High temperature quick couplings HTI

In response to demanding requirements in plastic injection, Stäubli developed the HTI, a new coupling that can withstand temperatures up to 300°C. HTI couplings meet all safety requirements and feature a double-action locking system. Designed to be maintenance free, the quick coupling does not have a seal in the fluid stream.

Applications: Temperature control in a variety of sectors including plastic injection molds, metallurgical (die casting, iron and steel), glass, composites, aluminum and magnesium, pressure die-casting and more.
