Parker AS568 O-Ring 2-201 2-202 2-203 2-204 2-205 2-206 2-207 2-208 ID 4.34mm-15.47mm CS 3.53mm NBR FKM EPDM Ozone Resistant Seal For Water Valve And Steam Control Component Assembly

Product Description:

The Parker 2-series O-rings are precisely molded elastomeric seals that adhere to the AS568A dimensional standards. This series encompasses dash numbers ranging from 2-201 to 2-284, all maintaining a consistent cross-section thickness of 3.53 mm (0.139 inches). The inside diameters vary significantly, starting from approximately 7.59 mm for the 2-201 size and extending up to 456.06 mm for the 2-284 size. This extensive range accommodates a wide variety of gland sizes, from small hydraulic fittings to large-scale industrial housings.

These O-rings are offered in three different elastomer families, each designed to suit specific fluid compatibility and temperature requirements. The NBR (Nitrile) variant is ideal for general-purpose applications involving petroleum and hydraulic fluids. Meanwhile, the FKM (Fluoroelastomer) type delivers superior performance in environments with aggressive chemicals and higher temperature conditions. Lastly, the EPDM (Ethylene Propylene) O-rings are well-suited for applications involving water, steam, and polar solvents.

Each elastomer compound ensures dependable resistance to compression set, maintaining effective sealing performance over time. They are engineered to provide sealing integrity in both static and dynamic gland configurations, making Parker 2-series O-rings a versatile and reliable choice for a broad spectrum of sealing applications.

Features:

The AS568A series is manufactured to meet precise dimensional standards, adhering to the standard dash-number tolerances. This ensures seamless drop-in interchangeability with existing components, facilitating easy replacements and consistent performance.

A uniform cross-section of 3.53 mm (± 0.10 mm) is maintained throughout the 2-201 to 2-284 series. This consistent dimension simplifies the design of glands and assists in efficient spare-parts management by reducing variability across the range.

The NBR (Nitrile) material option serves as a general-purpose choice due to its excellent resistance to petroleum oils, fuels, and hydraulic fluids. It performs reliably within a temperature range of approximately -34°C to +100°C (-30°F to +212°F), making it versatile for many industrial applications.

For applications requiring high chemical resistance, the FKM (Fluoroelastomer) variant offers outstanding durability against aggressive chemicals, acids, and fuels. It is suitable for service conditions ranging roughly from -25°C up to +200°C (-13°F to +392°F).

The EPDM (Ethylene Propylene) grade is preferred for use with hot water, steam, and polar solvents. It provides dependable performance within a temperature window of about -50°C to +150°C (-58°F to +302°F), making it ideal for water and steam service environments.

Covering a broad spectrum of sizes, this series includes 84 dash numbers, from 2-201 to 2-284. The internal diameters range approximately from 7.59 mm to 456.06 mm, offering extensive options for various sealing requirements.

Technical Parameters:

Applications:

In hydraulic and pneumatic systems, NBR O-rings are widely used due to their excellent sealing capabilities. These O-rings are typically applied in cylinder seals, valve bodies, and fluid line connections to ensure reliable performance under various operating conditions.

For chemical processing applications, FKM O-rings are preferred because of their superior resistance to aggressive chemicals. They are commonly found in pump housings, reactor seals, and media transfer lines that handle corrosive substances.

When dealing with water and steam systems, EPDM O-rings provide effective sealing solutions. They are suitable for use in boiler fittings, hot water valves, and sanitary process lines, where heat and moisture resistance are critical.

In general industrial assembly, AS568 2-series O-rings serve a versatile purpose. These standard gland sealing rings are extensively used in gearboxes, actuators, flanges, and other industrial components requiring reliable sealing.
