Product Description:
Parker 3-series O-rings are expertly crafted elastomeric seals that adhere to the AS568A dimensional standards. These precision-molded components are specifically designed for use in internal straight thread fluid connection bosses and tube fittings, referencing industry specifications such as MS33656, MS357, and SAE straight thread O-ring boss standards.
This series includes a wide range of sizes, covering dash numbers 3-901 through 3-932. The inside diameters of these O-rings range from 4.70 mm (0.185 inches) to 59.36 mm (2.337 inches). Their cross-sectional thickness, also known as the cord width, varies between 1.42 mm (0.056 inches) and 3.00 mm (0.118 inches), accommodating various sealing requirements.
To suit different fluid compatibility and temperature demands, Parker offers these O-rings in four main elastomer families. NBR (Nitrile) is ideal for general-purpose petroleum products and hydraulic systems. FKM (Fluoroelastomer) is suitable for aggressive chemical environments and high-temperature applications. EPDM (Ethylene Propylene) is recommended for water, steam, and polar solvents. Lastly, VMQ (Silicone) serves applications requiring extreme temperature resistance and high purity standards.
Features:
The straight thread boss is precisely sized to match SAE straight thread O-ring ports. This ensures a secure and leak-tight seal against the chamfered face of the port, enhancing reliability in hydraulic systems.
Our products comply with the AS568A dimensional standards, molded exactly to dash-number tolerances. This allows for easy drop-in interchangeability without the need for custom fitting.
The NBR (Nitrile) material is designed for general purpose use, offering excellent resistance to petroleum-based hydraulic fluids, oils, and fuels. It performs well within a typical temperature range from approximately -34°C to +100°C (-30°F to +212°F).
FKM (Fluoroelastomer) seals provide exceptional chemical resistance. They withstand aggressive chemicals, acids, and high-temperature fluids, operating effectively between -25°C and +200°C (-13°F to +392°F).
EPDM (Ethylene Propylene) is particularly suitable for applications involving hot water, steam, and polar solvents such as ketones and alcohols. Its operating temperature range spans roughly -50°C to +150°C (-58°F to +302°F).
VMQ (Silicone) offers extreme temperature flexibility with a wide service window from about -55°C to +200°C (-67°F to +392°F). This makes it ideal for high-purity environments and applications requiring performance across varied temperatures.
All seals feature precision-molded geometry to ensure consistent compression set resistance. This design provides dependable sealing performance and maintains integrity under high-pressure hydraulic conditions.
