Cap, Slip PVC Schedule 40 8" (447-080)
$43.61
The 8" PVC Schedule 40 Cap (Part No. 447-080) is a large-diameter, white-body fitting designed to permanently close the open end of an 8" Schedule 40 PVC pipe or fitting. The slip (socket) connection accepts a solvent-cement joint to the pipe end, creating a rigid, leak-resistant termination that becomes a structural part of the pipeline once cured. As one of the most fundamental fittings in any PVC piping system, the cap serves a straightforward but essential function — sealing a pipe end against flow, pressure, and ingress wherever the line terminates, is temporarily capped during staged construction, or requires a closed end for pressure testing.
At 8", this cap is a substantial fitting most commonly specified in municipal water and wastewater infrastructure, large-scale irrigation systems, industrial process piping, and stormwater management applications where large-diameter PVC is the pipe of choice. End caps at this size are used at dead-end mains, system termination points, stub-out locations for future expansion connections, and test points where a section of pipe must be isolated and pressure tested before the system is fully commissioned.
The permanent nature of a solvent-cemented cap is an important specification consideration. Unlike a threaded plug or a mechanical end cap that can be removed without cutting, a solvent-cemented PVC cap creates a bond that is integral to the pipe wall — removal requires cutting the pipe. For applications where future access to the pipe end is anticipated, a threaded cleanout plug and adapter, a mechanical end cap, or a flanged blind assembly may be the more appropriate specification. Where a permanent, low-profile termination is the requirement, the slip cap is the correct and most economical choice.
Manufactured from Type I, Grade I PVC compound, this fitting conforms to ASTM D2466 dimensional standards and is compatible with Schedule 40 PVC pipe and solvent cements meeting ASTM D2564.

- Pressure Rating: Standard Schedule 40 rating for 8" pipe (lower PSI at larger diameters; ideal for non-pressurized or low-pressure systems)
- Standards: ASTM D1784
- Part Number: 447-080
- Product Family: Schedule 40 PVC
- Carton Quantity: 4
- Pallet Quantity: 96
Typical Applications
This 8" PVC Pipe Cap is widely seen across plumbing, construction, and infrastructure projects that need a consistent way to terminate, isolate, or protect large pipe runs.
The most common use cases include:
- Industrial and commercial water lines
- Agricultural irrigation mains and distribution systems
- Aquaculture tanks, raceways, and filtration loops
- Municipal drainage and stormwater systems
- Large pump suction or discharge pipelines
- Construction-phase protection for exposed pipe ends
- System pressure testing and temporary isolation
- Permanent or future-expansion line terminations
Thanks to its slip-style socket design, installation is quick and secure even for high-capacity systems.
Installation & Handling Tips
Large-diameter Schedule 40 components require proper preparation to achieve a reliable, watertight seal:
- Clean and dry both the pipe end and cap socket before installation
- Apply PVC primer, then solvent cement per manufacturer guidelines
- Push the cap fully onto the pipe with firm, even pressure; large fittings may require a strap wrench or assistance
- Support the pipe to prevent sagging or torque while the cement cures
- Allow full cure time before testing the system
- Do not exceed PVC temperature or pressure limits
- Note: Not designed for compressed air or gas systems
- Handle with care: 8" fittings are bulky and can be heavy
