O-Rings manufacturer

As a manufacturer of O-Rings, we work hard to meet our customers requirements. An O-Ring is a round shaped ring, which serves as a seal to prevent liquids or gases from leaking. There are two types of such seals: static and dynamic. Dynamic seals usually oscillate or rotate.

The vast majority of O-Rings are used in force shunts. Operationg temperature depends on the rubber compound used and ranges from -70°C to +320°C. Assuming the ring is correctly installed, it can seal an ultra high vacuum at pressure up to 400 bar.

O-Rings are designed to reduce fluid and gas leaks to a minimum. O-Rings have many advantages, including:

- a reliable seal at different and varying pressures and temperatures and when in contact with liquids

- low surface pressure

- wide range of operating temperatures

- large pressure area

- easy to install and replace

- wide availability

- attracitve price

- a variety of materials, including NBR, HNBR, low temperature NBR, EPDM, Aflas(R), Silicone, Fluorsilicone, FKM & FFKM (perflourrubber).

As a O-Ring manufacturer, we have a wide range of tools for moulded O-Ring production: from the very smallest IDs (internal diameters), for instance for clocks/watches to custom sized O-Rings. We also produce large O-Rings made of cord and vulcanized at competitive prices.

Generally speaking O-Rings with an internal diameter (ID) <700 mm are molded, usually without tooling costs.

For O-Rings with internal diameters (IDs) between 700 and 850 mm, both options are possible.

O-Rings with an internal diameter (ID) >850 mm are usually shock-vulcanized
