The O-Ring is the most simple and versatile seal as well as the cheapest one in the market. Its shape has permitted the O-Ring to become the top seal in lots of industrial fields such as fittings, car industry, hydraulics, pumps, tubings…
The widespread use of O-Rings has enabled us to develop large-scale production processes with a consequent drop in manufacturing costs. The O-Ring´s circular symmetrical section means it can be used in both single or double effect applications with any type of fluids due to its elastomeric composition.
The radial or axial clamping method gives it a sealing property which, added to the pressure of the system itself, creates a sealing force which increases with the aforementioned pressure. In other words, in conditions of pressure the O-Ring acts as if it were a fluid, featuring a high surface tension and distributing all the pressure around in a uniform manner.
Its main benefits include simple assembly, simple housing designs, low cost, small size, excellent quality/price ratio, durability, and the wide range of materials in which O-Rings are available.
