A USP O-ring is a specialized type of seal used in a variety of industries and applications to prevent the leakage of fluids or gases. What sets USP O-rings apart from other types of seals is their compliance with United States Pharmacopeia (USP) standards. These standards ensure that the materials used in the production of USP O-rings are safe and suitable for use in pharmaceutical and medical applications.

USP O-rings are designed to withstand high pressures, temperatures, and chemical exposure, making them ideal for use in critical applications where reliability is paramount. The materials used in USP O-rings are typically non-toxic and non-reactive, ensuring that they will not contaminate the products they are designed to seal.

USP O-rings come in a wide range of sizes and configurations, allowing them to be used in a variety of applications, including medical devices, pharmaceutical production equipment, and food and beverage processing systems. They are also frequently used in laboratory equipment, where their high level of reliability is essential to the accuracy of scientific experiments.
