Parker AS568 O-Ring 2-102 2-103 2-104 2-105 2-106 2-107 2-108 2-109 ID 1.24mm-7.59mm CS 2.62mm NBR FKM VMQ Low Compression Set Seal For Precision Instrument Fitting

Product Description:

Parker 2-series O-rings are meticulously crafted elastomeric seals that conform to the AS568A dimensional standards. This specific range includes dash numbers from 2-102 up to 2-178, all sharing a consistent cross-sectional thickness of 2.62 mm (0.103 inches). The internal diameters vary significantly, starting from as small as 1.24 mm for the 2-102 size to as large as 247.32 mm for the 2-178 size. This wide variety allows these O-rings to accommodate an extensive array of gland sizes, from tiny precision instruments to large-scale industrial housings.

The Parker 2-series O-rings come in three main elastomer categories, each designed to satisfy specific fluid compatibility and temperature criteria. The NBR (Nitrile) option is ideal for general-purpose applications involving petroleum-based fluids and hydraulic systems. For environments involving harsh chemicals and elevated temperatures, the FKM (Fluoroelastomer) compound offers superior resistance. Finally, the VMQ (Silicone) variant is engineered for extreme temperature conditions and applications requiring high purity standards.

Every compound within this series ensures dependable resistance to compression set and maintains excellent sealing performance. These O-rings are effective in both static seals and dynamic gland environments, making them versatile components in a wide range of sealing applications.

Features:

The AS568A series is molded to meet the standard dash-number tolerances, ensuring seamless drop-in interchangeability. This precise dimensional compliance guarantees compatibility across various applications without requiring modifications.

All sizes within the 2-102 to 2-178 series maintain a uniform cross-sectional diameter of 2.62 ± 0.08 mm. This uniformity simplifies both gland design and the planning of spare parts inventories, enhancing efficiency in maintenance and assembly processes.

NBR, or Nitrile, offers excellent resistance against petroleum oils, fuels, and hydraulic fluids. It typically operates effectively within a temperature range of approximately -34°C to +121°C (-30°F to +250°F), making it suitable for a wide range of general-purpose sealing applications.

FKM provides high resistance to aggressive chemicals, acids, and fuels. Its standard service temperature range extends from about -26°C to +204°C (-15°F to +400°F). Additionally, specialized low-temperature compounds are available, enabling use down to -46°C, broadening its application potential in harsh environments.

VMQ, or Silicone, is designed for applications requiring extreme temperature adaptability. It performs reliably within a broad range from approximately -54°C to +232°C (-65°F to +450°F). This makes it ideal for high-purity and medical applications where temperature stability and material purity are critical.

The O-rings are available in standard Parker compounds such as N0674-70, V0747-75, and S0604-70. These formulations ensure consistent hardness and compression set properties, guaranteeing reliable performance across various operating conditions.

The series covers a broad range of sizes, with 77 dash numbers spanning from 2-102 to 2-178. This encompasses inner diameters ranging from 1.24 mm up to 247.32 mm, providing ample options to meet diverse sealing requirements.

Technical Parameters:

Applications:

In the realm of hydraulic and pneumatic systems, NBR O-rings are commonly utilized. These seals play a critical role in cylinder seals, valve bodies, and fluid line connections, ensuring reliable performance under various operating conditions.

For chemical processing applications, FKM O-rings are preferred due to their excellent resistance to aggressive media. They are typically used in pump housings, reactor seals, and transfer lines that handle harsh chemicals.

When dealing with high-temperature and high-purity environments, VMQ O-rings are the ideal choice. These seals are widely applied in analytical instruments, cleanroom equipment, and thermal processing systems, where maintaining purity and withstanding elevated temperatures is essential.

In general industrial assembly, the AS568 2-series O-rings are standard components. They are frequently employed in gearboxes, actuators, flanges, and provide effective sealing in standard gland applications.
