The TKT-PU12 is a heavy-duty equal union straight push-in pneumatic fitting engineered to join two 12 mm outer-diameter tubes in a seamless, high-flow inline configuration. Designed for rapid, tool-free push-to-connect assembly, this straight coupling provides a high-reliability solution for extending major air lines, splicing tubing, or maintaining industrial air networks.

Equipped with reinforced internal stainless steel lock-claws and user-friendly release collars on both ends, it delivers a high-integrity, vibration-proof, zero-leak seal while protecting the tubing wall from scoring. Its durable, compact housing ensures clean, efficient tube routing across high-demand automated production lines and central air distribution networks.
