You use this black FFKM O-ring as a seal for steam, oils, acids, bases and solvents in static and slow dynamic applications. This product is the best-sold Kalrez® O-ring because of its extensive applicability. You mainly find these seals in the petrochemical and chemical industries.

Application

Temperature resistance
The Kalrez® 6375 O-ring has an operating temperature range from -20°C to +275°C.

Maximum pressure
Compound 6375 has a Shore A hardness of 75. This makes it suitable for applications with a pressure of up to 80 bars. Note that you must also strictly adhere to the guidelines in the chart below. This chart shows the relationship between the hardness of your O-ring, the pressure in your application, the groove size and the seal clearance gap.

Are you going to use this seal in a slow, dynamic application with a pressure of 50 bars or higher? If so, we advise you to use back-up rings.

Chemical resistance
This rubber material offers good chemical resistance across a very broad spectrum. So it is ideal for applications involving high temperatures (e.g. steam) and strong chemicals, such as amines and solvents.
