TStücke

TStücke, commonly written as T-Stücke or T-fittings, are pipe fittings shaped like the letter T that join three pipe sections to form a branch in a pipeline. They allow one flow path to split into two or two flows to merge, enabling branching connections in plumbing, irrigation, and fluid systems. The central opening typically continues the main run, while the side opening creates the branch.

Types and materials vary by application. Common forms include threaded tees for metal piping, welded or soldered tees for copper and steel, and push-fit or solvent-weld tees for plastics such as PVC, CPVC, and PEX. Reducing tees have different bore sizes on the main and branch outlets. Materials range from brass and stainless steel to copper and various plastics, selected for chemical compatibility, pressure rating, and temperature range.

Connections and standards also differ. Tee fittings can use threaded connections (for example NPT or BSP), welded or soldered joints, compression, or push-fit methods. They are manufactured to standards established by organizations such as ISO, DIN, ASTM, and ANSI, depending on the material and region, to ensure interchangeability and performance.

Applications and use cases. T-Stücke are widely used in domestic plumbing, heating systems, irrigation networks, and pneumatic or hydraulic circuits. They serve to create branch lines, distribute fluids, or route multiple circuits from a single supply. In many systems, reducing tees or specialty versions are chosen to manage flow and minimize pressure loss.

Design considerations. Selecting a T-Stück involves matching nominal diameter, material compatibility, pressure and temperature ratings, and connection type. Proper installation is essential to avoid leaks, flow resistance, and stagnation zones, and to ensure long-term reliability.
