pressure rating

**Pressure Rating**

The term “pressure rating” refers to the maximum pressure that a component, such as a pipe, valve, flange, or fitting, can safely withstand under specified conditions. It is a critical specification in industries like plumbing, HVAC, manufacturing, and engineering to ensure system safety and performance. Pressure ratings are usually expressed in units such as PSI (pounds per square inch), bar, or Pascal, and are determined based on material strength, design, and testing standards. Understanding the pressure rating helps in selecting the right equipment for your application and prevents failures due to overpressure.
