447-050 5" Slip Cap PVC SCH 40

Technical Specifications

The 5" Slip Cap PVC SCH 40 (Part #447-050) is designed to close the end of a 5-inch Schedule 40 PVC pipe using a secure solvent-weld socket connection. Made from white, rigid Schedule 40 PVC, this cap offers strong resistance to corrosion, chemicals, and outdoor exposure. Typically supporting a pressure rating of about 165 PSI at 73°F (varies by system design), the cap is suitable for cold-water distribution lines and low-temperature applications with a maximum service temperature of 140°F.

Schedule 40 PVC fittings like this model meet ASTM D1784 material standards and NSF 14/61 requirements for potable water systems. Compatible only with 5" nominal Schedule 40 PVC pipe, this cap provides a reliable permanent seal for residential, commercial, and industrial projects.

Typical Applications

A 5" PVC Slip Cap is commonly used to close off large-diameter lines in a wide range of plumbing and water-handling systems. Plumbers and construction teams count on this fitting for:

• Agricultural irrigation mains
• Commercial and municipal water distribution
• Pool and spa circulation systems
• Industrial water and fluid-handling networks
• Drainage, venting, and waste piping
• Temporary water lines on construction sites

Slip caps are ideal whenever a permanent closure is needed; they’re often chosen over threaded caps when ongoing access is not required or when installers prefer a smooth, solvent-welded finish that reduces leak points. They also help protect pipe ends from debris or damage during transport or staging.

Installation & Handling Tips

For a proper solvent-weld connection, clean the pipe end and the inside of the cap before priming. Use a PVC primer and solvent cement rated for Schedule 40 fittings. After applying cement, insert the pipe fully into the socket and hold it in place for about 20–30 seconds to prevent movement as the bond forms. Allow the joint to cure completely before pressure testing or placing the line back into service.

This fitting is designed for permanent installations, so it should not be used where repeated removal is expected. Avoid using Schedule 40 PVC in compressed-air systems or high-temperature environments, and only ever pair this cap with matching 5" Schedule 40 PVC.
