Parker AS568 O-Ring 2-260 2-261 2-262 2-263 2-264 2-265 2-266 2-267 2-268 ID 164.70mm-215.50mm CS 3.53mm NBR FKM EPDM Heavy Dust Proof Gasket For Mining Rotary Feeder And Dust Collector Housing

Product Description:

The Parker 2-series O-rings are precision-manufactured elastomeric seals that conform to the AS568A dimensional standards. This product line spans dash numbers 2-201 through 2-284, each with a consistent cross-sectional thickness of 3.53 mm (0.139"). The inside diameters vary widely, starting from approximately 7.59 mm in the 2-201 size and reaching up to 456.06 mm in the 2-284 size, accommodating a diverse range of gland dimensions from small hydraulic fittings to large-scale industrial housings.

These O-rings come in three different elastomer types tailored to meet various fluid compatibility and temperature resistance needs. The NBR (Nitrile) variant is suitable for general-purpose applications involving petroleum products and hydraulic fluids. FKM (Fluoroelastomer) O-rings are designed to withstand aggressive chemical exposure and higher temperature conditions. Meanwhile, EPDM (Ethylene Propylene) options are ideal for use with water, steam, and polar solvents.

Each material formulation delivers reliable performance by resisting compression set and maintaining sealing effectiveness in both static and dynamic gland environments. This ensures dependable sealing solutions across a broad spectrum of industrial applications.

Features:

The AS568A dimensional compliance ensures that the seals are molded according to the standard dash-number tolerances. This guarantees drop-in interchangeability, making it easy to replace or fit seals without compatibility issues.

The entire 2-201 to 2-284 series features a uniform cross-section of 3.53 mm, with a tolerance of ± 0.10 mm. This consistency in the seal profile helps to simplify gland design and assists in efficient spare-parts management.

NBR, also known as Nitrile, serves as a general-purpose material with excellent resistance to petroleum oils, fuels, and hydraulic fluids. Its typical operating temperature range spans from approximately -34°C to +100°C (-30°F to +212°F), making it suitable for many common applications.

For more aggressive environments, FKM (Fluoroelastomer) offers superior chemical resistance. It resists harmful chemicals, acids, and fuels effectively and operates within a temperature range of about -25°C to +200°C (-13°F to +392°F), providing durability in demanding conditions.

EPDM (Ethylene Propylene) is the preferred choice for water and steam service. It performs well with hot water, steam, and polar solvents, with an operating range roughly from -50°C to +150°C (-58°F to +302°F), making it ideal for such applications.

This range covers a broad size selection across 84 dash numbers, from 2-201 to 2-284. The internal diameters covered extend from approximately 7.59 mm up to 456.06 mm, offering comprehensive size options to meet diverse sealing requirements.

Applications:

In hydraulic and pneumatic systems, NBR O-rings are commonly utilized for sealing cylinder components, valve bodies, and connections within fluid lines. Their durability and resistance make them ideal for maintaining system integrity under varying pressures.

When it comes to chemical processing, FKM O-rings are preferred due to their excellent chemical resistance. These O-rings are typically employed in pump housings, reactor seals, and pipelines designed for the transfer of aggressive media, ensuring reliable containment of harsh substances.

For water and steam applications, EPDM O-rings provide effective sealing solutions. They are often used in boiler fittings, hot water valves, and sanitary process lines, where their resistance to heat and water makes them highly suitable.

In general industrial assembly, the AS568 2-series O-rings are widely applied. These O-rings serve important sealing functions in gearboxes, actuators, flanges, as well as standard gland applications, offering reliable performance across various mechanical assemblies.
