RS PRO Fluorelastomer O-Ring, 70 mm Inside Diameter, 77 mm Outside Diameter, 3.5 mm Thickness, Shore A 79 Hardness 196-5894

RS PRO 196-5894 Fluorelastomer O-Ring is a precision-engineered sealing component manufactured from premium fluorelastomer (FKM) material, known for its high chemical resistance and mechanical durability. Featuring an inside diameter of 70 mm, outside diameter of 77 mm, and 3.5 mm thickness, this O-ring provides a reliable seal in industrial, hydraulic, pneumatic, automotive, and chemical applications.

The black O-ring exhibits Shore A 79 hardness, balancing flexibility and resilience, suitable for a wide operating temperature range from -15°C to 200°C. Its robust construction makes it ideal for use as shaft seals, face-to-face seals, or in applications requiring rotary and linear motion sealing.

This O-ring is resistant to various hydrocarbons, oils, and fuels, ensuring long-lasting performance and reducing maintenance needs. However, it is not compatible with glycol-based brake fluids, ammonia gas, amines, alkalis, or superheated steam, which must be considered when selecting for specific environments.

Applications include sealing pumps, drive belts, hydraulic equipment, power transmission systems, automotive manufacturing, and industrial machinery where preventing fluid or air leakage is critical. The O-Ring helps maintain system pressure and prevents contamination by particles, vapors, or debris.

Constructed from chemically resistant fluorelastomer (FKM) material. Designed for operating temperatures between -15°C and 200°C. Precision sizing with 70 mm ID, 77 mm OD, and 3.5 mm thickness. Black color and Shore A 79 hardness provide durability and flexibility.

Suitable for hydraulic, pneumatic, automotive, and general engineering uses. Ensures effective sealing to prevent leakage and contaminant ingress. Offers excellent life span under recommended operating conditions. Excludes use with glycol brake fluids, ammonia, amines, alkalis, and superheated steam.
