3M - Seals and Gaskets

Seals and gaskets are essential components used to prevent the leakage of fluids (liquids or gases) between two surfaces. They are designed to maintain a tight seal under different operating conditions, such as pressure, temperature, and environmental exposure.

One of the most common types of gaskets is the O-ring, which is a seal used in mechanical systems. These are used in hydraulic systems and on pipe, pumps, and cylinders. Another common seal is the oil seal, which is designed to prevent lubrication from leaking and to prevent two or more fluids from meeting at the joint of moving parts. Key elements to consider when selecting seals and gaskets are outside diameter, inside diameter, material, and whether the operation involves high heat.
