When selecting hydraulic couplings, one critical factor to consider is their pressure rating. However, not all pressure ratings are the same. The existence of two distinct ratings—ANSI/ISO and Low Cycle, Non-Pulsating—reflects the different operational demands of hydraulic systems. Understanding these ratings and their test methods helps ensure safety, efficiency, and cost-effectiveness in your application.

When it comes to saving lives in critical situations, hydraulic rescue tools play an indispensable role. Known commonly as the “Jaws of Life,” these tools rely on high-pressure hydraulic systems to perform cutting, spreading, and lifting operations. A vital component in these systems is the quick coupling, which ensures reliable connections between hoses and tools, enabling rapid deployment and seamless operation. In this blog, we’ll explore the importance of quick couplings in hydraulic rescue tools, focusing on their high-pressure requirements and specialized design.
