O-rings, red

It is hard to imagine a world without these elastic, ring-shaped gaskets, which are made out of rubber, being used as a means to prevent liquids or gases from escaping past the joints of joined pieces of material. They are found in practically every branch of industry but also in every household, for example, in the water faucet. The name O-ring comes from the round shape of a cross-section of the rings. Because O-rings functioning as gaskets must fit perfectly, they come in tens of thousands of sizes and are made of numerous different materials so as to satisfy a wide variety of needs. One of the smallest known O-rings is used in the making of Swiss watches and has the dimensions 0.70 × 0.20 mm. Among the largest O-rings are the gaskets for the space telescopes or nuclear reactors, which have a diameter of over ten metres.

Modulor, however, after thinking about it for a long time (one second!) has decided not to try and supply these areas of use with their maximum precision demands. This universal ring tends to suggest a variety of uses that do not conform to the ways for which it was intended to be used. For instance, as a means to bundle up rods or close up bags or an O-ring, when rolled tightly over a rod, can be used to prevent other things from sliding past it. Balls can be made to stay in place by placing them on the right sized ring serving as a stand. The extremely heat resistant O-rings that are made out of transparent or red silicone can serve as simple and aesthetic pan hot-pads. For jewellery work the very small rings have especially interesting possibilities.

The O-rings that we have on offer are made out of different kinds of caoutchouc through hot injection mould or press mould processes and are both jointless and seamless as a result of vulcanization (cross-linking). We do not carry O-rings that are made from round cords whereby there is a joint where the ends come together that is too obvious to miss.

Please note: Our rings are top gasket quality rings that exhibit the craftsmanship involved in their production. The purpose for which they are intended does not include their being exposed to UV radiation or the effects of light. As is usually the case with elastomers, after a certain amount of time the physical characteristics can undergo changes, the intensity of which depends on the external conditions. They can, for instance, harden, soften, develop cracks – those kinds of things. Unfortunately we are not able to make any predictions as to the durability/life of the rings neither in regards to their intended use nor for other uses under other conditions like, for example, exposure to weather.
