Product Description:
The Parker 2-series O-rings are expertly crafted elastomeric seals that adhere to the AS568A dimensional standards. This series includes dash numbers ranging from 2-201 to 2-284, all maintaining a consistent cross-section diameter of 3.53 mm (0.139"). The internal diameters vary widely, beginning at approximately 7.59 mm for the 2-201 size and extending up to 456.06 mm for the 2-284 size, thus accommodating a wide variety of gland dimensions—from small hydraulic fittings to large-scale industrial housings.
These O-rings come in three distinct elastomer families designed to satisfy diverse fluid compatibility and temperature demands. The NBR (Nitrile) variant is ideal for general-purpose petroleum and hydraulic applications. FKM (Fluoroelastomer) is formulated for use with aggressive chemicals and higher temperature environments, while EPDM (Ethylene Propylene) is suited for applications involving water, steam, and polar solvents. Each material composition ensures dependable resistance to compression set and maintains sealing reliability in both static and dynamic gland configurations.
Features:
The AS568A series conforms precisely to dimensional standards, ensuring molded components meet the specified dash-number tolerances. This compliance guarantees seamless drop-in interchangeability with existing parts, simplifying maintenance and replacements.
All items within the 2-201 to 2-284 range feature a consistent cross-sectional diameter of 3.53 mm, with a tolerance of ± 0.10 mm. This uniformity across the series facilitates streamlined gland design and makes spare-parts management more efficient.
The NBR (Nitrile) option is designed for general-purpose applications, offering excellent resistance to petroleum-based oils, fuels, and hydraulic fluids. It typically operates effectively within a temperature span from approximately -34°C to +100°C (-30°F to +212°F).
For environments requiring heightened chemical resistance, the FKM (Fluoroelastomer) variant is ideal. It withstands aggressive chemicals, acids, and fuels, with a standard service temperature range of about -25°C to +200°C (-13°F to +392°F).
When dealing with hot water, steam, or polar solvents, the EPDM (Ethylene Propylene) elastomer is preferred. It performs reliably across a temperature range from roughly -50°C to +150°C (-58°F to +302°F).
This series provides broad size coverage, encompassing 84 different dash numbers from 2-201 to 2-284. The internal diameters covered range approximately from 7.59 mm to 456.06 mm, catering to a wide variety of application requirements.

Applications:
In the realm of hydraulic and pneumatic systems, NBR O-rings are extensively employed for sealing applications. These O-rings are ideal for cylinder seals, valve bodies, and connections within fluid lines, ensuring reliable performance under varying pressure conditions.
For chemical processing industries, FKM O-rings are preferred due to their excellent resistance to harsh chemicals. They are commonly used in pump housings, reactor seals, and lines that handle aggressive media, providing durability and chemical compatibility.
When it comes to water and steam systems, EPDM O-rings offer optimal sealing solutions. Their compatibility with boiler fittings, hot water valves, and sanitary process lines makes them a trusted choice for maintaining system integrity in these environments.
In general industrial assembly, AS568 2-series O-rings are widely utilized. These O-rings are essential components for sealing applications in gearboxes, actuators, flanges, and standard gland sealing, contributing to the overall efficiency and reliability of industrial equipment.
