FPM O-Ring 34.5x2.65 FKM Viton®

Technical sealing for industrial and automotive applications

High durability and chemical resistance

Main description

The FPM O-Ring 34.5x2.65 made from FKM (Viton®) is a high-performance technical sealing component designed for demanding industrial and automotive environments. With an inner diameter of 34.5 mm and a cross-section of 2.65 mm, it ensures precise fit and reliable sealing in both static and dynamic applications exposed to oils, greases and fuels.

FPM / FKM material is known for its excellent resistance to oils and lubricants, high thermal stability and strong chemical resistance. These properties make this O-ring suitable for use alongside a shaft seal, oil seal or rotary sealing element in machines, engines and hydraulic or pneumatic systems. Compared to standard NBR O-rings, FPM offers significantly longer service life and improved resistance to ageing.

The FPM O-Ring 34.5x2.65 is widely used in industrial applications where sealing reliability, dimensional stability and long-term performance are essential. It can be installed in stationary connections as well as near rotating components such as engine oil seals, rotary shaft seals and precision mechanical assemblies. This makes it a preferred solution for B2B customers seeking durable and consistent sealing performance.

The FKM compound, also commonly known under the trade name Viton, is an industry standard in applications requiring resistance to high temperatures, aggressive media and continuous operation.
