Parker AS568 Elastomer O‑Ring 3‑928 3‑932, ID 53.09MM 59.36MM CS 3MM NBR/FKM/EPDM/VMQ Steam Resistant For Food‑Grade Processing Vessel Port Repair Spare Parts

Product Description:

The Parker 3-series O-rings are precision-engineered elastomeric seals that conform to the AS568A dimensional standards. They are specifically designed for use with internal straight thread fluid connection bosses and tube fittings, adhering to specifications such as MS33656, MS357, and SAE straight thread O-ring boss standards.

This product line includes dash numbers ranging from 3-901 to 3-932. The O-rings feature inside diameters that vary between 4.70 mm (0.185 inches) and 59.36 mm (2.337 inches). Their cross-sectional sizes, or cord widths, span from 1.42 mm (0.056 inches) up to 3.00 mm (0.118 inches).

To accommodate a wide range of fluid and temperature conditions, these O-rings are offered in four main elastomer types. NBR (Nitrile) is suited for general-purpose petroleum and hydraulic applications; FKM (Fluoroelastomer) is ideal for aggressive chemicals and high temperatures; EPDM (Ethylene Propylene) is designed for use with water, steam, and polar solvents; and VMQ (Silicone) is perfect for extreme temperature environments and high-purity requirements.

Features:

The straight thread boss is specifically designed to fit SAE straight thread O-ring ports, guaranteeing a leak-tight seal by matching the chamfered face of the port. This precise sizing ensures dependable performance in hydraulic systems.

Our seals comply with AS568A dimensional standards, molded according to standard dash-number tolerances. This allows for easy drop-in interchangeability without the need for modifications.

NBR, or nitrile rubber, serves as a general-purpose material offering excellent resistance to petroleum-based hydraulic fluids, oils, and fuels. It typically operates effectively within a temperature range of approximately -34°C to +100°C (-30°F to +212°F).

FKM, also known as fluoroelastomer, provides superior chemical resistance. It is highly resistant to aggressive chemicals, acids, and high-temperature fluids, functioning well between roughly -25°C and +200°C (-13°F to +392°F).

EPDM, or ethylene propylene diene monomer, is particularly suitable for applications involving hot water, steam, and polar solvents such as ketones and alcohols. It typically operates in a temperature range of about -50°C to +150°C (-58°F to +302°F).

VMQ, or silicone rubber, offers exceptional flexibility across an extreme temperature range from approximately -55°C to +200°C (-67°F to +392°F). It is especially ideal for high-purity requirements and environments with wide-ranging temperatures.

All seals feature precision-molded geometry, which provides consistent compression set resistance and ensures reliable sealing integrity, particularly in demanding high-pressure hydraulic systems.

Technical Parameters:

Applications:

Hydraulic systems and manifolds commonly utilize sealing solutions for SAE straight thread ports found on hydraulic pumps, motors, and valve bodies. These seals play a crucial role in maintaining system integrity and preventing fluid leaks.

Tube fittings and connectors are essential components used in both adjustable and non-adjustable fluid line fittings. They ensure secure and reliable connections throughout various hydraulic and fluid systems.

In the automotive and mobile hydraulics sector, sealing and connection technologies are applied to transmission lines, power steering assemblies, and braking system ports. These applications demand high performance to withstand varying pressures and operating conditions.

Industrial fluid power equipment, including cylinder ports, gearboxes, and hydraulic power units, relies on specialized sealing techniques to ensure efficient and leak-free operation under heavy-duty conditions.

The aerospace and marine industries require fluid connection bosses that conform to rigorous MS and SAE standards. Compliance with these standards is vital to guarantee safety and functionality in demanding environments.
