 429080 8″ Slip x Slip Coupling is a heavy-duty Schedule 40 PVC fitting designed to securely join two sections of 8-inch pipe in large-diameter piping systems. It provides a straight, seamless connection that maintains pipeline integrity while supporting consistent fluid flow. Suitable for municipal water systems, irrigation networks, pool plumbing, wastewater lines, and industrial applications, this coupling delivers reliable performance in both new installations and system repairs.

Constructed from high-quality PVC, the 429080 coupling offers excellent resistance to corrosion, rust, chemical exposure, and environmental wear. Unlike metal alternatives, it will not pit or degrade over time, ensuring long-term durability in demanding conditions. Its smooth interior surface reduces friction and turbulence, helping maintain steady flow rates while minimizing stress on pumps, valves, and filtration equipment.

The 8-inch slip x slip configuration allows for straightforward solvent-weld installation with standard 8-inch Schedule 40 PVC pipe. Precision-molded hubs ensure proper alignment and a tight, leak-resistant bond when installed with PVC cement. Despite its large size, the lightweight PVC construction makes handling and positioning easier, reducing installation time and labor effort on the job site.

Engineered to withstand standard operating pressures, the coupling provides a stable connection that resists minor stresses from vibration and temperature fluctuations. Its smooth, uninterrupted bore helps prevent sediment buildup and pressure loss, contributing to efficient, low-maintenance system performance in both pressurized and gravity-flow applications.

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.
