Rubber rings are a reliable and simple sealing solution for joints. The product requirements are set out in GOST 9833. Key advantages include:

  • easy installation
  • long service life
  • retention of the original properties after several assembly and disassembly cycles

Today, round-section sealing rings, commonly known as O-rings, are among the most widely used sealing products. Their popularity is due to their extensive application in fuel, hydraulic, lubrication, and pneumatic units, as well as in various regulators, valves, and moving or fixed joints. Although thermoplastics and other materials may also be used to manufacture round-section sealing rings, practical experience shows that rubber-based products are often the most suitable choice.

Round-section rubber sealing rings manufactured in accordance with GOST 9833-73 can be used effectively for sealing both static joints and connections exposed to dynamic loads. The product range covers a broad selection of sizes. These round-section rubber sealing rings are designed for use as components in hydraulic and pneumatic equipment.

Operating conditions for rubber sealing rings

The product can be used in equipment under the following conditions:

  • temperature range from -60°C to +200°C
  • pressure in systems with static joints: up to 50 MPa
  • pressure in systems with moving joints: up to 32 MPa

Round-section rubber rings are resistant to many media, including petrol, oils, fuels, water, and similar substances. The products offer high wear resistance and are designed for long-term use.
