Endteil

Endteil is a German term used in technical and engineering contexts to denote a component that terminates or completes an assembly at its end. It typically functions as a closing, protective, or mounting element and can take forms such as end caps, plugs, end plates, or end fittings. In many catalogs, the term covers interchangeable end pieces designed for quick assembly or disassembly.

In piping and tubing, Endteile are used to seal the end of a line, with common forms including blind plugs and end caps made of metal or plastic. In modular aluminum profile systems, Endteile cap the ends of extruded profiles to provide a finished appearance, prevent debris ingress, and sometimes serve as mounting points. In conveyor, rail, and similar systems, end fittings act as end stops or end brackets. The term also appears in electrical and cable-management contexts where end adapters close or terminate a run.

Material choices depend on the application, with options such as steel, stainless steel, aluminum, or various plastics. Design considerations include chemical resistance, temperature exposure, mechanical load, fit tolerance, and whether a seal or gasket is required. Endteile are typically designed to match a specific system standard, such as a particular thread size or profile dimension, to ensure compatibility.
