reducer O-ring kit Vittorazi Atom80

An O-ring, also called a toroidal seal or toroidal seal, is a type of rubber seal. Its circular shape resembles a ring, with a circle-shaped cross section. This seal is usually made from elastomeric materials such as silicone or fluorocarbon.

O-rings are used to provide a seal between two surfaces, such as moving parts, axles or pipes. They are designed to prevent leaks of liquids or gases by creating a tight barrier between parts, even when there are variations in pressure or relative movement between contacting surfaces.
