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. Operating temperature depends on the rubber compound used and ranges from -55°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
We produce metric O-Rings, AS586 O-Rings, BS Standard O-Rings, JIS O-Rings, non standard sized O-Rings
