This range of quick couplings, dedicated to high flow rates, stands out for its excellent durability and clean break technology. They have particularly robust bayonet locks, and can be relied upon to ensure perfect, permanent sealing during connection and disconnection. Ergonomic design, including a hand wheel and automatic locking, makes handling easy. Thanks to all these characteristics, Staubli’s non spill connectors are an efficient solution for several applications such as bulk chemical and petrochemical, special chemical, biotechnology, etc.
