5" Cap, Slip PVC Schedule 40 (447-050)
$12.17
The 447-050 is a 5" PVC Schedule 40 cap in a slip configuration, providing a permanent solvent-weld termination for a 5" pipe end, fitting spigot, or stub-out. The slip socket accepts standard 5" pipe or a spigot-end fitting for solvent cement bonding, sealing the end of a large-diameter PVC line cleanly and permanently — whether closing off a dead-end run, terminating a supply main, capping a distribution header during phased construction, or blanking an unused outlet in a large-diameter manifold or fitting body.
At the 5" size, the 447-050 is a large-diameter fitting by PVC standards — appearing in the kind of high-volume supply mains, primary distribution headers, and municipal or agricultural infrastructure where a capped end represents substantial system capacity being held or terminated. The solvent-weld slip construction makes this a fully permanent termination: once cemented, the cap becomes a monolithic part of the pipe assembly with no mechanical joints, threaded interfaces, or gaskets to maintain, loosen, or inspect over time.
The permanent nature of the slip cap is its primary characteristic and the key consideration in fitting selection. Where a threaded cap (FPT style) can be removed and reinstalled with a strap wrench, the slip cap creates an irreversible solvent-weld joint — making it the correct choice when the termination is intended to be permanent, when a flush end profile is preferred over a threaded stub, or when the system design does not anticipate any future access or branch connection at the capped end. For large-diameter systems where the capped end may need to be opened for future expansion, a threaded cap or a mechanical end plug should be evaluated as alternatives before committing to a solvent-weld termination.
Schedule 40 PVC provides the pressure ratings and chemical resistance appropriate for the broad range of commercial, agricultural, and municipal applications served by 5" PVC piping — at a cost-effective wall thickness suited for systems where the higher pressure ratings of Schedule 80 are not required. The white color is the standard identifier for Schedule 40 PVC, distinguishing it clearly from gray Schedule 80 components in mixed systems.
Solvent cement installation follows standard PVC practice — clean, prime, and cement both mating surfaces per ASTM D2564 procedures. At the 5" size, use of a heavy-bodied PVC solvent cement is required to ensure adequate fill and bonding across the large socket surface. Apply cement generously and evenly to both the pipe end and the cap socket, seat the pipe fully with a quarter-turn twist, and hold firmly for the initial set period. Confirm orientation is correct before cementing, as there is no adjustment once the cement engages at this diameter.

- Irrigation & Agriculture — Permanent termination of 5" pressurized mainline supply runs, primary distribution headers, and field supply mains in large-scale agricultural and landscape irrigation systems where dead-end runs or phased construction require a large-diameter cap at the system boundary
- Municipal Water Distribution — Permanent end-of-main terminations in Schedule 40 PVC water distribution infrastructure where 5" supply mains are capped at system boundaries, future extension points held in reserve, or dead-end runs sealed in permanent buried installations
- Water & Wastewater Treatment — Termination of unused or end-of-run ports on large-diameter treatment plant distribution piping, process water supply mains, and pump station headers where a permanent solvent-weld cap is required at the pipeline terminus
- Commercial & Industrial Plumbing — Permanent termination of 5" cold water mains, primary supply headers, and large-diameter mechanical room distribution piping where a flush, permanent end cap is specified at the system boundary or dead-end run
- Industrial Processing — Capping dead-end headers, unused manifold outlets, and terminal points in 5" Schedule 40 process water and utility piping where a permanent, pressure-rated solvent-weld termination is required
- Aquaculture & Aquatics — Permanent termination of large-diameter recirculating system primary headers, filter manifold outlets, and main distribution mains in large-scale systems where 5" Schedule 40 PVC is used throughout
- Drainage & Stormwater — End-of-run terminations in large-diameter Schedule 40 PVC drainage and stormwater collection piping where a permanent solvent-weld cap seals the pipeline terminus in buried or enclosed installations
- Fire Suppression Support Systems — Permanent termination of 5" Schedule 40 PVC water supply lines and distribution headers in fire suppression support infrastructure where large-diameter pipe ends require a permanent, pressure-rated cap at system boundaries

5" Cap, Slip PVC Schedule 40 (447-050)
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.
