What Are O-Rings?

O-rings are circular elastomeric seals designed to prevent leakage of liquids or gases between two surfaces in mechanical assemblies. When compressed within grooves under pressure, they create a tight, leak-proof seal essential for maintaining system integrity across harsh operating conditions.

As one of the most versatile and cost-effective sealing solutions available, O-rings are found in industries ranging from automotive and aerospace to oil & gas, medical devices, and food processing. Their simplicity, reliability, and low cost make them the preferred choice for millions of applications worldwide.

Lusida Rubber Products offers a large variety of O-Rings, from custom sizes and materials to AS568 and ISO 3601 Standard O-Rings.

Lusida supplies all sizes and materials, if you need a custom O-Ring we can make it.
