Product Description:
Parker 3-series O-rings are precision-molded elastomeric seals crafted according to AS568A dimensional standards. They are specifically designed to be used with internal straight thread fluid connection bosses and tube fittings, referencing standards such as MS33656, MS357, and SAE straight thread O-ring boss specifications.
This product line includes dash numbers ranging from 3-901 to 3-932. The O-rings feature inside diameters that vary from 4.70 mm (0.185 inches) up to 59.36 mm (2.337 inches). Their cross-sections, or cord widths, range between 1.42 mm (0.056 inches) and 3.00 mm (0.118 inches).
To accommodate a wide variety of fluid and temperature demands, these O-rings are offered in four main elastomer families. The NBR (Nitrile) compound is suited for general-purpose petroleum and hydraulic applications. FKM (Fluoroelastomer) is ideal for handling aggressive chemicals and elevated temperatures. EPDM (Ethylene Propylene) is used in environments involving water, steam, and polar solvents. Lastly, VMQ (Silicone) elastomers perform well in extreme temperature conditions and are suitable for high-purity applications.
Features:
The Straight Thread Boss Compatibility is designed specifically for SAE straight thread O-ring ports. This precise sizing ensures a leak-tight seal against the chamfered port face, enhancing system reliability.
Compliance with AS568A dimensional standards is maintained by molding these seals to standard dash-number tolerances. This allows for seamless drop-in interchangeability within existing systems.
The NBR (Nitrile) material is a general-purpose option, offering excellent resistance to petroleum-based hydraulic fluids, oils, and fuels. It typically operates within a temperature range of approximately -34°C to +100°C (-30°F to +212°F).
FKM (Fluoroelastomer) seals provide superior chemical resistance, particularly against aggressive chemicals, acids, and high-temperature fluids. Their standard service range spans roughly -25°C to +200°C (-13°F to +392°F).
EPDM (Ethylene Propylene) is ideally suited for applications involving hot water, steam, and polar solvents such as ketones and alcohols. Its typical temperature rating ranges from -50°C to +150°C (-58°F to +302°F).
VMQ (Silicone) delivers exceptional temperature flexibility, functioning effectively across a wide service window of approximately -55°C to +200°C (-67°F to +392°F). This makes it ideal for high-purity and extreme temperature environments.
In addition, the precision-molded geometry of these seals ensures consistent compression set resistance. This feature is critical for maintaining reliable sealing integrity, especially in high-pressure hydraulic systems.
