TKT-PU4 Union Straight Push-In Pneumatic Fitting AIRMIXS
The TKT-PU4 is a compact equal union straight push-in pneumatic fitting engineered to connect two 4 mm outer-diameter pneumatic tubes in a continuous inline run. Ideal for precision pneumatic controls, micro-actuation, and tight enclosure routing, this straight coupling provides a seamless, tool-free connection point.
Equipped with high-precision internal stainless steel lock-claws and ergonomic release collars on both ends, it ensures a secure, vibration-resistant, zero-leak seal without crimping or scoring the tube surface. Its ultra-compact profile enables quick maintenance, easy inline tube extension, and organized pneumatic plumbing in modern automated systems.
