Parker O-Rings

If your business has ever needed a durable and reliable sealing method, it is likely that you turned to O-rings. O-rings are the most commonly used seals in the world since they are an affordable and reliable sealing option. An O-ring’s reliability depends on customers choosing the correct material and installation method for their projects.

Customers must choose the right product to enjoy the benefits that the O-ring has to offer, and this starts with Parker Hannifin. Parker Hannifin’s Engineered Materials Group has been a leading provider of reliable O-ring options for decades, and they have supported a range of industries. Parker partners with distributors like Wyatt Seal to provide the ultimate sealing solutions.

What are Parker O-Rings?

O-rings come in various materials and sizes, and customers should carefully consider the demands of the environment to ensure long-lasting performance. With a vast range of materials and designs, Parker O-rings ensure that customers do not have to settle for O-rings that only partially meet their needs. 

Seals provided by Parker EMG are superior because Parker is committed to providing its customers with optimal support. Parker offers an innovative Parker O-Ring Selector tool, which matches customers with O-ring options based on their size and material specifications. 

Types of Parker O-Rings 

Choosing the correct material is pivotal to maximizing the O-ring’s effectiveness. Parker offers an extensive inventory of seals and O-rings to address every project’s needs. The different types of Parker O-rings include: 

Fluorocarbon O-Rings

Fluorocarbon has excellent resistance to high temperatures, ozone, oxygen, mineral oil, synthetic hydraulic fluids, fuels, aromatics, and many organic solvents and chemicals. Special FKM compounds exhibit improved resistance to acids and fuels.

Hifluor™ O-Rings

Parker's Hifluor® has high purity with extremely low particle generation and ion content.  Translucent in color, the material is free of inorganic and black filler systems. The chemical and plasma etch resistance make it an excellent material for semiconductor applications.

Aflas® O-Rings

Parker's Aflas® has chemical resistance and is excellent across a wide range of aggressive media.

Parofluor O-Rings 

Parker’s Parofluor combines the elastic properties of elastomer compounds with the chemical and thermal resistance of PTFE. It offers excellent permanent elasticity compared to other perfluorinated elastomers. 

Silicone O-Rings 

Silicones (VMQ) have good ozone and weather resistance as well as good insulating and physiologically neutral properties as a whole. Silicone is ideal for the life science and consumer product markets. 

Fluorosilicone O-Rings

Parker's fluorosilicone (FVMQ) contains trifluoropropyl groups next to the methyl groups. The mechanical and physical properties are very similar to VMQ. However, FVMQ offers improved fuel and mineral oil resistance but poor hot air resistance compared to VMQ.

Nitrile O-Rings

Parker's Nitrile rubber (NBR) is the general term for acrylonitrile butadiene copolymer. The acrylonitrile content of nitrile sealing compounds varies considerably (18% to 50%) and influences the physical properties of the finished material. The higher the acrylonitrile content, the better the resistance to oil and fuel. NBR has good mechanical properties when compared with other elastomers and high wear resistance, but is not resistant to weathering and ozone. 

EPDM O-Rings

Parker's EPR copolymer ethylene propylene and ethylene-propylenediene rubber (EPDM) terpolymer are particularly useful when sealing phosphate-ester hydraulic fluids and in brake systems that use fluids having a glycol base.

Polychloroprene Neoprene® O-Rings

Parker's Polychloroprene was the first synthetic rubber developed commercially and generally exhibits good ozone, aging, and chemical resistance. It has good mechanical properties over a wide temperature range.

Polyacrylate O-Rings

Parker's polyacrylate ACM (acrylic rubber) has good resistance to mineral oil, oxygen, and ozone. Water compatibility and cold flexibility of ACM are significantly worse than with nitrile.

Ethylene Acrylate Vamac® O-Rings

Parker's EPR copolymer ethylene propylene and ethylene-propylenediene rubber (EPDM) are particularly useful when sealing hydraulic fluids and in brake systems that use fluids with a glycol base.

Butyl O-Rings

Butyl rubber (isobutylene-isoprene rubber or IIR) has a very low permeability rate and good electrical properties but poor short-term rebound.

Epichlorohydrin O-Rings

Epichlorohydrin rubbers offer low-temperature flexibilities, resistance to oils, fuel, and common solvents, and higher temperature resistance than NBR. It offers good weather ability and dynamic properties.
