Parker AS568 O-Ring 2-226 2-227 2-228 2-229 2-230 2-231 2-232 2-233 2-234 ID 50.39mm-75.79mm CS 3.53mm NBR FKM EPDM Anti Gas Permeation Gasket

Product Description:

The Parker 2-series O-rings are elastomeric seals that are precision-molded in accordance with the AS568A dimensional standards. This particular series includes dash numbers ranging from 2-201 to 2-284, all consistently featuring a cross-section size of 3.53 mm (0.139 inches). The inside diameters of these O-rings vary significantly, starting from approximately 7.59 mm for the 2-201 model and extending up to 456.06 mm for the 2-284 model, allowing them to fit a wide range of gland sizes, from small hydraulic fittings to large-scale industrial housings.

To accommodate diverse fluid compatibility and temperature requirements, these O-rings are offered in three distinct elastomer families. The NBR (Nitrile) option is suited for general-purpose applications involving petroleum products and hydraulic systems. Meanwhile, the FKM (Fluoroelastomer) variant is designed to withstand aggressive chemicals as well as elevated temperature conditions. Additionally, the EPDM (Ethylene Propylene) type is ideal for use with water, steam, and polar solvents.

Each elastomer compound ensures dependable resistance against compression set and maintains sealing integrity in a variety of gland designs, whether static or dynamic. This makes the Parker 2-series O-rings a reliable choice for numerous industrial sealing applications.

Features:

The AS568A series complies fully with dimensional standards, being molded to precise dash-number tolerances. This ensures seamless drop-in interchangeability, making it highly reliable for various applications.

One notable feature of the 2-201 to 2-284 series is its uniform cross-section diameter of 3.53 mm, with a tolerance of ±0.10 mm. This consistency across the entire series simplifies the design of glands and facilitates easier spare-parts management.

When it comes to material options, the series includes NBR (Nitrile), which is known for its excellent resistance to petroleum oils, fuels, and hydraulic fluids. NBR seals typically operate effectively within a temperature range of approximately -34°C to +100°C (-30°F to +212°F).

For applications requiring superior chemical resistance, the FKM (Fluoroelastomer) variant offers high durability against aggressive chemicals, acids, and fuels. Its standard operating temperature spans from about -25°C to +200°C (-13°F to +392°F).

The EPDM (Ethylene Propylene) material is ideally suited for water and steam services, particularly in environments involving hot water, steam, or polar solvents. This type is typically rated for temperatures ranging from roughly -50°C to +150°C (-58°F to +302°F).

Covering a broad size range, the series includes 84 dash numbers, from 2-201 up to 2-284. This range accommodates inner diameters approximately from 7.59 mm to as large as 456.06 mm, providing versatile options for diverse sealing needs.

Technical Parameters:

Applications:

In hydraulic and pneumatic systems, NBR O-rings are commonly utilized. These seals are essential for cylinder seals, valve bodies, and fluid line connections, providing reliable performance under various pressures.

For chemical processing applications, FKM O-rings are preferred. They are designed to withstand harsh environments and are used in pump housings, reactor seals, and transfer lines that handle aggressive media.

When it comes to water and steam systems, EPDM O-rings offer excellent resistance. These seals are ideal for boiler fittings, hot water valves, and sanitary process lines, ensuring durability in high-temperature and moisture-rich conditions.

In general industrial assembly, AS568 2-series O-rings are widely applied. These versatile seals are used in gearboxes, actuators, flanges, and standard gland sealing, providing dependable sealing solutions across various machinery and components.
