Parker AS568 O-Ring 2-209 2-210 2-211 2-212 2-213 2-214 2-215 2-216 2-217 ID 17.04mm-29.75mm CS 3.53mm NBR FKM EPDM Coolant Resistant Gasket

Product Description:

The Parker 2-series O-rings are precisely molded elastomeric seals crafted according to the AS568A dimensional standards. This series includes dash numbers ranging from 2-201 to 2-284, all sharing a consistent cross-section of 3.53 mm (0.139"). The inside diameters span from approximately 7.59 mm for the 2-201 size up to 456.06 mm for the 2-284 size, accommodating a wide variety of gland dimensions—from small hydraulic fittings to large-scale industrial housings.

These O-rings are produced in three different elastomer families, each designed to meet specific fluid compatibility and temperature demands. The NBR (Nitrile) elastomer is suitable for general-purpose applications involving petroleum and hydraulic fluids. The FKM (Fluoroelastomer) variant is ideal for use with aggressive chemicals and in environments with elevated temperatures. Meanwhile, the EPDM (Ethylene Propylene) version is tailored for applications involving water, steam, and polar solvents.

Each elastomer compound offers dependable resistance against compression set and maintains sealing performance in both static and dynamic gland configurations. This ensures the O-rings deliver reliable and long-lasting sealing integrity across a diverse range of industrial applications.

Features:

These seals are molded to meet the standard dash-number tolerances of the AS568A specification, ensuring precise drop-in interchangeability for various applications.

The entire range from series 2-201 to 2-284 maintains a consistent cross-sectional thickness of 3.53 mm with a tolerance of ±0.10 mm. This uniformity simplifies the design of gland fittings and helps streamline spare parts planning.

NBR seals offer excellent resistance to petroleum-based oils, fuels, and hydraulic fluids. They typically operate effectively within a temperature range from approximately -34°C to +100°C (-30°F to +212°F).

FKM seals provide high resistance against aggressive chemicals, various acids, and fuels. Their standard service temperature range spans from about -25°C to +200°C (-13°F to +392°F).

EPDM seals are particularly suited for use with hot water, steam, and polar solvents. Their typical operational temperature range is approximately -50°C to +150°C (-58°F to +302°F).

This product line covers a broad size range, encompassing 84 different dash numbers from 2-201 up to 2-284. This corresponds to inside diameters ranging from roughly 7.59 mm to 456.06 mm.

Applications:

In the realm of hydraulic and pneumatic systems, NBR O-rings are commonly utilized. These seals are essential components for cylinder seals, valve bodies, and various fluid line connections, ensuring reliable performance and leak prevention.

For chemical processing applications, FKM O-rings are the preferred choice. They are specially designed to withstand the rigors of pump housings, reactor seals, and the transfer lines that handle aggressive media, offering excellent chemical resistance and durability.

When dealing with water and steam systems, EPDM O-rings provide an ideal sealing solution. They are widely used in boiler fittings, hot water valves, and sanitary process lines, thanks to their outstanding resistance to heat, steam, and water.

In general industrial assembly, AS568 2-series O-rings serve a versatile purpose. These O-rings are typically found in gearboxes, actuators, flanges, and standard gland sealing, delivering dependable sealing performance across numerous applications.
