The TKT-PU6 is an industrial equal union straight push-in pneumatic fitting designed to join two 6 mm outer-diameter tubes in a smooth, continuous inline connection. Engineered for instant, tool-free assembly, this straight connector provides a reliable method for extending air lines or repairing tubing in pneumatic control circuits.

Featuring internal stainless steel lock-claws and user-friendly release collars on both ends, it maintains a firm, vibration-proof, leak-free seal while preserving the outer walls of the tubing. Its lightweight, compact body simplifies tubing management and enables clean, space-saving installations across automated systems and machinery panels.
