Description

Westlake Pipe & Fittings 447120 12″ Slip Cap

The Westlake Pipe & Fittings 447120 12″ Slip Cap is a heavy-duty PVC fitting designed to securely seal the end of a 12-inch Schedule 40 PVC pipe. Ideal for permanent terminations, system testing, future expansion points, or temporary closures, this slip cap provides a reliable, leak-resistant solution for large-diameter commercial, industrial, and municipal piping systems.

Constructed from high-quality Schedule 40 PVC, the 447120 cap offers excellent resistance to corrosion, chemicals, moisture, and environmental wear. Unlike metal alternatives, PVC maintains long-term structural integrity in indoor, outdoor, and underground installations when installed according to standard plumbing practices and applicable codes. Its lightweight construction simplifies handling and placement, reducing labor time and installer fatigue, even in overhead, trench, or confined-space applications.

The 12-inch slip connection fits over standard Schedule 40 PVC pipe and forms a permanent, leak-resistant joint when properly solvent-welded. Precision molding ensures consistent wall thickness and accurate dimensions, allowing for secure alignment and a proper fit with minimal effort. The smooth interior surface prevents debris accumulation and sediment buildup, supporting clean system shutdowns and facilitating future line extensions or modifications.

With a clean white exterior for professional appearance and easy visual inspection, the 447120 integrates seamlessly into new construction and retrofit projects. Its durable materials, precise manufacturing, and reliable performance make it an essential component for municipal water and wastewater systems, stormwater drainage, irrigation networks, industrial piping, and recreational or aquatic facilities.
