verbandstuk

Verbandstuk is a Dutch term used primarily for a connecting piece that joins two components in a system, most often in piping, tubing, or ductwork. In technical and industrial texts it is often used interchangeably with verbindstuk or fitting. The function of a verbandstuk is to enable alignment, sealing, or branching of a flow path, and to accommodate different materials and sizes.

Verbandstukken come in a range of shapes and materials. Common forms include hoekstuk (elbow), T-stuk (tee), kruisstuk (cross), koppelstuk (coupling), and afsluitstuk (end cap). They may be threaded, soldered, welded, crimped, or connected by compression or push-fit methods. Materials include metal such as brass, copper, steel, and cast iron, as well as plastics like PVC, CPVC, and PEX.

Installation considerations cover compatibility with fluid, pressure, temperature, and the system's existing standards. Proper sealing, thread compounds, or gaskets are typically required; some fittings are designed for soldering, welding, or crimping. In plumbing, verbandstuk selection also depends on corrosion resistance and aging requirements.

Outside of engineering, the word also appears in medical Dutch to denote a bandage piece that secures a dressing or applies compression. The term derives from verband (bandage) and stuk (piece).
