Elastomers and Compounds
Elastomer, a word formed by combining elastic and polymer, refers to any number of rubber compounds that change shape in response to stress such as extreme temperatures, pressure, or chemical reactions. Rubbers compounds can be both natural or synthetic depending on the nature of their origination. Any of the 32 synthetic rubbers, such as Ethylene Propylene Rubber and Fluorocarbon Rubber, provide effective protection from leakage and unwanted exposure in high-quality sealing applications.
This reliable design is the result of a functional crosslinked molecular network of polymer chains that are vulcanized into a more durable, elastic form. It is this process of vulcanization that dramatically changes the properties of reactive polymers yielding to its optimal sealing form. Parker focuses on maintaining consistent temperatures throughout the process with disciplined monitoring and follow-up assessments after curing is complete.
The compounds that compose Parker's O-rings are a mixture of base polymers, added chemicals, and a blend of specific ingredients that, in combination, provide adequate means for desired sealing performance. Our complete inventory of Parker Nitrile Rubber (N674-70), Fluorocarbon Rubber (V1226-75), Ethylene-Propylene Rubber (E540-80, E515-80, E740-75, EM163-80), and Silicone Rubber (S604-70) O-rings provides comprehensive solutions for your sealing needs.
Types of Parker O-Ring Compounds
Parker Nitrile Rubber O-Rings
Parker's N674-70 O-rings have tremendous heat resistance, excellent mechanical properties, and a recommended temperature range of -30°F to 250°F.
Parker Silicone Rubber O-Rings
Parker's S604-70 O-rings have good insulating and physiologically neutral properties and are known for excellent resistance to ozone, aging, and weather.
Parker Fluorocarbon Rubber O-Rings
Parker's V1226-75 O-rings are characterized by notable resistance to high temperatures, as well as ozone, oxygen, mineral oil, and many organic solvents and chemicals. Low-temperature resistance is defined at approximately -15°F (-26°C).
Parker Ethylene Propylene O-Rings
Parker's EP O-rings include four in-stock products that provide consistent performance: E540-80, E515-80, E740-75, and EM163-80. These compounds are particularly useful in sealing phosphate-ester hydraulic fluids and glycol- or silicone-based brake fluids.
