All about O-Rings

- Categories : O-Rings

Variety, quality, and custom manufacturing when standard options don't work

We are the seal supplier you're looking for. With over 20 years of experience, we specialize in O-rings for various applications and industrial sectors.

O-rings, also known as O rings or orings, are a type of mechanical seal in the shape of a ring that ensures reliable sealing in systems subjected to different pressures. Thanks to their design, these rings can be used in both static and dynamic applications under high pressures and temperature ranges from -15ºC to +320ºC, ensuring necessary sealing.

We have a wide and varied catalog of O-rings (over 42 million in stock), where you can find a large selection of sizes, materials, hardness (from 30 to 98 Shore A), certifications (suitable for food and/or potable water contact), and colors.

We are ready to meet any requirements for sealing systems.

Available Materials

At JIOrings, in addition to the most demanded materials (NBR, FPM Viton, VMQ Silicone, EPDM...), we also offer O-rings in less common materials used for applications requiring special characteristics such as chemical resistance, extreme temperatures, or contact with specific substances:

• Teflon (PTFE): Teflon O-rings offer excellent chemical and thermal resistance. Ideal for the chemical and pharmaceutical industries, and for extreme temperature environments.

• Perfluoroelastomers (FFKM): These FFKM O-Rings combine flexibility and high chemical resistance. Perfect for oil and gas, aerospace, and chemical processing industries.

• Polyurethane (PU): Polyurethane O-rings are highly resistant to wear and abrasion. Used in hydraulic and pneumatic systems for heavy machinery.

• HNBR (Hydrogenated Nitrile): HNBR O-rings provide great resistance to heat, ozone, sunlight, and fuels. Used in the automotive industry, especially in fuel and transmission systems.

• Aflas (FEPM): Aflas O-rings resist acids, bases, and amines, and withstand high temperatures. Excellent for the oil, gas, and power generation industries.

• CR (Neoprene): Neoprene O-rings are resistant to weather, ozone, light oils, and certain chemicals. Ideal for marine applications, refrigeration, and industrial exteriors.

These less common materials represent specialized solutions for applications requiring unique properties where conventional materials cannot ensure leak-free sealing.
