endcaps

Endcaps are components used to close, seal, or terminate the end of a hollow part, tube, or enclosure. They provide protection from dust and moisture, serve as mounting points, or finish the appearance of assemblies. Endcaps appear across many industries and cover a range of forms and functions rather than a single standardized part.

In plumbing and piping, end caps seal the end of a pipe or tube. They are available in materials such as plastic (PVC, CPVC), metal, or composite, and in several connection styles, including slip-on, threaded, or push-fit. They stop flow, isolate sections of a system, or provide a test stub.

In mechanical engineering and motors, an end cap (often called an end bell) closes the ends of cylindrical housings, such as electric motors or linear actuators. End caps may house bearings, seals, or electrical terminals, and may be removable for maintenance or the integration of other components.

In retail, an end cap refers to the display at the end of a store aisle used for promotions and product visibility. End caps are often designed to attract consumer attention through layout, lighting, and signage.

In electronics and lighting, end caps connect and seal the ends of assemblies such as LED strips or module housings. They provide electrical contact, mechanical alignment, and environmental protection, and may be designed to facilitate assembly or service.

Endcaps thus represent a broad category of closure and termination components, adapted to the specific requirements of their application.
