A pipe end cap is a type of fitting used to seal the end of a pipe. It is typically used when a pipe is no longer needed or is temporarily disconnected from a system. The end cap fits over the end of the pipe and is secured in place using screws, clamps, or other attachment methods. Pipe end caps are available in a range of materials, including metal, plastic, and rubber. The material used depends on the application and the type of pipe being capped. For example, metal end caps may be used for industrial piping systems, while plastic or rubber caps may be used for plumbing or irrigation systems.

End caps may also be designed to provide additional functionality, such as preventing the buildup of debris or allowing for drainage. Some end caps may have a vent or drain hole to allow for the release of pressure or fluids. Others may be designed with a threaded connection to allow for the attachment of additional fittings or accessories. Overall, pipe end caps are an important component in piping systems, as they provide a secure and reliable seal to prevent leaks or contamination.
