FAQ

What is the main advantage of FKM material for this oil seal?

The primary advantage of FKM (Fluoroelastomer) is its excellent thermal and chemical resistance. It can operate at much higher temperatures (up to 200 deg C) and withstand aggressive fluids, oils, and chemicals that would degrade standard materials like NBR.

What does the ‘B’ in DIN 3760-B signify in the design of this seal?

The ‘B’ form in the DIN 3760 standard specifies a design with a metal outer casing that is covered with rubber on its outside diameter. It also features a spring-loaded sealing lip for effective sealing pressure on the shaft.

What are the typical operating temperature limits for an FKM oil seal like this?

Generally, FKM seals can operate continuously in a temperature range from -20 deg C to +200 deg C (-4 deg F to +392 deg F), with short-term capabilities to handle even higher temperatures, depending on the specific media.
