Metric O-Rings Are Now Available for Online Purchase
O-rings are the most common sealing product in the world; utilized across all types of sealing applications and industries. At its core, an O-ring is a circular sealing element with a circular cross section. Used effectively, an O-ring can seal practically all fluid, both liquid and gas. The wide range of potential liquids and gases that need to be sealed has necessitated the development of a wide range of materials.
GFS O-rings are manufactured in accordance with metric and imperial standards, such as: AS568, DIN, ISO 3601 and JIS. Additionally, O-rings can be manufactured to custom sizes upon request. Below are some of the most popular metric O-ring materials and durometers.
Metric NBR 70A O-Ring
This 70 durometer black nitrile (NBR) o-ring offers the best combination of properties across a variety of o-ring applications. Nitrile compounds perform well in gasoline, crude oil, power-steering fluid, hexane, toluene, water, water-based hydraulic fluids, and dilute bases, such as sodium hydroxide.
Because nitriles contain unsaturated carbon-carbon bonds in the base polymer, they are not suitable for exposure to ozone, sunlight, and weathering.
Metric NBR 70A Bagged O-Ring Pack
This 70 durometer black nitrile (NBR) o-ring offers the best combination of properties across a variety of o-ring applications. Nitrile compounds perform well in gasoline, crude oil, power-steering fluid, hexane, toluene, water, water-based hydraulic fluids, and dilute bases, such as sodium hydroxide.
Because nitriles contain unsaturated carbon-carbon bonds in the base polymer, they are not suitable for exposure to ozone, sunlight, and weathering.
Metric FKM 75A O-Ring
FKM 75A is a 75-Durometer General Purpose Black FKM O-ring material. This material has a broad spectrum of excellent resistance to a variety of chemicals and performs well at high temperatures.
Due to FKM's wide range compatibility, temperature range, low compression set, and excellent aging characteristics, FKM is considered one of the most significant elastomers developed in recent history.
Metric FKM 75A Brown O-Ring
This 70 durometer black nitrile (NBR) o-ring offers the best combination of properties across a variety of o-ring applications. Nitrile compounds perform well in gasoline, crude oil, power-steering fluid, hexane, toluene, water, water-based hydraulic fluids, and dilute bases, such as sodium hydroxide.
Because nitriles contain unsaturated carbon-carbon bonds in the base polymer, they are not suitable for exposure to ozone, sunlight, and weathering.
Metric FKM 80A O-Ring
FKM 80A is a 80-Durometer General Purpose FKM O-ring material. This material has a broad spectrum of excellent resistance to a variety of chemicals and performs well at high temperatures.
Due to FKM's wide range compatibility, temperature range, low compression set, and excellent aging characteristics, FKM is considered one of the most significant elastomers developed in recent history.
Metric FKM 80A O-Ring
