O-Ring cord is used for custom manufacturing of O-rings for any diameter. It is highly useful in cases where, for any reason, standard O-rings do not fit a particular application. It’s very common to purchase O-Ring cord and adjust it to the correct size needed by the company.
This adaptability makes them very versatile when used in any industrial process requiring a good seal. Like O-rings, they are a popular solution for static sealing.
O-Ring cord is used to create a custom O-ring. This O-ring created from the cord serves as the seal between two parts that need to certify their seal for proper functioning. In industrial processes involving fluids, whether in the form of gas or liquids, a hermetic seal must be certified for several reasons:
The first thing to consider when replacing an O-ring with a cord is that careful attention is needed when cutting to the exact size. It is not recommended to use the O-ring to be replaced as a reference for this initial step, as it will be elongated and deformed. Once you have the O-Ring cord of the appropriate diameter, you need to take the exact measurement and make a straight (perpendicular) cut to the cord so that the two faces fit together properly during bonding. To bond the two faces, you need to use Cyanoacrylate adhesive.
This adhesive should be used to bond the two faces of the O-Ring cord, forming a seal. It dries quickly, and it’s important to ensure no adhesive residues are left on the seal (for it to function correctly). You can sand the seal with sandpaper to remove any adhesive residues.

Entre los materiales más utilizados en la industria se encuentran el NBR y VQM. También existen de otros materiales, no obstante, en este post vamos a analizar las características de estos materiales
El caucho NBR es el más utilizado para las juntas de estanqueidad estándar, debido a que reúne las características óptimas para ser una solución de garantía.
En cambio, no es un material resistente a:
Silicone Rubber (VMQ)
When it comes to silicone rubber (VMQ), it is worth highlighting that it performs very well with atmospheric agents, displaying great resistance to fluids and gases such as ozone, radiation, etc. Silicone is particularly suitable for use in sectors like the food industry due to its high resistance to radiation and high temperatures. As a disadvantage compared to NBR rubber, one can mention the lack of mechanical properties in silicone, which makes it more often directed towards static sealing.
