O-Rings, the simplest, most versatile and cheapest seal on the market
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.
O-Rings, own approvals
In addition to its own approvals, JIOrings also provides O-Rings with approvals obtained by its suppliers: drinking water, gas, flame or food. You will find a list of the main approved compounds in the Approvals section.
Quality control
The DIN 3371 and the ISO 3601 are the commonly used international Standards to define O-Rings tolerances.
After production, the O-Rings must be subjected to several tests in order to control the properties of sizes and quality are suitable: for that, as minimum, hardness tests, sizes checking and surface control are performed.
O-Rings able to detect metal
We also offer a wide range of compounds able to detect metal, a safe and cost-effective solution to ensure its use in the food and pharmaceutical industries or any other one that needs a high level of safety. Metal detectable O-Rings are available only on request. More information.
