RS PRO Fluorelastomer O-Ring, 38 mm ID, 42 mm OD, Shore A 79, 196-5735

The RS PRO 196-5735 Fluorelastomer O-Ring is a precision-engineered sealing solution designed for fluid power, mechanical, and general engineering systems. Made from high-quality fluorelastomer (FKM), this O-ring offers exceptional resistance to chemicals, oils, and most hydrocarbons, making it ideal for demanding industrial environments. Its metric size provides a 38 mm inside diameter and a 42 mm outside diameter with a 2 mm thickness, ensuring compatibility across pump, drive belt, and power transmission assemblies.

With Shore A 79 hardness and an operating temperature range from -15°C to 200°C, this component is built to deliver consistent sealing performance over a wide variety of conditions - from laboratory to automotive, hydraulic, and pneumatic applications. The black fluorelastomer construction provides resilient sealing under dynamic movement, supporting both rotary and linear motion in shafts and flanges, while holding up against wear and degradation.

RS PRO O-rings are commonly seated between two mating surfaces, forming an airtight seal when compressed. They prevent leaks by blocking fluid, air, vapor, and particulate ingress, thereby maintaining system pressure and operational safety. This makes the 196-5735 O-ring well-suited for industrial manufacturing, plumbing, hydraulics, automotive maintenance, repair, and power transmission equipment.

Given its compatibility with most hydrocarbons, oils, and fuels, the O-ring is used in aircraft, automotive, and chemical industries, providing maintenance-free performance where chemical exposure and temperature fluctuations are routine. However, it should not be used with glycol-based brake fluids, ammonia, alkalis, superheated steam, or low molecular weight organic acids.

Users benefit from the long life of RS PRO fluorelastomer O-rings, which deliver stable performance and efficient sealing for pumps, drive assemblies, pressure containers, and hydraulic circuits. These O-rings assure reliability for both new installations and as replacement parts in demanding environments.

Typical applications for this O-ring include industrial manufacturing, power transmission systems, automotive repair, hydraulics, pneumatics, and plumbing installations where robust sealing and chemical resistance are essential.
