Use the O-Ring quick search to find your match.
Alternatively you can search by 'AS/BS reference' or 'Chemical Compatibility' Use the 'Material Info' tab to access material datasheets and specification.
Search our extensive range of o-rings by entering the BS reference (also known as AS or Dash Number) in the box below. You can use the full reference as in 'BS001' or just the number, '001'.
If you are uncertain of the material you require choose 'Any Material', otherwise select it from the drop-down menu.
Polymax can also supply custom o-rings e.g. different sizes, materials, hardnesses and colours.

Description
NBR (Nitrile) is the most cost effective and commonly available O-ring material. Ideal for use as seals for pumps, drive belts, and other general engineering applications in the hydraulic and pneumatic industry.
NBR is good for applications where the O-ring is exposed to fats, greases and animal or vegetable oils.
For applications requiring contact with diesel or temperatures higher than 120°C you may wish to consider Polymax FKM (Viton®) O-rings.

Description
FKM (Viton®) O-rings have excellent chemical resistance and can be used at temperature range of between 15°C and 200°C. Although generally more expensive than NBR (Nitrile) O-rings, FKM has found wide acceptance in the aircraft, automotive and chemical industries.
The terms FPM, FKM and Viton® can lead to incorrect interpretations. These designations stand for one single base material: fluorocarbon rubber.
Polymax is also able to supply specially compounded FKM O-rings meeting Norsok M710, FDA, USP Class VI, UL94 V0, EN549, Viton® A, B, G, GF, GLT, GFLT, ETP standards on special request. Please contact us for further information.

Description
EPDM rubber is a terpolymer of ethylene, propylene and diene monomers.
General purpose EPDM O-rings are manufactured using a sulphur based curing system, these are suitable for use up to +120°C whereas peroxide cured
Polymax peroxide cured EPDM O-rings have a series of approvals including ACS, WRAS, KTW, EN 681-1. Please contact us for further information.

Description
Silicone (VMQ) rubber contains methyl and vinyl groups attached to the main silicone chain. Silicone O-rings are characterised by excellent resistance to temperature extremes and thermal cycling. Silicone rubber compound does not impart odour or taste, which makes it suitable for many food and pharmaceutical applications.
Silicone rubber however, has poor mechanical properties as compared to other elastomers and for this reason silicone O-rings are generally not used in dynamic applications. It is not suitable for use with silicone O-ring lubrication, PTFE alternatives should be used instead.

Description
PTFE is a highly resilient O-ring material unaffected by virtually all known acids, alkalis and solvents. It is tough, abrasion resistant and capable of withstanding temperatures between -200°C to +250°C. It also possesses outstanding weather, ozone and electrical resistance. For this reason, it is the O-ring of choice for use in aerospace, food, pharmaceuticals and telecommunications industries.
PTFE O-rings could be a more economical alternative to FFKM materials, but they are not easily compressed and have little memory to be able to return to their original form. This can be a disadvantage if under permanent strain and may not create the best lasting seal.

Description
Chloroprene (or Neoprene / CR) was one of the first developed synthetic compounds, invented by DuPoint™ scientists in 1930. Chloroprene is a good multi-purpose material, it exhibits fair oil resistance and good ozone and weather resistance. A combination of both these properties is usually not found in other commonly available elastomers like NBR and EDPM.
Chloroprene is often used in refrigeration systems due to the excellent resistance to refrigerants such as Freon® (R12, R13, R21, R22, R113, R114, R115, R134A) and ammonia.
