177.19x6.99 X-ring NBR75

X-ring is a seal for hydraulic oils and lubricating oils in linear or rotational systems. The characteristics of this X-ring make it the ideal replacement for an O-ring seal in slow, dynamic applications. This product offers standardised quality and is widely used in the hydraulics sector and general industry. This X-ring has an operating temperature range of -30°C to +120°C. X-ring has a Shore A hardness of 75. As a result, this O-ring is suitable for applications with a pressure of up to 80 bars. At higher pressures (above 50 bars), we recommend using back-up rings in addition to an X-ring. Nitrile rubber is suitable for most applications that involve oils and greases. It is not resistant to ozone or UV radiation. Furthermore, it does not tolerate some organic oils or greases well, and should not be used for high-temperature applications. In such cases, an FKM or X-ring is a better choice (depending on the application). Recommended in: Chemical
