202.57x6.99 X-ring FKM75

FKM X-ring a seal for lubricating and hydraulic oils at high temperatures in linear or rotational applications. The characteristics of this X-ring make it the ideal replacement for an O-ring seal in slow, dynamic applications. This seal is widely applicable and often found in the chemicals and hydraulics sectors, and in general industry. Viton, the brand name for FKM, may be more familiar to you. This FKM 75 X-ring has an operating temperature range of -20°C to +200°C. X-ring has a Shore A hardness of 75. As a result, this X-ring is suitable for applications with a pressure of up to 80 bars. At higher pressures, we recommend using back-up rings in addition to an X-ring. This material is an excellent solution for applications that involve lubricating and hydraulic oils. It also offers a good resistance to acids, bases, greases, ageing and UV radiation. Furthermore, FKM is often used in combination with a vacuum.
