Parker AS568 O-Ring 2-163 2-164 2-165 2-166 2-167 2-168 2-169 2-170 ID 152.07mm-196.52mm CS 2.62mm NBR FKM VMQ Anti Media Swell Gasket For Chemical Reactor Lid And Batch Mixing Tank Seal

Product Description:

Parker 2-series O-rings are precision-engineered elastomeric seals that conform to the AS568A dimensional standards. This series encompasses dash numbers ranging from 2-102 to 2-178, all sharing a consistent cross-section thickness of 2.62 mm (0.103"). The inside diameters vary widely, starting from 1.24 mm (2-102) and extending up to 247.32 mm (2-178), thus accommodating a vast array of gland sizes, from small-scale instrumentation to large industrial enclosures.

These O-rings are offered in three main types of elastomer materials, each tailored to suit specific fluid and temperature conditions. The first is NBR (Nitrile), ideal for general-purpose applications involving petroleum and hydraulic fluids. Secondly, FKM (Fluoroelastomer) is designed to withstand harsh chemicals and high-temperature environments. Lastly, VMQ (Silicone) is suitable for extreme temperature variations and applications requiring high purity.

Each elastomer compound is engineered to deliver dependable compression set resistance and maintain sealing performance in both static and dynamic gland configurations. This ensures optimal reliability and durability across a wide range of sealing applications.

Features:

The AS568A dimensional compliance ensures that the seals are molded to adhere strictly to standard dash-number tolerances. This precision allows for easy drop-in interchangeability, making replacements and maintenance straightforward.

All models within the 2-102 to 2-178 series feature a uniform cross-section measuring 2.62 mm with a tolerance of ±0.08 mm. This consistent cord diameter facilitates simplified gland design and streamlines the planning process for spare parts inventory.

The NBR (Nitrile) compound is tailored for general-purpose applications, offering excellent resistance to petroleum oils, fuels, and hydraulic fluids. Its typical operating temperature ranges from approximately -34°C to +121°C (-30°F to +250°F), making it versatile for various industrial uses.

For environments requiring high chemical resistance, the FKM (Fluoroelastomer) material delivers superior protection against aggressive chemicals, acids, and fuels. It generally operates within a temperature span of -26°C to +204°C (-15°F to +400°F), and specialized low-temperature formulations can extend performance down to -46°C.

The VMQ (Silicone) compound is designed for extreme temperature flexibility. It supports a broad service range from around -54°C up to +232°C (-65°F to +450°F), making it particularly suitable for high-purity and medical applications where both cleanliness and temperature resilience are critical.

Precision molded compounds are available, including standard Parker formulations such as N0674-70, V0747-75, and S0604-70. These ensure consistent hardness levels and reliable compression set characteristics, supporting long-lasting seal performance.

The product line covers a broad spectrum of sizes, encompassing 77 dash numbers between 2-102 and 2-178. The inside diameters range from as small as 1.24 mm up to 247.32 mm, providing extensive options to suit various sealing requirements.

Technical Parameters:

This Pulse Valve Diaphragm is an ideal component for QBY diaphragm pump and QBY air diaphragm pump spare parts, ensuring reliable performance and compatibility with various media.

Applications:

Hydraulic and pneumatic systems commonly utilize NBR O-rings to ensure reliable sealing in cylinder seals, valve bodies, and fluid line connections. These O-rings provide excellent resistance to oils and hydraulic fluids, making them ideal for such demanding applications.

In the field of chemical processing, FKM O-rings are preferred for their ability to withstand harsh chemicals. They are widely used in pump housings, reactor seals, and transfer lines that handle aggressive media, offering durability and chemical resistance.

For applications requiring high temperature tolerance and high purity, VMQ O-rings are the go-to choice. These seals are employed in analytical instruments, cleanroom equipment, and thermal processing systems, where maintaining purity and withstanding elevated temperatures is critical.

General industrial assembly often relies on AS568 2-series O-rings. These standard-sized O-rings are suited for gearboxes, actuators, flanges, and standard gland sealing, providing a versatile and dependable sealing solution across various machinery and equipment.

Support and Services:

Our Pulse Valve Diaphragm is designed for optimal performance and durability in various industrial applications. To ensure the best results, it is important to follow proper installation and maintenance procedures.

Installation: Before installing the diaphragm, make sure the valve is clean and free of debris. Carefully align the diaphragm with the valve seat to prevent any damage or leaks. Avoid using excessive force during installation.

Maintenance: Regularly inspect the diaphragm for signs of wear, cracks, or deformation. Replace the diaphragm immediately if any damage is detected to maintain efficient valve operation. Clean the diaphragm using a soft cloth and mild detergent; avoid using harsh chemicals or abrasive materials.

Troubleshooting: If you experience issues such as air leakage, reduced valve performance, or unusual noises, check the diaphragm for proper seating and integrity. Ensure that all connections are secure and that the operating pressure is within the specified range.

Replacement Parts: Use only genuine replacement diaphragms recommended by the manufacturer to guarantee compatibility and performance. Installing non-standard parts may result in suboptimal operation or damage to the valve.

Technical Support: For detailed technical assistance, product specifications, or troubleshooting guidance, please refer to the product manual or visit our official website. Our support team is dedicated to helping you maximize the lifespan and efficiency of your pulse valve diaphragm.

Packing and Shipping:

Each Pulse Valve Diaphragm is carefully packaged to ensure maximum protection during transit. The diaphragm is first placed in a sealed plastic bag to prevent contamination from dust and moisture. It is then cushioned with foam inserts or bubble wrap to absorb any shocks or impacts.

The packaged diaphragm is placed inside a sturdy cardboard box, designed to withstand rough handling and stacking during shipping. Each box is clearly labeled with product details, handling instructions, and shipping information to ensure proper delivery.

For bulk orders, multiple units are securely packed in larger cartons with additional padding to prevent movement and damage. All packages are inspected thoroughly before dispatch to maintain the highest quality standards.

We use reliable shipping carriers to deliver the Pulse Valve Diaphragm products promptly and safely to our customers worldwide. Tracking information is provided so customers can monitor their shipment status at every stage.
