provide flexible, 360° rotating connections for air lines. These push-to-connect swivel joints (e.g., 4-12mm tube to M5-1/2″ thread) feature durable brass construction with built-in bearings for smooth, low or high-speed rotation. Ideal for robotics, moving machinery, and applications requiring freedom of pneumatic tube movement.
