Description
Westlake Pipe & Fittings 447100 10″ Slip Cap
The Westlake Pipe & Fittings 447100 10″ Slip Cap is a heavy-duty PVC fitting designed to securely seal the end of a 10-inch Schedule 40 PVC pipe. Ideal for permanent terminations, system testing, future expansions, or repairs, this slip-style cap provides a reliable, leak-resistant closure for large-diameter commercial, industrial, and municipal piping systems.
Manufactured from high-quality Schedule 40 PVC, the 447100 cap offers excellent resistance to corrosion, chemicals, moisture, and environmental exposure. Unlike metal alternatives that may rust or degrade, PVC maintains structural integrity in indoor, outdoor, and underground installations when installed according to proper practices and local codes. Its lightweight construction simplifies handling and placement, reducing labor time and installer fatigue on large projects.
The 10-inch slip connection is engineered to fit over standard Schedule 40 PVC pipe and, when properly solvent-welded, forms a strong, permanent seal. Precision molding ensures consistent wall thickness and accurate dimensions, allowing for proper alignment and a secure fit without excessive adjustment. The smooth interior surface prevents debris buildup and supports clean system shutdowns, while also facilitating future modifications if the line is extended or reactivated.
The white PVC exterior provides a professional appearance and allows for easy visual inspection during installation and maintenance. Fully compatible with other Schedule 40 PVC components, the 447100 integrates seamlessly into new construction and retrofit projects. Its durable materials, precision engineering, and reliable performance make it an essential component for sealing large-diameter PVC piping in water distribution, wastewater, stormwater, irrigation, industrial, and aquatic applications.
