RS PRO Fluorelastomer O-Ring, 44.17 mm ID, 47.73 mm OD, AS568-31, Black, Shore A 79 Hardness 196-5935

RS PRO 196-5935 Fluorelastomer O-Ring is a high-performance sealing solution for pumps, drive belts, and general engineering needs across hydraulic, pneumatic, and automotive systems. Its robust fluorelastomer construction delivers exceptional durability and resistance to aggressive chemicals, oils, and fuels. The o-ring design with a 44.17 mm inside diameter and 47.73 mm outside diameter makes it compatible with various shaft and face configurations, providing secure seals against particle, vapor, and fluid leakage for maintaining system pressure and cleanliness.

Engineered to meet AS568-31 standards, this O-ring ensures quality assurance and precise fit. Its Shore A 79 hardness is optimized for a wide range of demanding applications, accommodating rotary and linear movement without compromising seal integrity. The black fluorelastomer material remains resilient within an operating temperature span of -15°C to 200°C, supporting installation in both low- and high-temperature environments commonly found in industrial and laboratory facilities.

Applications extend to plumbing, hydraulic systems, pneumatic assemblies, power transmission units, and automotive repairs, where prevention of leaks and contamination is critical for consistent performance and safety. The O-ring design allows for straightforward compression between components, forming an effective barrier against unwanted ingress or egress of fluids, gases, and particulates.

Compatible with a broad spectrum of hydrocarbons, oils, and fuels, the RS PRO Fluorelastomer O-Ring is particularly favored in the aircraft, chemical, and automotive industries, where longevity and chemical resilience are priorities. Users should note the exclusion for glycol-based brake fluids, ammonia gas, amines, alkalis, superheated steam, and low molecular weight organic acids to prevent material degradation.

Premium fluorelastomer material offers prolonged chemical resistance and reliability. Configured for shaft and face-to-face sealing; supports rotary and linear motion. Engineered for hydraulic, pneumatic, manufacturing, and automotive applications.

Wide operating temperature range delivers versatility for harsh environments. Complies with international AS568-31 standards for safety and fit. Long-life seal solution designed to safeguard equipment and processes. Excellent resistance to most hydrocarbons, oils, and fuels ensures minimal maintenance.

Ideal for industrial, laboratory, and commercial settings.
