Product Description:

Parker AS568 2-Series O-Rings, covering sizes from 2-001 to 2-050, are miniature sealing rings precisely molded from elastomeric materials. These O-rings feature a consistent cross-sectional diameter of 0.070 inches (1.78 mm). Designed in accordance with AS568A dimensional standards, they come in four distinct high-performance polymer types: NBR (nitrile), FKM (fluorocarbon), EPDM (ethylene propylene), and VMQ (silicone). Each polymer is specifically engineered to meet different requirements related to fluids, temperature ranges, and environmental conditions.

The 2-Series is specifically engineered to provide reliable sealing in applications where space is limited and pressures are low to medium, suitable for both static and lightly dynamic environments. The inside diameter of these O-rings varies from as small as 0.029 inches (0.74 mm) for the 2-001 size, up to 2.989 inches (75.92 mm) for the 2-050 size. This range includes the smallest standardized AS568 sizes, making these O-rings ideal for use in sensors, compact fittings, miniature valves, analytical instruments, and small pneumatic or hydraulic components.

Depending on the specific application needs, Parker’s 2-Series O-Rings offer options such as NBR for superior oil resistance, FKM for outstanding chemical and temperature stability, EPDM for excellent resistance to hot water, steam, and weather conditions, and VMQ for broad temperature flexibility combined with physiological inertness. This product line provides a standardized, ready-to-use sealing solution characterized by consistent material quality and widespread availability worldwide.

Applications:

Precision instruments and sensors benefit from specialized small ports, transducer housings, and enclosures designed specifically for analytical devices. These components ensure reliable performance in sensitive measurement environments.

In the realm of miniature pneumatic and hydraulic systems, compact cylinders, small-bore actuators, valve bodies, and fitting seals play a critical role. Their design focuses on efficiency and space-saving without compromising functionality.

The automotive and transportation sectors utilize various components such as fuel system parts, small fluid connectors, sensor seals, and brake system sub-assemblies. Notably, EPDM materials are employed for applications involving glycol-based fluids to ensure durability and compatibility.

For medical and life-science equipment, VMQ grades that comply with FDA and USP Class VI standards are ideal for fluid-path seals. These materials are commonly used in diagnostic and laboratory devices, guaranteeing safety and reliability.

Food and beverage processing industries require EPDM and VMQ compounds that meet specific compliance standards suitable for potable water and food-contact areas, thus maintaining hygiene and safety throughout processing.

Semiconductor and high-purity systems demand materials like FKM and specially cleaned VMQ options. These are tailored for chemically aggressive environments or high-temperature conditions commonly found in miniature applications.

General industrial sealing solutions include components such as gearboxes, pumps, small flanges, and end-caps. These parts are designed for tight spaces and adhere to AS568 standardization to ensure interchangeability and effectiveness.

Finally, rotary seal auxiliary elements often incorporate small 2-series O-rings functioning as energizers or auxiliary seals within certain PTFE rotary seal assemblies, enhancing overall sealing performance.
