Westlake Pipe & Fittings 447-040 Slip Cap, 4″ Slip
The Westlake Pipe & Fittings 447-040 Slip Cap, 4″ Slip, is a premium PVC fitting designed to securely close the end of a 4-inch Schedule 40 PVC pipe. Engineered for durability, reliability, and long-lasting performance, this slip cap is ideal for a wide range of applications, including pool and spa plumbing, irrigation systems, residential and commercial water lines, and industrial fluid transport. It provides a dependable, leak-resistant seal that protects open pipe ends from debris, contamination, or unwanted water flow.
Constructed from high-quality Schedule 40 PVC, the 447-040 Slip Cap offers excellent resistance to corrosion, chemical exposure, and UV degradation. Unlike metal caps, PVC does not rust, scale, or deteriorate over time, making it suitable for both indoor and outdoor installations. Its robust construction allows it to withstand high-pressure water flow, temperature fluctuations, and continuous use, ensuring reliable performance in professional, residential, and industrial applications. Contractors, irrigation specialists, pool professionals, and industrial technicians trust Westlake fittings for their precision and durability.
The 4-inch slip connection allows for quick and easy installation using standard PVC primer and solvent cement. This ensures a strong, watertight bond between the cap and the pipe, preventing leaks and maintaining system integrity. The smooth interior preserves consistent flow when installed temporarily or permanently on pipelines, helping to minimize turbulence and protect upstream components from pressure changes. Its lightweight construction makes handling and placement simple, even in tight or confined spaces, without sacrificing structural integrity.
The Westlake 447-040 Slip Cap is highly versatile and suitable for new installations, retrofits, or system maintenance. It can be used to close off unused pipe ends, protect pipe openings during construction, isolate sections of a system for repair, or provide a temporary seal during system upgrades. Its durable design ensures long-term reliability while maintaining a professional appearance and functional integrity in any piping system.
Precision manufacturing ensures that the slip cap fits accurately with standard 4-inch Schedule 40 PVC pipe, reducing the risk of leaks, misalignment, or joint failure. This precision guarantees a secure, professional-grade connection that performs consistently in residential, commercial, and industrial applications. Its combination of durability, smooth interior, and professional-grade construction makes it an essential component for any PVC piping system.
Applications for the 447-040 Slip Cap include pool and spa plumbing, irrigation and agricultural water systems, residential and commercial water supply lines, industrial fluid transport, and municipal piping systems. Its corrosion-resistant Schedule 40 PVC construction, smooth interior, and reliable design make it a trusted solution for sealing open pipe ends effectively.
